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.
