A relação entre o saneamento ambiental e a saúde da população na Sub-Bacia Hidrográfica do Rio Tocantins, no município de Imperatriz-MA

Abstract

In urban areas, irregular water supply, ineffective solid waste management and domestic effluent treatment policies are factors that cause pathologies such as diseases related to inadequate sanitation (IADRs). This research aimed to assess the incidence of IADRs related to the lack of environmental sanitation in the Riacho Bacuri sub-basin between 2010 and 2020. It also analyzed the association between the environmental sanitation conditions of households according to the Demographic Census (2010) and the incidence cases of IADRs provided by the Municipal Health Department. To do this, geostatistical analysis was carried out using the Moran index (LISA) and the GeoDA software, and the rapid assessment protocol (PAR) was used to analyze the landscape.  According to the results, over the years 2010 to 2022, the Bacuri, Vila Nova, Vila Lobão and Redenção neighborhoods had the highest averages of diseases related to lack of environmental sanitation. In summary, there is a need for universal basic sanitation, environmental education actions and improvements in housing conditions in the municipality of Imperatriz.
