| 摘 要： | 2011年－2014年对邵阳城区不同功能区降尘的铅镉污染开展监测及健康风险评价，监测结果表明，邵阳市城区铅、镉的年均含量分别为178.34 mg · kg－1、2.12 mg · kg－1，平均富集系数分别为5.6、16.6。健康风险评价结果表明，降尘中铅的非致癌风险大于镉，儿童的非致癌风险远高于成年女性和成年男性，手－口途径非致癌风险远高于其他两种途径，铅、镉的总非致癌风险人群危害较小，镉呼吸途径不具有致癌风险。

| Abstract: | The monitoring and health risk assessment for the contamination of Pb , Cd in atmospheric deposition in different function area of Shaoyang from 2011 to 2014 were carried out.Result of monitoring showed the annual average contents of Pb , Cd in urban area of Shaoyang were 178.34 mg· kg -1,2.12 mg· kg-1, average enrichment coefficient of Pb, Cd were 5.6,16.6. Health risk assessment showed that the non-cancer hazard index of Pb is higher than Cd , children is much higher than adult fe-male and adult male, hand-mouth ingestion was much higher than other two ways.The non-cancer hazard index and the cancer hazard index were both lower than their threshold values, suggestion that will not harm the health. |
