Abstract:
Objective Using a health risk assessment method to quantitatively describe the situation of chloroform and carbon tetrachloride in drinking water in Lu'an city, and to assess their potential risks to human health.
Methods Setting water quality monitoring sites was based on the aggregation of the population in Lu'an City. Water samples were collected and detected in 2014.
Results The average concentration of chloroform and carbon tetrachloride in drinking water was 0.035mg/L and 0.0002mg/L, respectively, and the carcinogenic risk value was 59.3×10-6 and 1.10×10-6, respectively.The health risk index for chloroform and carbon tetrachloride in drinking water was 0.1912/a and 0.0122/a, respectively.
Conclusion The carcinogenic and non-carcinogenic risk induced by chloroform and carbon tetrachloride through drinking water was in the acceptable value recommend by US EPA.
