PARAMETERS IN THE STATE OF BAHIA
Basic Sanitation, Water Quality, Environmental Health and Human Health.
Concern with the assessment and implementation of environmental protection has been gaining space and discussions for the awareness of society and the need for effective maintenance of ecosystems. This study addresses issues of public and environmental health and demonstrates the importance of water quality analysis of hydrographic regions of the state of Bahia and their health micro-regions. The objective is to make a correlation between the occurrence of waterborne diseases of the state and the indicators of physical, chemical and microbiological parameters of water following the resolution of the National Environment Council - CONAMA 357/2005. Health data were acquired through the Hospital Information System (SIH / SUS) of the Health Portal of the Department of Informatics of the Unified Health System (DATASUS), where notifications were used according to the system of hospitalizations of parasitic and infectious diseases through the direct and indirect contact of contaminated water. Pearson's correlation test was performed between Waterborne Diseases and Water Quality Index in 28 health microregions and 25 hydrographic regions correlating with 13 diseases provided by DATA SUS. After evaluation of the indicators, it was observed that several microregions showed direct relationships with water quality variables, such as total nitrogen, dissolved oxygen, total phosphorus and temperature, related to amoebiasis, schistosomiasis, viral hepatitis, cholera and parasitic infectious diseases. , mainly in the Porto Seguro, Jacobina, Santo Antonio de Jesus, Barreiras, Juazeiro, Ilhéus, Itabuna and Valença microregions. By understanding the results, we can collaborate on future public health interventions to improve water quality, thereby reducing the disease transmission chain.
