- Abstract:
-
In order to insure the safety of water used by the residents along the Xihe River Area, a preliminary assessment of the health risk caused by POCPs was performed by CSOIL Model of Holland RIVM. Results showed that the total level of 6 PCB(∑PCBs) in groundwater ranged from 0.08 to 5.89 ng/L, 9 OCP(∑OCPs) ranged from 0.17 to 21.2 ng/L, which were below the concentration limits in the Standards for Drinking Water Quality(GB5749-2006). Crop ingestion and drinking water are the most important exposure pathways in health risk assessment of groundwater. The total average indiviual annual health risks caused by crop ingestion, drinking water, inhalation and demal ingestion in the bathing were 1.63×10-7~6.21×10-6 per year. Health risks at 9 sampling points followed the order: Zhaijia>Fuguan>Shuangshu>Qianmiao>Tuxi >Dawula >Huanglatuo >Qianyu >Dapan. Though risks of PAHs at all sampling points were less than the recommended maximum acceptable value of the International Commission on Radiological Protection(ICRP), the health risks could not be ignored.
