Lead (Pb) in Arctic char (Salvelinus alpinus) from oligotrophic alpine lakes : Gills versus digestive tract

摘要: We studied Arctic char (Salvelinus alpinus) from two oligotropic high mountain lakes in Northern Tyrol, Austria, that differed pH (5.4 and 7.1) alkalinity (1.3 100.3 µeq L-1). Concentrations of Pb gills, liver, kidney, gut contents stomach were investigated during winter summer to elucidate pathways for uptake these fish. Our study illustrates ratios concentrations gills or intestine (G/S G/l ratios) be a valuable tool evaluating the relative contributions different metal In both sampling periods (winter, summer) appear represent major route pf fish low lakes. However, ice-covered period diet becomes an increasingly important additional source contamination.
