Trend analysis of the load and concentration of physical, chemical and biological parameters in the Verde River Basin

Abstract: The estimation of loads of pollutants is of crucial interest to identify the level of water quality, understand the processes and identify the sources of pollution. The aim of this study was to calculate time trends of loads and concentrations of eleven physical, chemical and biological parameters, in nine quality monitoring stations of the Verde River Basin from 2008 to 2014. The time series analysis was performed with different tests. First, with the verification of autocorrelation of the time series using t… Show more

“…Tal configuração é importante, uma vez que a qualidade da água tende a piorar à medida que se aumentam as contribuições de cargas poluidoras. No Brasil, o lançamento de efluentes domésticos sem tratamento se caracteriza como a principal fonte de poluição dos corpos hídricos (Calazans et al, 2018a;Calazans et al, 2018b;Costa et al, 2017;Fraga et al, 2020;Oliveira et al, 2018;Pinto et al, 2017;Soares et al, 2020;Trindade et al, 2017;Vargas et al, 2018).…”

“…Many studies regarding water quality have been presented with the objective of evaluating the extension of impacts in quali-quantitative aspects of hydrographic basins as consequences of anthropization (Trindade et al, 2016;Pinto et al, 2017;Gebler et al, 2018). However, although there may be much data available, this information is often disorganized and scattered in different institutions and public agencies.…”
