Studies on mercury content in muscles of fishes from some natural Polish water bodies

Abstract

Total mercury contents were determined in muscles of 16 fish species caught in the river Vistula, its tributaries, and the Łęczyca-Włodawa lakes. All the Vistula fishes examined showed much higher mercury contents compared to those found in fishes from unpolluted waters; mercury contents in many predatory fishes exceed 0.5 mg/kg-1.
