The Research on Health Risk Valuation of a BETX-Contaminated Site
According to the technical standards for soil monitoring,the latest standards of soil environmental quality and the technical guidelines for HJ25 series,conduct BETX detection and health risk assessment in various functional areas of an industrial pollution site in Anqing,the following conclusions are drawn:①Compared with the standard value 1mg/kg,the rate of exceeding the standard is 100%,and exceeded multiples range from 1.39 to 20.7;②Based on health risk valuation of population,it was found that the carcinogenic risk index of benzene was distributed between 1.52×10-7 and 1.38×10-6,which only exceeds the cancer risk threshold of 10-6 in the production area.Meanwhile,the non carcinogenic risk quotient is distributed between 9.92×10-3 and 9.01×10-2,all of which have not exceeded the non carcinogenic risk threshold of 1.③Because the site risk Assessment Guide is lack of relevant parameters,resulting in low risk level calculation results,which is at the same point of benzene even exceeding the limit,there is no cause of cancer risk.
