Acute ecotoxicity and genotoxicity assessment of two wastewater treatment units.

Water contamination by discharge of untreated or poorly treated wastewater into water bodies is a current issue that may cause harm to humans. Water quality assessment targets general parameters, which often misleads to underestimation of their implication in the environment. Acute and genotoxicity assays using Daphnia magna is a reliable tool for testing deleterious effects of wastewater exposure.
