Abstract
The method of health risk assessment was used to evaluate the health risks caused by SO2 pollution in the urban area of Suzhou. SO2 is a non-carcinogenic chemical. The health risk of the population was calculated by the method of non-carcinogenic health risk assessment, and the results could provide the theoretical basis for the evaluation of environmental pollution and occupational hazards. According to the monitoring data of SO2 concentration in the atmosphere of Suzhou city and the respiratory disease mortality rate of the population from 1993 to 2002, we conduct statistical analysis and calculations. The results showed that there was a positive correlation between the mortality of respiratory diseases and the daily exposure dose of SO2 in the atmosphere. In 2002, the annual health risk caused by SO2 pollution in the atmosphere was 0.0078 * 10-6. Compared with the respiratory disease and lung cancer mortality, the mortality rate caused by SO2 is very small in respiratory diseases and lung cancer deaths. Therefore, it can be considered that the health hazard of SO2 pollution is relatively small. According to the analysis of the physical examination data of workers exposed to SO2, the results showed that the health risk of workers exposed to SO2 should not be ignored. Labor protection needs to be strengthened.
