Polar Bears Unlikely to Thrive on Land-based Foods

USGS Newsroom - 9 hours 12 min ago
Summary: A team of scientists led by the U.S. Geological Survey found that polar bears, increasingly forced on shore due to sea ice loss, may be eating terrestrial foods including berries, birds and eggs, but any nutritional gains are limited to a few individuals and likely cannot compensate for lost opportunities to consume their traditional, lipid-rich prey—ice seals

ANCHORAGE, Alaska — A team of scientists led by the U.S. Geological Survey found that polar bears, increasingly forced on shore due to sea ice loss, may be eating terrestrial foods including berries, birds and eggs, but any nutritional gains are limited to a few individuals and likely cannot compensate for lost opportunities to consume their traditional, lipid-rich prey—ice seals.

“Although some polar bears may eat terrestrial foods, there is no evidence the behavior is widespread,” said Dr. Karyn Rode, lead author of the study and scientist with the USGS. “In the regions where terrestrial feeding by polar bears has been documented, polar bear body condition and survival rates have declined.”

The authors detail their findings in a review article in Frontiers in Ecology and the Environment. The scientists noted that over much of the polar bear’s range, terrestrial habitats are already occupied by grizzly bears. Those grizzly bears occur at low densities and are some of the smallest of their species due to low food quality and availability. Further, they are a potential competitor as polar bears displaced from their sea ice habitats increasingly use the same land habitats as grizzly bears. 

“The smaller size and low population density of grizzly bears in the Arctic provides a clear indication of the nutritional limitations of onshore habitats for supporting large bodied polar bears in meaningful numbers,” said Rode. “Grizzly bears and polar bears are likely to increasingly interact and potentially compete for terrestrial resources.”

The study found that fewer than 30 individual polar bears have been observed consuming bird eggs from any one population, which typically range from 900 to 2000 individuals. “There has been a fair bit of publicity about polar bears consuming bird eggs. However, this behavior is not yet common, and is unlikely to have population-level impacts on trends in body condition and survival,” said Rode.

Few foods are as energetically dense as marine prey. Studies suggest that polar bears consume the highest lipid diet of any species, which provides all essential nutrients and is ideal for maximizing fat deposition and minimizing energetic requirements. Potential foods found in the terrestrial environment are dominated by high-protein, low-fat animals and vegetation. Polar bears are not physiologically suited to digest plants, and it would be difficult for them to ingest the volumes that would be required to support their large body size.

“The reports of terrestrial feeding by polar bears provide important insights into the ecology of bears on land,” said Rode. “In this paper, we tried to put those observations into a broader context.  Focused research will help us determine whether terrestrial foods could contribute to polar bear nutrition despite the physiological and nutritional limitations and the low availability of most terrestrial food resources. However, the evidence thus far suggests that increased consumption of terrestrial foods by polar bears is unlikely to offset declines in body condition and survival resulting from sea ice loss.”

The review article was developed by researchers at the USGS, Washington State University, and Polar Bears International.

The USGS is leading studies of polar bear response to sea ice loss through its Changing Arctic Ecosystems Initiative. Current studies include examination of polar bear nutritional and behavioral ecology, linked to population-level consequences. For further information, visit the USGS Polar Bear Program.

USGS Releases Online Tool for Estimating Atrazine Levels in Streams and Rivers

USGS Newsroom Technical - 10 hours 59 min ago
Summary: A new online, interactive tool for estimating atrazine concentrations in streams and rivers is now available

A new online, interactive tool for estimating atrazine concentrations in streams and rivers is now available. 

The online mapping tool can assist water managers, policy makers, and scientists in several ways, including:

  • Understanding where and why pesticides occur in streams.
  • Assessing geographic patterns in pesticide stream concentrations at many scales, ranging from the watershed to regional and national;
  • Designing efficient and cost-effective monitoring programs and studies; and
  • Identifying streams with the greatest likelihood to have concentrations that exceed a water-quality benchmark of potential concern. 

“Assessment and management of pesticides require far more information on concentrations in streams and rivers than we can afford to directly measure for all the places and times of interest,” said Wes Stone, the USGS hydrologist who developed the model.  “For these situations, statistical models can be used to estimate water-quality conditions at unmonitored locations under a range of possible circumstances.” 

