Increases in industrial mercury (Hg) emissions in recent years have led many researchers to
believe that Hg from the atmosphere constitutes a main source of Hg to aquatic biota in the …

The effects of sublethal waterborne Zn2+ (150 µ g l-1= 2.3 µ mol l-1) on the kinetics of
unidirectional Ca2+ influx were studied in juvenile freshwater rainbow trout during chronic …

The European eel (Anguilla anguilla L.) was exposed to diesel oil water-soluble fraction
(DWSF) and gasoline water-soluble fraction (GWSF). The potential of these fractions to …
