CONTENT ANALYSIS ON THE PROCESS OF EUTROPHIZATION OF WATER BODIES FOR THE UNDERSTANDING ABOUT WATER TRANSMITTED DISEASES

Abstract

Eutrophication is a process resulting from the bioaccumulation of organic matter that promotes the increase of macrophytes in an uncontrolled manner, causing changes in the color and aging of the water body. To analyze the eutrophication process in water bodies for the understanding about waterborne diseases through a qualitative content analysis. This is a qualitative content analysis of the documentary type proposed by Bardin (2011), which is based on the organization of data by categories. The study was based on the research of Silva and Fonseca (2016), organized into three categories involving: urban occupation, the eutrophication problem, water quality aspects, and the need for quality and quantity sewage treatment over a fi ve-year period. It was observed that urbanization, lack of environmental sanitation, high concentrations of phosphorus and nitrogen favor the eutrophication of waters. When these waters are classifi ed as hypereutrophic, attention should be paid to the possibility of the gradual disappearance of the water resource. These problems cause the death of fi sh and crustaceans, socioeconomic problems in the fi sh market and tourism. Microbiological and physical-chemical analyses are indispensable for control. The conclusion is that there are several parameters that are associated with the quality of the water, which can become a reservoir for waterborne diseases. Furthermore, producing drinking water is not easy and demands high investments, however, a good and constant treatment of water and sewage is essential.