The estimates are based on a USGS statistical model — referred to as Watershed Regression for Pesticides (or “WARP”) — which also provides key statistics for each selected stream, including the probability that a pesticide may exceed a water-quality benchmark of potential concern, and a level of confidence and uncertainty associated with each estimate. 

The release for atrazine is the first in a series of statistical models for other pesticides, each of which is based on USGS National Water-Quality Assessment (NAWQA) monitoring in streams from 1992-2011, agricultural pesticide use, and environmental characteristics, such as soil characteristics, hydrology, and climate.  

Future updates will provide similar mapping and modeling for additional pesticides. Estimates and interactive mapping of pesticides for streams in the U.S. are available at this USGS website. The new website replaces an earlier version of the model for atrazine.  

Golden State Quads Add Trails

USGS Newsroom - 12 hours 42 min ago
Summary: Several of the 2,798 new US Topo quadrangles for California now display public trails along with segments of the Pacific Crest National Scenic Trail Newly released US Topo maps for California now feature selected trails and other substantial updates.

Mark Newell, APR ( Phone: 573-308-3850 ); Larry Moore ( Phone: 303-202-4019 );



Several of the 2,798 new US Topo quadrangles for California now display public trails along with segments of the Pacific Crest National Scenic Trail. Also the new maps now show improved data layers such as public land survey information, map symbol redesign, enhanced railroad information and new road source data. Some of the data for the trails is provided to the USGS through a nationwide “crowdsourcing” project managed by the International Mountain Biking Association (IMBA).

“The USGS 7.5-minute quads have been the long time gold standard for wall to wall mapping in the United States.” said Tom Lupo, Deputy Director, Data and Technology Division, California Department of Fish and Wildlife. “To me, they are the second best thing the Federal government has ever done!”

For California recreationalists and visitors who want to explore the diverse west coast landscape on a bicycle seat, hiking, horseback or other means, the new trail features on the US Topo maps will come in handy. During the past two years the IMBA, in a partnership with the MTB Project, has been building a detailed national database of trails. This activity allows local IMBA chapters, IMBA members, and the public to provide trail data and descriptions through their website.  MTB Project and IMBA then verify the quality of the trail data provided, ensure accuracy and confirm the trail is legal.  This unique crowdsourcing venture has increased the availability of trail data available through The National Map mobile and web apps, and the revised US Topo maps.

Another trail system, provided through a USGS partnership with the U.S. Forest Service, is the Pacific Crest National Scenic Trail. This west-coast long NST joins the Pacific Northwest National Scenic Trail, the Ice Age National Scenic Trail, the North Country National Scenic Trail, and the Appalachian National Scenic Trail as being featured on the new US Topo quads around the nation. The USGS hopes to eventually include all National Scenic Trails in The National Map products.

The Pacific Crest National Scenic Trail is a treasured pathway through some of the most scenic terrain in the nation. Beginning in southern California at the Mexican border, the PCT travels a total distance of 2,650 miles through California, Oregon, and Washington until reaching the Canadian border. The PCT is one of the original National Scenic Trails established by Congress in the 1968 National Trails System Act and fifty-four percent of the trail lies within designated wilderness

Another important addition to the new California US Topo maps is the inclusion of Public Land Survey System data. PLSS is a way of subdividing and describing land in the US. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior.

These new maps replace the first edition US Topo maps for the Golden State and are available for free download from The National Map, the USGS Map Locator & Downloader website , or several other USGS applications.

To compare change over time, scans of legacy USGS topo maps, some dating back to the late 1800s, can be downloaded from the USGS Historical Topographic Map Collection

The Act grants the Secretary of Interior and the Secretary of Agriculture authority over the National Trails System. The Act defines four types of trails. Two of these types, the National Historic Trails and National Scenic Trails, can only be designated by Act of Congress. National scenic trails are extended trails located as to provide for maximum outdoor recreation potential and for the conservation and enjoyment of nationally significant scenic, historic, natural, and cultural qualities of the area through which such trails may pass.

