| Abstract: |
| Objective Industrial parks emit a large amount of volatile organic compounds VOCs which leads to
atmospheric pollution and human health damage. In this paper typical industrial parks in the upper reaches of the
Yangtze River were used as the study area to investigate the characteristics of VOCs pollution in typical industrial parks and the impact of VOCs pollution on human health risks. Methods Suma canisters were used to carry out continuous
monitoring of VOCs at factory boundary points environmentally sensitive points and urban points in the park. The
samples were analyzed and processed to obtain 108 VOCs substances. The variation characteristics of atmospheric VOCs
were analyzed and the dominant species for ozone O3
generation and secondary organic aerosol contribution were
identified. The non-carcinogenic and carcinogenic risks of VOCs were evaluated using hazard quotient HQ and lifetime
carcinogenic risk Risk
. Results The mean mass concentrations of the total VOCs TVOCs for the first time at factory
boundary points environmentally sensitive points and urban points were 843. 57 μg / m
3
321. 71 μg / m
3
and 149. 50
μg / m
3
respectively. All three sites showed a higher mean concentration of TVOCs at night than in the daytime. The
values of ozone formation potential OFP at factory boundary points environmentally sensitive points and urban points
were 4 507. 25 μg / m
3
1 271. 25 μg / m
3
and 321. 87 μg / m
3
respectively. Methyl methacrylate was the species with the
largest contribution to the OFP value at the enterprise plant boundary point. The values of the secondary organic aerosol
formation potential SOAP at the three sites were 710. 61 μg / m
3
545. 98 μg / m
3
and 209. 83 μg / m
3
respectively.
Aromatic hydrocarbons were the component with the largest contribution to SOAP at these three sites. The average
contribution of SOAP reached 88. 95%. The hazard indices at factory boundary points environmentally sensitive points
and urban points were 0. 31 0. 19 and 0. 08 respectively and there was no non-carcinogenic risk at these three sites.
In the carcinogenic risk evaluation the Risk
values of benzene ethylbenzene and methylene chloride at these three sites
were higher than the EPA acceptable level of 1×10
-6
. Conclusion In conclusion the pollution level of factory boundary
points of enterprises in the park is higher than that of environmentally sensitive points and urban points and higher than
that of other industrial parks. Aromatic hydrocarbons have the highest ability of secondary transformation at each site and
toluene has the highest contribution. These three sites present potential carcinogenic risks to the exposed population and
toluene benzene ethylbenzene and methylene chloride should be prioritized as controlled substances in each region |
