A formação de Trihalometanos no tratamento de água e seus potenciais impactos na saúde: uma abordagem bibliográfica

Abstract

Trihalomethanes (THMs) are byproducts that arise during the water disinfection process with chlorine. They form when chlorine, used to eliminate contaminants, reacts with the organic matter present in the water. This review article explores in detail how THMs are generated, the risks they may pose to human health, and the different strategies developed to reduce their presence in water supply systems. It also highlights the identification of conditions that favor the creation of these compounds and the types of organic matter that contribute most to this. Additionally, new technologies that have shown efficiency in removing THMs, such as advanced oxidation processes and filtration, are presented. It emphasizes the need for a comprehensive approach to tackle the challenge of THMs, which combines stricter regulations, constant monitoring, and technological innovations. The aim is to provide important information to ensure that the water supplied to the population meets safety and quality standards, protecting public health and reducing the risks associated with exposure to these compounds. In this way, the article's approach seeks not only to alert about the potential dangers of THMs but also to highlight practical and effective solutions to reduce their formation and presence in drinking water.
