As atividades antrópicas na modulação da qualidade de água do rio Guamá, em São Miguel do Guamá, Pará.

Abstract

The objective of the present study is to analyze, through the analysis of the main components, the correlation between the physical parameters of water quality and the discharge of waste from anthropic activities in the Guamá River, in. Thus, the chemical parameters were used: pH, Dissolved Oxygen, Electrical Conductivity, Dissolved Total Solids, Water Temperature and Turbidity. The collection of water was done at three points characterized by the dumping of waste from activities located on the banks of the river, PA (boom) red ceremic industry, PB (center) domestic sewage and PC (downstream) logging activity, and through the method of analysis of the main components were correlated and analyzed on a time scale of 6 monthly collections between the years 2015 and 2017. The research revealed that the parameters present significant statistical differences between the annual sample series, and not significant between the spatial scale by points collection, and verified in the SPC strong correlation in months of collection with low precipitation regime in the region.
