| 摘 要： | 于2012—2013年6月和12月采集了内蒙古呼和浩特市大气颗粒物样品,用GC-MS分析测定其中16种PAHs的浓度,并用苯并(a)芘(Ba P)致癌、致突变等效浓度、终身致癌超额危险度和预期寿命损失3个指标评价了内蒙古呼和浩特市大气颗粒物TSP和PM_(10)中PAHs的人群健康风险。结果显示:内蒙古呼和浩特市大气颗粒物TSP和PM_(10)中PAHs对成人、儿童的日均暴露剂量范围分别为0.71×10~(-6)~2.01×10~(-6)、0.45×10~(-6)~1.28×10~(-6)和0.31×10~(-6)~2.41×10~(-6)、0.19×10~(-6)~1.15×10~(-6)mg·kg~(-1)·d~(-1);TSP和PM_(10)中PAHs对成人和儿童的终身致癌超额危险度范围分别为2.21×10~(-6)~6.24×10~(-6)、1.41×10~(-6)~3.97×10~(-6)和0.95×10~(-6)~7.47×10~(-6)、0.60×10~(-6)~4.75×10~(-6),终身致癌超额危险度均处于可接受水平范围内(10-4~10~(-6))。TSP和PM_(10)中PAHs对成人和儿童的预期寿命损失范围分别为13.74~38.78、8.752~24.70和5.88~46.39、3.74~29.54 min。

| Abstract: | During June and December of 2012 and 2013, the atmospheric particulate samples were collected from Hohhot City, Inner Mongolia and among which, 16 kinds of PAHs were detected by GC-MS. Furthermore, health risks to the local population induced by PAHs in TSP and PM10 were assessed by applying carcinogenic, mutagenic equivalents of benzo (a) pyrene (BaP), the average lifelong risk of cancer and loss of life expectancy. The results showed that range of average daily exposure dose of PAHs for adults and children in TSP were 0.73×10-6~2.01×10-6, 0.45×10-6~1.28×10-6 mg·kg-1·d-1, and in PM10 were 0.31×10-6~2.41×10-6, 0.194×10-6~1.15×10-6 mg·kg-1·d-1 respectively. The excess risks for lifelong carcinogenic disease of adults and children were 2.21×10-6~6.24×10-6 and 1.41×10-6~3.97×10-6 in TSP, 0.95×10-6~7.46×10-6 and 0.60×10-6~4.75×10-6 in PM10, which were possibly in the acceptable range levels. The expected loss of life time of PAHs for adults and children in TSP were 13.74~38.78 min, 8.75~24.70 min, and in PM10 were 5.88~46.39 min and 3.74~29.54 min respectively. |
