Land use influence on ~137Cs levels in perch

摘要

The environmental influence of Chernobyl-derived ~137Cs levels in perch (Perca fuviatilis L.) and roach (Rutilus rutilus L.) was revealed using partial least-squares regression (PLS). The 53 environmental predictors used describe land use in catchment areas, various catchment area and lake characteristics, lake water chemistry, and fish stock composition. The study showed a profound effect of land use on the ~137Cs levels in fish.
