Tissue distribution of metals in striped dolphins (Stenella coeruleoalba) from the Apulian coasts, southern Italy. 总被引:4,自引:0,他引:4
Tissue distributions of metals (mercury, lead, cadmium, zinc, copper, iron, manganese) were determined in six specimens of striped dolphins (Stenella coeruleoalba, Meyen) stranded on the Apulian coasts (Southern Italy) between February and June 1987. Methyl mercury and selenium were also determined in the liver samples. The liver accumulated the highest concentrations of metals, except for cadmium and chromium. Metal levels were higher than those found in dolphins living in the Atlantic, but lower than those recorded in the same species from the French Mediterranean coasts. Necroscopic surveys found that all specimens were affected by haemorrhagic gastritis, but the cause was not clear. While it was not possible to related the death of dolphins to a specific cause, or to contaminants, the accumulation of metals is likely to contribute to the health of the organism and represents a risk factor for dolphins. 相似文献

In fiscal year 1982, the U S Geological Survey began an interdisciplinary research thrust entitled Toxic Waste-Groundwater
Contamination Program The objective of the thrust was to provide earth sciences information necessary to evaluate and mitigate
existing groundwater contamination problems resulting from the planned or inadvertant disposal of wastes and from certain
land-use practices, and to improve future waste disposal and land-use practices The program supports process-oriented and
interdisciplinary field research, and regional groundwater quality studies This article provides an overview of the current
(Fiscal Year 1985) activities of the Toxic Waste Program 相似文献