There are 11 National Scenic Trails:
  • Appalachian National Scenic Trail
  • Pacific Crest National Scenic Trail
  • Continental Divide National Scenic Trail
  • North Country National Scenic Trail
  • Ice Age National Scenic Trail
  • Potomac Heritage National Scenic Trail
  • Natchez Trace National Scenic Trail

New Technology Helps Identify Dispersal of Avian Flu Virus between Asia and Alaska

USGS Newsroom - Tue, 03/31/2015 - 13:00
Summary: In a new study published today, scientists from the U.S. Geological Survey and U.S. Fish and Wildlife Service harnessed a new type of DNA technology to investigate avian influenza viruses in Alaska

Contact Information:

Andy Ramey ( Phone: 907-786-7174 ); Paul Laustsen ( Phone: 650-329-4046 );



ANCHORAGE, Alaska — In a new study published today, scientists from the U.S. Geological Survey and U.S. Fish and Wildlife Service harnessed a new type of DNA technology to investigate avian influenza viruses in Alaska.  Using a “next generation” sequencing approach, which identifies gene sequences of interest more rapidly and more completely than by traditional techniques, scientists identified low pathogenic avian influenza viruses in Alaska that are nearly identical to viruses found in China and South Korea. 

The viruses were found in an area of western Alaska that is known to be a hot spot for both American and Eurasian forms of avian influenza.

“Our past research in western Alaska has shown that 70 percent of avian influenza viruses isolated in this area were found to contain genetic material from Eurasia, providing evidence for high levels of intercontinental viral exchange,” said Andy Ramey, a scientist with the USGS Alaska Science Center and lead author of the study.  “This is because Asian and North American migratory flyways overlap in western Alaska.”

The new study, led by the USGS, found low pathogenic H9N2 viruses in an Emperor Goose and a Northern Pintail.  Both of the H9N2 viruses were nearly identical genetically to viruses found in wild bird samples from Lake Dongting, China and Cheon-su Bay, South Korea.

“These H9N2 viruses are low pathogenic and not known to infect humans, but similar viruses have been implicated in disease outbreaks in domestic poultry in Asia,” said Ramey. 

There is no commercial poultry production in western Alaska and highly similar H9N2 virus strains have not been reported in poultry in East Asia or North America, so it is unlikely that agricultural imports influenced this result.

The finding provides evidence for intercontinental movement of intact avian influenza viruses by migratory birds. The USGS recently released a publication about the detection of a novel highly pathogenic H5N8 virus in the U.S. that is highly similar to the Eurasian H5N8 viruses. This suggests that the novel re-assortment may be adapted to certain waterfowl species, enabling it to survive long migrations. That virus, and associated strains, have now spread from early detections in wild and domestic birds in Pacific states to poultry outbreaks in Minnesota, Missouri and Arkansas.

“The frequency of inter-hemispheric dispersal events of avian influenza viruses by migratory birds may be higher than previously recognized,” said Ramey.

While some of the samples for the project came from bird fecal samples collected from beaches at Izembek National Wildlife Refuge, most of the samples came from sport hunters.

“For the past several years, we’ve worked closely with sport hunters in the fall to obtain swab samples from birds and that has really informed our understanding of wildlife disease in this area,” said Bruce Casler, formerly a biologist with the USFWS Izembek National Wildlife Refuge and a co-author of the study. None of the viruses found in harvested birds from Izembek Refuge are known to infect humans, but hunters should always follow safe meat handling and cooking guidelines when processing wild game.

The paper, “Dispersal of H9N2 influenza A viruses between East Asia and North America by wild birds” was published today in the journal Virology. A summary of all samples collected at the Izembek Refuge will be described in a subsequent publication.

Updated Information on Cuba Mineral and Petroleum Resources Released

USGS Newsroom - Tue, 03/31/2015 - 10:40
Summary: Cuba is among the top 10 producers of cobalt and nickel and has significant other mineral and petroleum resources, according to a new U.S. Geological Survey publication

Contact Information:

Steven Fortier ( Phone: 703-648-4920 ); Christian Quintero ( Phone: 813-352-3487 );



Cuba is among the top 10 producers of cobalt and nickel and has significant other mineral and petroleum resources, according to a new U.S. Geological Survey publication.

The report and accompanying map highlight the mineral resources available in Cuba, as well as detailing locations of petroleum exploration and development. The map also identifies mines, mineral processing facilities and petroleum facilities as well as information on location, operational status and ownership. It also addresses the current status of mineral industry projects, historical developments and trends of the Cuban economy with an emphasis on mineral industries and the supply of and demand for Cuba’s mineral resources.

