A ECOTOXICOLOGIA COMO FERRAMENTA NO BIOMONITORAMENTO DE ECOSSISTEMAS AQUÁTICOS
Ecotoxicology is a science created to solve problems with water contamination by toxic compounds. The analytical framework employed is capable of predicting biological responses to the toxicity of chemical compounds through concentration-effect and concentration-response curves, and also enables evaluating the ecotoxicity of disturbed environments ...
