| 摘 要： | 用个人采样装置测定了北京海淀区交警夏季多环芳烃(PAHs)暴露.以16种PAHs之和计,气态和颗粒物吸附态的平均暴露浓度分别为(1 520±759)ng/m3和(148±118)ng/m3,显著高于定点对照测定结果气态(588±228)ng/m3,颗粒物吸附态(52±50)ng/m3].交警和对照点具有致癌作用的高环化合物总暴露浓度分别是(14.9±5.9)ng/m3和(6.7±3.6)ng/m3,主要来自颗粒物吸附态暴露.暴露量具有显著的日波动特征,主要受温度和湿度影响.气态浓度与湿度正相关,与温度负相关,颗粒物吸附态浓度则与温度和湿度看不到显著相关关系.

| Abstract: | Personal samplers were used for measurement of exposure of traffic policeman in Beijing in summer 2004.The total exposed concentrations were(1 520±759) ng/m3 and(148±118) ng/m3 for gaseous and particle phases PAHs,which were significantly higher than those measured at control site away from the street.The total exposed concentration of carcinogenic PAHs were(14.9±5.9) ng/m3 for policeman and(6.7±3.6) ng/m3 for control,which were primarily contributed by particle phase PAHs.The daily variation of the exposure was under influences of temperature and humidity.Positive correlation between gaseous PAHs and humidity and negative correlations between both gaseous and particle PAHs and temperature were revealed. |
