| 摘 要： | 在我国某肺癌高发区采集大气颗粒物样品,测定了其中16种多环芳烃(PAHs)的浓度,并收集人群的日饮食样品,以苯并(a)芘(Bap)为代表,计算人群通过空气和饮食的Bap日暴露量.用ICP-MS测定饮食中14种微量元素的日摄入量.结果表明,该地区室内空气PAHs污染显著高于室外,且毒性强的5、6环PAHs所占比例高于对照点.高发区Bap日暴露总量均值为3.758μg/d,比对照点(0.257μg/d)高近14倍.高发区有毒重金属Cd和Tl日摄入量显著高于对照点; 高发区元素Se日摄入量显著低于对照点,且该地区人群从环境中摄入Se严重不足;Fe、Cu和Zn的日饮食摄入量明显低于营养元素日摄入量推荐值(RDA). |
| 关 键 词： | 多环芳烃 微量元素 日暴露量 肺癌 |

| Abstract: | Air samples were collected to determine the concentrations of the 16 polycyclic aromatic hydrocarbons(PAHs) in some high lung cancer rate area of our country.Total 24 h food and drinking water of the subjects were collected.Daily total exposure to Bap of local people was analyzed through the approaches of air and food.Concentrations of 14 trace elements were determined using ICP-MS and daily total exposure of each element was calculated.The experiment results showed that the PAHs pollution was more serious ... |
| Keywords: | polycyclic aromatic hydrocarbons (PAHs) trace element daily total exposure lung cancer |
