Diagnóstico ambiental de um afluente do córrego paragem, situado em área de unidade de conservação de proteção integral, Dourados - MS

Abstract

The Municipal Natural Park of Paragem (PNMP) is an integral protection conservation unit and aims at the conservation and recovery of ecosystems. However, it receives direct anthropic influence that can affect its vegetation and the balance of the aquatic community. Therefore, the objective of this work was to analyze the vegetation index and diagnose the water quality of a tributary of Córrego Paragem located in the PNMP. Thus, the Green Leaf Index, physical-chemical and microbiological parameters of the water were analyzed, as well as the performance of ecotoxicological tests at three trophic levels. In addition to these, the genotoxic effect of water in a piscean model was also evaluated. As a result, a low incidence of vegetation and degradation of water quality in the park was observed, identified by the existence of microbial contamination, toxicity in primary producers and genetic damage in fish. Therefore, measures are needed in these park areas to favor the recovery and conservation of these environmental resources.
