This is a well-studied salmon river with interesting chemistry. The site is part of the European Change Network.US EPA Toxic ContaminantsU.S. Environmental Protection Agency
http://www.epa.gov/ecotox
This is the site for finding what the U.S. Environmental Protection Agency knows about toxicity of environmental contaminants. For example, find the lethal dose of dioxin for the water flea using this site. The site is clunky—it recognizes "dioxin" but not the herbicide "atrazine" (60 million pounds used annually in the United States) or the insecticide "malathion" (16 million pounds used annually in the United States)—you need to know the exact chemical name. You can find the chemical name using a search engine such as google.com.Water ChemistryWisconsin Department of Natural Resources
http://www.dnr.state.wi.us/org/water/fhp/lakes/under/index.htm
This is an excellent source for chemical data from Wisconsin lakes, for phosphorus, nitrogen, chloride, sulfate, sodium, potassium, and carbon dioxide. |
