متن کاملComparison of Mercury Distribution Between Liver and Musc - A Biomonitoring of Fish from Lightly and Heavily Contaminated Localities
Tissue samples from 1,117 fish of 25 species were collected from 1991 through 1996 at 13 locations along the River Elbe. The principal indicator species were perch (Perca fluviatilis) (n=118), chub (Leuciscus cephalus L.) (n=113) and roach (Rutilus rutilus) (n=138). Mercury (Hg) concentrations in muscle and liver were determined by atomic absorption spectrometry. The liver/muscle index in three...
متن کاملTemporal and spatial trends of PCBs, DDTs, HCHs, and HCB in Swedish marine biota 1969–2012
In the 1960s, the Baltic Sea was severely polluted by organic contaminants such as PCBs, HCHs, HCB, and DDTs. Elevated concentrations caused severe adverse effects in Baltic biota. Since then, these substances have been monitored temporally and spatially in Baltic biota, primarily in herring (Clupea harengus) and in guillemot (Uria aalge) egg, but also in cod (Gadus morhua), perch (Perca fluvia...
متن کاملHigh summer concentrations of mercury in big perch (Perca fluviatilis L) from the Tvärminne archipelago (SW Finland) and Nåtö (Aland Islands) Baltic sea.
