Abstract
As an environmental endocrine disruptor, atrazine (ATR) can produce serious health damage to humans. This study aimed to assess the exposure and health risks associated with ATR among Chinese adults by analyzing data on ATR concentrations in various environmental media across China. Literatures were retrieved from 5 databases and finally identified 65 eligible studies. The concentrations of ATR in environmental media ranged from 0 to 0.12 mg/kg. The average daily doses (ADD) of ATR for Chinese males and females were estimated at 2.58 × 10−5 mg/kg/d and 2.53 × 10−5 mg/kg/d, respectively. The ADD values did not exceed the reference dose −0.035 mg/kg/d. Sensitivity analysis revealed that body weight and ATR concentrations in various food items such as vegetables, grains, and fruits, along with factors like drinking water intake rate, were the primary influencing factors. Furthermore, the hazard index (HI) values were less than 1 and over 0.32% of cancer risk (CR) values were higher than 10−4, indicating that exposure to ATR could pose a potential risk. The HI and CR values did not exhibit statistically significant differences across genders or among various age groups. This study illustrated that exposed to ATR can pose potential risk to Chinese adults health and dietary intake (including drinking water, and food) was the major pathway by which most humans are exposed to ATR.