“Cuba’s geology is complex, and the country has a variety of mineral commodity and energy resources,” said Steven Fortier, Director of the USGS National Minerals Information Center. “It is important that the public and industry have the latest information on the status of the mineral industry and the potential for natural resource development in Cuba.”

A few key points from the report are:

  • In 2013, Cuba was estimated to be among the world’s top ten producers of cobalt and nickel, which are the country’s leading exports
  • Cuba’s current crude oil and associated natural gas production from onshore and shallow water reservoirs is approximately 50,000 barrels per day of liquids and about 20,000 barrels per day oil equivalent of natural gas
  • In 2013, the value of mining and quarrying activities accounted for 0.6 percent of Cuba’s gross domestic product, compared with 1.4 percent in 2000
  • The value of production from Cuba’s industrial manufacturing sector increased by 88 percent between 1993 and 2013, whereas the sector’s share in the GDP decreased by 3 percent during the same period reflecting economic growth in other sectors of the economy

In 2004, the USGS released an assessment of the hydrocarbons of the North Cuba Basin and its three sub-basins. The total amount of undiscovered technically recoverable resources was estimated to be 9.8 trillion cubic feet of undiscovered natural gas, 4.6 billion barrels of crude oil, and 0.9 billion barrels of natural gas liquids. About 70 percent of this oil was estimated to be located no more than 50 to 80 kilometers (km) offshore along the length of the western and northern coasts of the island. To date, deepwater drilling has resulted in no commercially viable oil or gas discoveries. 

Industrial minerals and manufactured industrial mineral products produced in Cuba include ammonia and ammonia byproducts, bentonite, cement, feldspar, high-purity zeolite minerals, gypsum, kaolin (a type of clay), lime, high-grade limestone, marble, sand, sulfuric acid, steel and urea. In 2013, an estimated 4,500 metric tons of zeolites was exported to Europe and other Latin American countries and in 2014 the majority of the country’s ammonium nitrate was intended for export.

In 2014, Cuba’s Ministry of Foreign Trade and Investment announced 246 development projects for which it sought foreign investment. The petroleum sector offered the greatest number of prospective investment opportunities followed by the manufacturing and mining sectors. In the energy sector, the country is offering joint ventures in petroleum extraction from onshore and offshore blocks and foreign investment opportunities are being offered in biomass and solar energy production and hydroelectric power.

The report ‘Recent trends in Cuba’s mining and petroleum extraction industries’ FS 2015-3032 is available online.

New Report Indicates Potential for Five Times Known Copper Deposits Yet to Be Found in Central Asia

USGS Newsroom Technical - Mon, 03/30/2015 - 12:25
Summary: A new U.S. Geological Survey report covering major parts of the world’s largest mountain belt in central Asia estimates the existence of about five times as much copper in undiscovered deposits as has been identified to date

 );



SPOKANE, Wash. — A new U.S. Geological Survey report covering major parts of the world’s largest mountain belt in central Asia estimates the existence of about five times as much copper in undiscovered deposits as has been identified to date. These areas host 20 known porphyry copper deposits, including the world class Oyu Tolgoi deposit in Mongolia that was discovered in the late 1990s.

The results of this new assessment estimate the probability that there may be as many as 97 undiscovered porphyry copper deposits within the assessed permissive tracts, which would represent nearly five times the 20 known deposits. Grade and tonnage models predict estimated resources associated with undiscovered deposits as mean values of 370,000,000 metric tons of copper, 10,000 t of gold, 7,700,000 t of molybdenum, and 120,000 t of silver. These estimated mean tonnages are predictions based on comparisons to known deposits of similar type.

Copper was one of the first metals ever extracted and used by humans, and it has been one of the important materials in the development of civilization. Because of its properties, of high ductility, malleability, and thermal and electrical conductivity, and its resistance to corrosion, copper has become a major industrial metal, ranking third after iron and aluminum in terms of quantities consumed.

USGS scientists worked in collaboration with colleagues in the China Geological Survey, the Centre for Russian and Central Eurasian Mineral Studies, and the Russian Academy of Sciences to complete the assessment. Participants evaluated applicable grade and tonnage models and estimated numbers of undiscovered deposits at different confidence levels for each permissive tract. The estimates were then combined with the selected grade and tonnage models using Monte Carlo simulations to generate probabilistic estimates of undiscovered resources.  Additional resources in extensions of deposits with identified resources were not specifically evaluated.

