Effects of PCBs on the Electrolyte Balance in Blood of Crucian Carp
多氯联苯对鲫鱼血液电解质的影响

The effects of PCBs exposure on the concentrations of electrolytes(sodium, potassium, calcium, magnesium) in blood plasma of the cruciancarp were examined. In the Crucian Carp, theplasma sodium concentration increased significantly durging the exposure to an aqueous PCBssolution and the plasma sodium concentration increased as the concentration of PCBs increased.The plasma concentration of potassium decreasedduring the exposure to PCBs, and the plasmapotassium concentration decreased as the concentration of PCBs increased. The Plasma concentrations of calcium and magnesium did not show anyclear patterns.
