Abstract

THMs Exposure Risk Assessment and Disease Burden of Bladder Cancer in Drinking-Water of Some Cities in China

As a result, four types of THMs are all detected in the drinking water of some cities in China, including chloroform (TCM), bromoform (TBM), Di Bromo Chloro Methane (DBCM), and Bromodichloromethane (BDCM). The health risk of TCM, TBM, DCBM, and DBCM is 1.40 × 10^-6, 4.3 × 10^-7, 7.63 × 10^-6, and 7.93 × 10^-6, respectively. And the hazard index (HI) values of TCM, TBM, DCBM and DBCM are 0.023, 0.0027, 0.0061, and 0.0047, respectively. The PAF of bladder cancer exposed to the THMs is 0.017% in all cities referred to in this study. Combining with the PAF, the corresponding disease burden attributed to the exposure of THMs is 1.89/100,000, indicating that it may cause a certain disease burden.
