Insights to estimate exposure to regulated and non-regulated disinfection by-products in drinking water

P. E. Redondo-hasselerharm, D. Cserbik, et al.

This study conducted by Paula E. Redondo-Hasselerharm and colleagues uncovers significant human exposure to disinfection by-products in drinking water. Through thorough analysis of tap, bottled, and filtered water, as well as urine samples, the research reveals high levels of DBPs in tap water and a notable link between urine concentrations and drinking habits. Explore these groundbreaking insights into public health risks associated with water consumption.

Abstract

This study investigated human exposure to disinfection by-products (DBPs) in drinking water. Tap water, bottled water, and filtered water samples, along with urine samples from Barcelona residents, were analyzed for various DBPs. Statistical models (multivariate linear regression and machine learning) predicted non-regulated DBPs based on regulated THMs. Results showed high DBP presence in tap water, reduced levels after filtration, and a correlation between urinary TCAA and drinking water intake. The findings offer insights for DBP exposure assessment in epidemiological studies.
