Kepone In The James River Estuary: Past, Current And Future Trends, Michael A. Unger, George G. Vadas
Kepone In The James River Estuary: Past, Current And Future Trends, Michael A. Unger, George G. Vadas
Reports
In late 1975, a manufacturing facility in Hopewell, VA had not only exposed workers to the chlorinated pesticide, Kepone, but had also severely contaminated the James River estuary. To assess the potential risk to the public, Virginia initiated a finfish-monitoring program in late 1975. Over the next 40 years over 13,000 samples were collected from the James River and Chesapeake Bay and analyzed for Kepone. Kepone production was eventually banned worldwide. The average Kepone concentrations found in most species began falling when the production of Kepone ended, but the averages remained over the action limit of 0.3 mgkg-1 until …
Acute Effect Of Free Chlorine On Selected Estuarine Invertebrates And Vertebrates : Final Report, Morris H. Roberts, Robert J. Diaz
Acute Effect Of Free Chlorine On Selected Estuarine Invertebrates And Vertebrates : Final Report, Morris H. Roberts, Robert J. Diaz
Reports
The objective of this project was to determine acute toxic effects of chlorine on selected estuarine organisms found adjacent to the projected outfall of a sewage treatment plant in the lower York River. The test species specified under contract were ovster (Crassostrea virginica) and clam (Mercenaria mercenaria) larvae, Acartia tonsa (a dominant copepod), and the fishes, menhaden (Brcvoortia tyranus), pipefish (Svngnathus fuscus), blennies (Hypsoplennius hentzi) and sheepshead minnow (Cyprinodon variegatus). The parameter of interest in the tests was mortality when the animals were exposed to a constant level of chlorine for a 48 or 96 hr period.
