Abstract:
Objective This study was to understand the status of pollution on drinking water, by volatile organic compounds(VOCs),among rural residents living in the basin of Huaihe River. Relationship between the morbidity,morbidity of cancers and VOCs were also explored. Methods 28 villages were chosen from Xuyi,Jinhu,Chuzhou along the Huaihe River,with water samples collected from ditch pond water,shallow wells,deep wells in November-December 2010. VOCs indicators were evaluated according to the Standard Quality GB 5749-2006 for Drinking Water. Results Methylene chloride,chloroform,benzene and carbon tetrachloride were all detected in 76 water samples. The rates of chloroform,benzene,carbon tetrachloride which exceeding the quality standards were 3.95%,21.05% and 22.37%,but no significant differences were found among these three water resources in chloroform,benzene or carbon tetrachloride. Results from the correlation analysis showed that benzene had positive correlation with tumor deaths(r=0.24,P<0.05). Results from the risk assessment on health showed that some chloroform,benzene,carbon tetrachloride products which were related to the risks of cancers were exceeding the acceptable ranges of risk,with the rates as 28.95%,22.37% and 64.47% but with no significant differences among the three water resources(P>0.05). Conclusion Drinking waters for rural residents along the Huaihe River were polluted while VOCs might have related to tumor incidence with potential impact and risk to the health of local residents.
