In Situ Assessment of the Paraguay River Water, in Brazilian Pantanal, by Means of Micronucleus Assay with Fish and Chemical Analysis

The aim of this research was to assess water quality in a stretch of the Paraguay River within the Brazilian Pantanal by means of a micronucleus assay with fish, and by water and sediment physicochemical analysis. Significant increases ( p >0.05) in the frequency of micronuclei (MN) and micronuc...

Zusammenfassung:	The aim of this research was to assess water quality in a stretch of the Paraguay River within the Brazilian Pantanal by means of a micronucleus assay with fish, and by water and sediment physicochemical analysis. Significant increases ( p >0.05) in the frequency of micronuclei (MN) and micronucleated cells (MNC) occurred in erythrocytes of Pimelodus maculatus and Leporinus friderici at two river sites in the town of Caceres relative to an upstream reference site. The results demonstrate that the Paraguay River water near Caceres has been receiving genotoxic effluents, which may be associated with the presence of chromium, sulfides, oil and grease, and/or other chemicals.
