摘要

选用GC-MS分析官厅水库水体中16种多环芳烃(PAHs)的残留情况,并探讨该区域水体PAHs残留特征及其可能的健康风险.研究结果表明,12种PAHs均有不同程度的检出,PAHs总质量浓度为66.20~368.35ng·L-1,与国内其他地区相比,残留水平较低.利用健康风险评价模型对水体中PAHs所致健康风险的评价结果表明,水体中的PAHs的非致癌风险在5.84×10-13~4.90×10-12a-1之间,致癌风险低于2.89×10-9a-1,均低于国际辐射防护委员会推荐水平,目前研究区水体中PAHs类污染物对人体产生的健康风险处于较低水平.

Abstract

Residual characteristics of 16 polycyclic aromatic hydrocarbons (PAHs) in Guanting reservoir and their health risks were studied. The PAHs were analyzed by GC/MS. A total of 12 PAHs were detected in the water samples.∑PAH concentration ranged from 66.20 to 368.35 ng/g. Compared with other areas in China, these PAH residue levels were relatively low. Environmental health risk assessment indicated that non-carcinogenic risk index of water PAH ranged from 5.84×10-13 to 4.90×10-12a-1, cancer risk index of PAH was below 2.89×10-9a-1, below the level recommended by ICRP. Therefore the health risks of PAHs in the water of Guanting reservoir were low.
