Two clusters were formed by<br>hierarchical analysis of micronuclei percentage (MN), dissolved oxygen (DO),<br>electrical conductivity (EC) and turbidity. The first cluster corresponded to a<br>stream that receives urban untreated sewage, where the highest MN (6.1%)<br>corroborated the physicochemical results (1.90 mg.L‑1 DO, 575.0 μS.cm‑1<br>and 115.6 NTU). The other cluster includes sampling sites with pollutants<br>from agriculture, livestock and industry. Some of them presented high MN<br>even with acceptable values of physicochemical parameters, according to the<br>Brazilian legislation. So for a better quality information on water pollution<br>monitoring it is essential to recognize the variables that affect the biotic<br>components, in a holistic approach of aquatic ecosystem. In this sense the<br>bioassay with T. pallida becomes a useful tool that can be applied in many<br>tropical and subtropical regions, because of its widely distribution.</span></p> ER -
