Commercial formulation containing quinclorac and metsulfuron-methyl herbicides inhibit acetylcholinesterase and induce biochemical alterations in tissues of Leporinus obtusidens

Ecotoxicology and Environmental Safety, 2011
The effects of commercial formulation containing quinclorac and metsulfuron-methyl herbicides on acetylcholinesterase (AChE), antioxidant profile and metabolic parameters in teleost fish (Leporinus obtusidens) were studied. The fish were exposed during 90 days to commercial formulation containing quinclorac (204 μg L(-1)) and metsulfuron-methyl (5.8 μg

Análise citogenética de Leporinus cf. obtusidens e Leporellus vittatus (Characiformes, Anostomidae) da bacia do rio São Francisco

Semina: Ciências Biológicas e da Saúde, 2018
Anostomidae é uma família altamente especiosa entre os Characiformes, compreendendo 156 espécies válidas, as quais estão distribuídas na região Neotropical. Estudos citogenéticos com anostomídeos revelam que sua estrutura cariotípica é altamente conservada, com variações quanto a presença de cromossomos sexuais.

Moving beyond classical markers of water quality: detection of enteric viruses and genotoxicity in water of the Sinos River

Brazilian Journal of Biology
It is well recognized that the classical biological and chemical markers of environmental pollution do not necessarily indicate the presence or absence of emerging threats to public health, such as waterborne viruses and genotoxicants.
