Research On Health Risk Assessment Of A Venue In Shanghai

Shanghai is China’s important industrial production base,with the development of the industrialization process,the environment problem increasingly prominent in Shanghai industrial zone.People’s health risk problem in industrial zone has caused high attention.Health risk assessment is a method that set risk degree as evaluation index,relate the pollution of the environment and human health,quantitative description of environmental pollution what may cause harm to human body health.It can not only analysed the contaminant risks and potential hazards to the health of different groups,but also can provide reliable basis for industrial zone further planning and development.This paper choosed the venue of the Shanghai industrial area as the research object,used the international general human health risk assessment model to evaluate the field pollutants,in order to have a comprehensive understanding of the field,main pollutant concentration and its potential health risks.The result showed:(1)The average concentration of 93 kinds volatile organic compounds in the atmosphere is 444.77±233.43μg/m~3,including 45.33±25.82μg/m~3carcinogens and 255.75±125.46μg/m~3 non carcinogens.The total concentration of organic matter in the atmosphere in the research site is 3 to 6 times of that in Shanghai city.The concentration of organic pollutants in the concentrations of heavy metals water and the soil surrounding are not higher than the national standard.(2)The average concentration of pollutants in the atmosphere in working days is significantly higher than the weekend.The average concentration in the afternoon is higher than that in the morning,higher than that in the evening.It shows the highest overall performance for the northeast,north higher than the south,east higher than the west distribution characteristics.(3)According to the proportion of organic pollutants in the atmosphere respectively,the field source in order:source 1 for paints,adhesives and coatings,such as organic solvent evaporation source,contribution rate is42.47%;Source 2 emission source for spraying,offset printing and other industrial production,the contribution rate is 19.78%;Source 3 for fuel volatilization and its source,the incomplete combustion products accounted for 11.08%;Source 4 for automotive exhaust emission source,the contribution rate of 6.74%.The field source according to the proportion of organic pollutants in the atmosphere respectively,in order:source 1 for paints,adhesives and coatings,such as organic solvent evaporation source,contribution rate is 42.47%;Source 2 emission source for spraying,offset printing and other industrial production,the contribution rate is 19.78%;Source 3 for fuel volatilization and its source,the incomplete combustion products accounted for11.08%;Source 4 for automotive exhaust emission source,the contribution rate of6.74%.(4)The average non-carcinogenic risk of adult group was 0.94,near the United States environmental protection recommended the critical value 1,suggests that long-term exposure to pollutants concentration of evaluation will have certain potential carcinogenic effects.Adults,the total carcinogenic risk was 4.39e-05,significant health risks associated with cancer.Children groups in the risk of cancer and cancer risk is less than adults,an average of 44.68%of the adult.(5)The health risk though breathing is respectively through the mouth of consumption way and ways of skin contact and inhalation of air particulates way risk value of 104 times,106times and 107 times.Breath way for exposed way of the main pollutants in the atmosphere.(6)The overall performance of the field showed the highest risk at the north and northeast region,followed by the southeast region,northwest and southwest regional health risk value is the lowest.(7)"Working staff"<"resident families"<"working and living personnel",its maximum non cancer risk was 2.09,3.76 and 2.09,respectively,the risk of cancer maximum 8.14 e-05,e-04 e-04 1.46 and1.46.
