Análise das condições físicas, químicas e microbiológicas do Rio Cuiabá

Abstract

The packaging is variable, depending on the location and conditions of its origin. The startup of natural and artificial changes from a refrigerant that causes chemical, physical and biological changes in water is a major source of contamination. The protection of water resources is essential to ensure the quality of the soil and the ecological balance of the planet. (SEMA-MT) in May 2017. The study was developed in the Cuiabá River, which is located in the hydrographic region of Paraguay and is considered as an important water body for the state of Mato Grosso, as well as for the Pantanal. Data analysis was used at all Water Quality Levels (IQA), which represents an average of several variables. There was no relation of a previous or optimal index for the seasons. The nearest value is an index at station CBA134 (P1) with 43. This index is characterized as poor, since the variables OD, Escherichia coli, total phosphorus and turbidity are higher than the limit allowed in legislation. In the IQA scale for the quality of water bodies classified as bad, the range is from 50 to 26. In all the samples of this study, the occurrences of a bad index were recorded. In CBA134 (P1), four indices were found in the ruins, in the months: January 2011, February 2014 and 2017 and November 2017. These indices are concerned, since this station is a first of the Cuiabá river, that is, in a less anthropized area. In the next station (CBA269 P2) there was no occurrence of bad index. The CBA406 station (P3) has two bad index occurrences. As in the first season, the month of February 2014 was also characterized as bad, as well as the month of February 2016. Station CBA671 (P4) was also called bad index occurrences. In February 2012, the index was 45, where an OD variable was the only variable that settled at the borders established by Conama Resolution 357/2005, with 4.44 mg/L O2.
