Macroinvertebrados bentônicos como bioindicares da qualidade da água em três nascentes do Complexo Parque do Sabiá, Uberlândia, Minas Gerais.

Abstract

This study was realized in the Complexo Parque do Sabiá, located in Uberlândia city, Minas Gerais, Brazil. The main goals were to analyze the water quality in three park springs, to compare the benthic macroinvertebrates community, to analyze the chemical physical parameters of water and to compare the springs evaluated. Benthic macroinvertebrates were used as bioindicators to reach these objectives. The organisms were collected with "D" net and were preserved with 70% alcohol. The samples were taken to the laboratory where they were analyzed with an esteriomicroscope. The results showed a significant percentage of Chironomidae in all points sampling, and two of those points present low macroinvertebrates diversity, indicating disturbed environments. The conclusions were that the three sources have springs of environmental impact, and the second spring P2 was less affected by anthropogenic disturbances.
