Análise da qualidade da água da lagoa da salina - Morada Nova/CE

Abstract

Population increase, coupled with the urbanization process, has caused a reduction in water quantity and quality, leading to loss of biodiversity, increased disease and compromising the predominant uses of water, such as irrigation, leisure and fishing. Given this situation, it is necessary to evaluate water quality through parameters that serve as indicators of the actual state of the water body. In this sense, the objective of this work is to evaluate the water quality of Lagoa da Salina, monitoring the physicochemical, biochemical and microbiological attributes of water and to determine the Trophic State Index (EIT). As a methodology, we opted for a qualitative research, starting with a literature review on the subject, followed by data collection, laboratory tests and analysis of results. Through the analyzes performed in this work, it was found that the water quality of the saline lagoon is not in good condition, because for most parameters the results are outside the limits established by CONAMA Resolution No. 357/2005.