The full report, USGS SIR 2010-5090-X, “Porphyry Copper Assessment of the Central Asian Orogenic Belt and eastern Tethysides— China, Mongolia, Russia, Pakistan, Kazakhstan, Tajikistan, and India,” is available online and includes a summary of the data used in the assessment, a brief overview of the geologic framework of the area, descriptions of permissive tracts and known deposits, maps, and tables. A geographic information system database that accompanies this report includes the tract boundaries and known porphyry copper deposits, significant prospects, and prospects. Assessments of overlapping younger rocks and adjacent areas are included in separate reports, which are also available online.

Appalachian Basin Energy Resources -- A New Look at an Old Basin

USGS Newsroom Technical - Wed, 03/25/2015 - 10:00
Summary: Appalachian coal and petroleum resources are still available in sufficient quantities to contribute significantly to fulfilling the nation’s energy needs, according to a recent study by the U.S. Geological Survey New Geological Compilation Available for Resource Studies and Land-Use Planning

Contact Information:

Leslie  Ruppert ( Phone: 703-648-6431 ); Alex Demas ( Phone: 703-648-4421 );



Appalachian coal and petroleum resources are still available in sufficient quantities to contribute significantly to fulfilling the nation’s energy needs, according to a recent study by the U.S. Geological Survey.

The Appalachian basin, which includes the Appalachian coalfields and the Marcellus Shale, covers parts of Alabama, Georgia, Kentucky, Maryland, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia and West Virginia.

“The study we conducted is a modern, in-depth collection of reports, cross sections and maps that describe the geology of the Appalachian basin and its fossil fuel resources,” said USGS scientist Leslie Ruppert, the study’s lead editor.

Petroleum resources, including oil and natural gas, remain significant in the Appalachian basin. Although both conventional oil and gas continue to be produced in the Appalachian basin, most new wells in the region are drilled in shale reservoirs, such as the famous Marcellus and Utica Shale, to produce natural gas.

The Appalachian basin contains significant coalbed methane and high-quality, thick, bituminous coal resources although the resource is deeper and thinner than the coal that has already been mined.

Although this volume is not a quantitative assessment of all notable geologic and fossil fuel localities in the Appalachian basin, the selected study areas and topics presented in the chapters pertain to large segments of the basin and a wide range of stratigraphic intervals. This updated geologic framework is especially important given the significance of shale gas in the basin.

This volume discusses the locations of coal and petroleum accumulations, the stratigraphic and structural framework, and the geochemical characteristics of the coal beds and petroleum in the basin, as well as the results of recent USGS assessments of coal, oil and gas resources in the basin. 

Many of the maps and accompanying data supporting the reports in this volume are available from chapter I.1 as downloadable geographic information system (GIS) data files about the characteristics of selected coal beds and oil and gas fields, locations of oil and gas wells, coal production, coal chemistry, total petroleum system (TPS) boundaries and bedrock geology. Log ASCII Standard (LAS) files for geophysical (gamma ray) wireline well logs are included in other chapters. 

USGS is the only provider of publicly available estimates of undiscovered technically recoverable oil and gas and coal resources of onshore lands and offshore state waters. This study of the Appalachian basin will underpin energy resource assessments and may be found online.

First Round of Lidar BAA Awards Released

USGS Newsroom Technical - Wed, 03/25/2015 - 09:30
Summary: The U.S. Geological Survey National Geospatial Program is pleased to announce the first round of awards resulting from the USGS Broad Agency Announcement (BAA) for the 3D Elevation Program (3DEP), initially issued on July 18, 2014. (Solicitation Number: G14PS00574)

Contact Information:

Diane Eldridge ( Phone: 703-648-4521 ); Mark Newell ( Phone: 573-308-3850 );



The U.S. Geological Survey National Geospatial Program is pleased to announce the first round of awards resulting from the USGS Broad Agency Announcement (BAA) for the 3D Elevation Program (3DEP), initially issued on July 18, 2014. (Solicitation Number: G14PS00574).

The BAA is a publicly accessible process to develop partnerships for the collection of lidar and derived elevation data for 3DEP.  The primary goal of 3DEP is to systematically collect nationwide lidar coverage (ifsar in Alaska) over an 8-year period to provide more than $690 million annually in new benefits to government entities, the private sector and citizens.

