,DDE, Mercury, and Selenium in Biota, Sediments, and Water of the Rio Grande—Rio Bravo Basin, 1965–1ns, with approximately 68% of the highest values detected from Falcon Dam to the mouth of the river. Twenty-six (20%) of the locations with maximum concentrations corresponded to portions of Llano Grande Lake and the Arroyo Colorado. Recent analyses of birds and fish indicate that levels of DDE areExpertise 发表于 2025-3-24 11:58:31
Environmental Chemistry and Toxicology of Polychlorinated ,-Alkanes,al measurements of PCAs are very limited in the U.S. and Canada, and are only slightly more detailed in western Europe. Assuming that reported water concentrations are mainly caused by the short chain (C.--C.) compounds, aquatic organisms may be at risk from exposure to PCAs.

Bioaccumulation of Heavy Metals by Freshwater Insect Larvae,s (Perlodidae), and mayflies (Ephemeridae and Ecdyonuridae) were investigated to determine the degree by which they accumulate or regulate Pb, Zn, Cu, and Cd from sediment and aqueous sources as shown by correlation and regression analyses. For many of the relationships investigated, too few data we
