Research on the Health Risk Assessment of Chemical Pollutants in Reclaimed Water Used for Streets Watering
再生水道路降尘化学污染物的健康风险评价研究

It is the first time for this research to utilize the method of health risk assessment. Combining with Beijing reclaimed water project, the exposure dose level and health risk to contact people are investigated and studied. The risk assessment model is built, and the exposure parameters of occupational workers and common people are provided, when reclaimed water was used for streets watering. The health risks of 19 main chemical pollutants in reclaimed water are evaluated quantificationally. The results show that the total risk caused by carcinogens is 8.47×10-6 for occupational workers and 3.78×10-6 for common people.