3DEP presents a unique opportunity for collaboration between all levels of government to leverage the services and expertise of private sector mapping firms that acquire the data, and to create jobs now and in the future. The USGS, along with other federal, state, local and private agencies, is establishing the collection program to respond to the growing needs for high-quality, three-dimensional mapping data of the United States.

 “We are very excited about the high level interest in the BAA as demonstrated by the number and dollar value of the proposals we received,” said Kevin Gallagher, USGS Associate Director for Core Science Systems.

Current and accurate 3D elevation data are essential to help communities cope with natural hazards and disasters such as floods and landslides, support infrastructure, ensure agricultural success, strengthen environmental decision-making and bolster national security. Lidar, short for light detection and ranging, is a remote sensing detection system that works on the principle of radar, but uses light from a laser. Similarly, interferometric synthetic aperture radar (ifsar) is used to collect data over Alaska.

Federal funds to support this opportunity were provided by the USGS, the Federal Emergency Management Agency and the Natural Resources Conservation Service. The USGS is acting in a management role to facilitate planning and acquisition for the broader community, through the use of government contracts and partnership agreements.

The Fiscal Year 2015 Awards offered partnership funding to 29 proposals in 25 States and Territories. The FY15 body of work is expected to result in the influx of more than 95,000 square miles of public domain lidar point cloud data and derived elevation products into the 3DEP program.

More information about 3DEP including updates on current and future 3DEP partnership opportunities is available online.

Laboratory Study Shows Future Generations of Fish Affected by Endocrine Disruptor Exposure

USGS Newsroom - Tue, 03/24/2015 - 11:00
Summary: Fish exposed to the endocrine-disrupting chemicals bisphenol A (BPA) or 17a-ethinylestradiol (EE2) in a laboratory have been found to pass adverse reproductive effects onto their offspring up to three generations later, according to a new study by the U.S. Geological Survey and the University of Missouri

Fish exposed to the endocrine-disrupting chemicals bisphenol A (BPA) or 17a-ethinylestradiol (EE2) in a laboratory have been found to pass adverse reproductive effects onto their offspring up to three generations later, according to a new study by the U.S. Geological Survey and the University of Missouri.

Aquatic environments are the ultimate reservoirs for many contaminants, including chemicals that mimic the functions of natural hormones. Fish and other aquatic organisms often have the greatest exposures to such chemicals during critical periods in development or even entire life cycles.

Scientists exposed fish to either BPA or EE2 for one week during embryonic development, while subsequent generations were never exposed. Future generations showed a reduced rate of fertilization and increased embryo mortality. The full study, published in the journal Scientific Reports, is available online.

“This study shows that even though endocrine disruptors may not affect the life of the exposed fish, it may negatively affect future generations,” said USGS visiting scientist and University of Missouri Assistant Research Professor, Ramji Bhandari. “This is the first step in understanding how endocrine disruptors affect future generations, and more studies are needed to determine what happens in the natural environment.”

There were no apparent reproductive abnormalities in the first two generations of fish, except for two instances of male to female sex reversal in adults of the EE2 exposed generation. Findings show a 30 percent decrease in the fertilization rate of fish two generations after exposure, and a 20 percent reduction after three generations. If those trends continued, the potential for declines in overall population numbers might be expected in future generations. These adverse outcomes, if shown in natural populations, could have negative impacts on fish inhabiting contaminated aquatic environments.

This study examined concentrations of EE2 and BPA that are not expected to be found in most environmental situations. However, concerns remain about the possibility of passing on adverse reproductive effects to future generations at lower levels. At this time, the ability to evaluate mixtures of estrogenic chemicals working jointly is limited. 

The scientists studied BPA and EE2 because they are chemicals of environmental concern and represent different classes of endocrine disrupters. BPA is a chemical used primarily to manufacture polycarbonate plastics and epoxy resins, but is also an additive in other consumer products. Due to extensive use of these products in daily human life, the accumulation of BPA-containing waste in the environment has been a serious concern and a potential threat to public and wildlife health. EE2 is used in oral contraceptives designed for women, and about 16 – 68 percent of each dose is excreted from the body. As a result, EE2 has been found in aquatic environments downstream of wastewater treatment plants.
