A utilização de macroinvertebrados bentônicos como bioindicadores da qualidade das águas: o biomonitoramento como uma chave para a restauração de ambientes aquáticos degradados por ações antrópicas.

Abstract

The diverse impacts on the aquatic environments caused by the different activities of social purpose (e.g. human waste, hydropower plant construction, industrial use of substrate, among others) have the potential to modify both composition and the dynamics middle one, this way, the use of only one method for verification of this field becomes inadequate to address all of the information imposed on the study on the restoration of degraded areas by human actions. Thus, the biomonitoring, is related to an alternative approach to the complement the traditional study by virtue of entry of new data in research, given that this option can capture different areas not dealt in sketch unexceptional. In this sense, the aim of the present study is to evaluate, based on a literature review, the ecological implications regarding the use of benthic macroinvertebrates as bioindicators of pollutants originated from anthropic activities in aquatic environments. For that purpose, methodology of this study will be based in an exploratory and descriptive character, given that central the discussion involves the bioindication as a supplementary tool for assessing and classifying from water quality. Regarding the delineation was characterized as a literature search. In general, the fifty-seven articles found at platform Scielo only seven were located in Northeast Brazil. Nevertheless, is evident out that these demonstrate other alternatives regarding the use of benthic macroinvertebrates. It is assumed, therefore, that this region still use the traditional verification as the primary means of data collection.
