Pollution levels and biomarker responses in zooplankton from three hydrographic regions of southern Brazil: An integrated approach for water quality monitoring

Levels of chemical pollutants [organochlorine pesticides (OCs), current-use pesticides (CUPs), polycyclic aromatic hydrocarbons (PAHs) and trace-metals (Cu, Pb, Zn and Cd)], and biomarkers [metallothioneins (MTs) and lipid peroxidation (LPO)] were assessed in zooplankton of four watersheds belonging to three different hydrographic regions in southern Brazil. Results show that bioaccumulation followed a geographical pattern, as zooplankton from …
