title: [Population exposure to HCH in Tianjin area].
abstract: The population exposure to HCH in Tianjin area is estimated based on field data on media concentration and other data from the literature. A multimedia /multipathway human exposure model is employed to calculate the population' s Chronic Daily Intake (CDI) of HCH. The population's lifetime CDI was 0.05microg x (kg x d)-1, and the daily exposures of child, youth and adult were 0.10, 0.06, and 0.04microg x (kg x d)-1, respectively. The result indicates that diet exposure was the most important route, accounting for 87% of total dose. Respiration ranked second and contributed 5% - 10% of the total dose.
