Water-supply potential of major streams and the upper Floridan Aquifer in the vicinity of Savannah, Georgia Water-supply potential of major streams and the upper Floridan Aquifer in the vicinity of Savannah, Georgia

Long-term pumping from the Upper Floridan aquifer in the Savannah, Georgia, area has lowered ground-water levels, resulting in increased salinity of ground water by seawater encroachment at Hilton Head Island, S.C., and by saltwater intrusion at Brunswick, Ga. Increased pumpage could cause further salinization of the ground-water resources. The Savannah and Ogeechee Rivers can be...

An evaluation of a genotoxicity assay with liver s9 for activation and luminescent bacteria for detection An evaluation of a genotoxicity assay with liver s9 for activation and luminescent bacteria for detection

A new short-term in vitro genotoxicity assay with marine bioluminescent bacteria was evaluated for sensitivity and cost. Known under the trade name of Mutatox™, this assay is a simple and rapid screening tool that detects DNA-damaging substances (genotoxins) by measuring light output from an isolated dark mutant strain of the luminescent bacterium Photobacterium phosphoreum. A positive...

Lake acidity and mercury content of fish in Darwin National Reserve, Russia Lake acidity and mercury content of fish in Darwin National Reserve, Russia

Darwin National Reserve is a protected natural area on the north-west shore of the Rybinsk Reservoir, 350 km north of Moscow. In June 1989, six lakes in the Reserve and the reservoir were surveyed to assess lake acidity and the mercury content of perch, Perca fluviatilis. Five were seepage lakes with no permanent inlets or outlets and one was a drainage lake with both an inlet and an...

The use of tumors in wild populations of fish to assess ecosystem health The use of tumors in wild populations of fish to assess ecosystem health

Evidence has linked toxicants in aquatic systems with cancer in fish and population level effects on species. Thus some types of tumors may be useful monitors of ecosystem health, at least as affected by genotoxins and promoters. However, tumors caused by purely genetic mechanisms or by virus would not be good indicators. Only neoplasms which have chemicals as a portion of their etiology...
