Meanwhile, disinfection by-products (DBPs) have been proved to be associated with some adverse health effects. The DBP levels were different in drinking water disinfected by different methods and may cause diverse health risks. However, studies in this field and systematic analysis about risk characteristics are limited. We estimated the health risks of DBPs exposure in drinking water through multi-pathways, and systematically analyzed the characteristics of different disinfection methods and influence factors of health risk of DBPs in China. Drinking water samples were collected and analyzed for DBPs from some representative water treatment plants in several typical regions in China. We adopted the additive method to estimate the health risks of DBPs exposure in drinking water through multi-pathways, and used descriptive and hierarchical analysis to understand their characteristics and influence factors. The concentrations of the six DBPs in drinking water ranged from 1.6 μg/L to 13.3 μg/L. The cumulative cancer risk of DBPs exposure through multi-pathways was 8.63 × 10-5. The total HI of DBPs exposure was 1.70 × 10-1. The health risks of DBPs in drinking water disinfected by chlorine dioxide and sodium hypochlorite were lower than by other disinfection methods. The health risk of DBPs in drinking water was dominated by risk through oral and inhalation route. The health risks in wet season were higher than that in dry season. There is no significant difference in health risk for males and females, but children experienced higher health risks than adults. Our study suggested the situation of that a large population experienced the high cancer risk of DBPs in drinking water in typical regions of China. It was suggested that potential higher risk should be concerned, and possible measures could be considered to decrea
