www.rsc.org — Environmental contaminant and biomarker monitoring data from major U.S. river basins were summarized for black bass (Micropterus spp.) and common carp (Cyprinus carpio) sampled over a nine year period. Cumulative frequency distributions revealed taxon differences for many organochlorine residue concentrations, elemental contaminant concentrations, More...

www.umesc.usgs.gov — Research at the Upper Midwest Environmental Center, which gathered detailed observations on tree swallow nesting success and contaminant concentrations in 1998-2000, to guide EPA and the U.S. Fish and Wildlife Service in effectively managing the risk of chemical contaminants to wildlife and the environment.

wfrc.usgs.gov — Mercury contamination from historic gold mining operations is widespread in many rivers, lakes, and reservoirs on the western slopes of the Sierra Nevada. A multidisciplinary investigation by USGS is attempting to better understand mercury dynamics and to identify hot spots within Camp Far West Reservoir in order to determine if remediation More...

tinyurl.com — Organochlorine pesticide and total polychlorinated biphenyl (PCB) concentrations were measured in largemouth bass from the Tombigbee River near a former DDT manufacturing facility at McIntosh, Alabama. Concentrations of DDT isomers in McIntosh bass remained unchanged from 1974 to 2004 and were four times greater than contemporary concentrations More...

wfrc.usgs.gov — The objective of this project is to compile existing information into a format that will allow endangered species recovery planners to consider risks posed by various sources and types of water pollution. Identification of sources of pollution should include point- and nonpoint-sources. it is unlikely that all sources of pollution in all water More...

fresc.usgs.gov — The river otter (Lontra canadensis) is a top predator of most aquatic food chains. The goal of this study is to further evaluate the relationship among the contaminants and observed reproductive organ hypoplasia in young male river otters, their occurrence, and mode of action or mechanism that causes hypoplasia with a larger series of data from More...

wfrc.usgs.gov — There are approximately 500,000 abandoned mines in the western US. Collectively, these mines pollute rivers, streams, and western reservoirs with millions of tons of metals annually that degrade aquatic habitat and water used by humans for drinking, recreation, and irrigation. However, there is great potential in decreasing or eliminating the flow More...
