Abstract

Atmospheric concentrations of volatile, halogenated hydrocarbons (VHH) can be correlated with intensity of industrial or commercial activities and with demographic density. Measurements of VHHs were performed in Turin, Italy. The VHH indoor/outdoor contamination ratio was calculated, and VHH blood concentrations were measured during 1 yr in Turin, Italy. The results showed a typical primary pollutant trend: 18.1 micrograms/m3 during winter and 12.02 micrograms/m3 during summer. During the winter, the VHH indoor/outdoor contamination ratio showed a greater indoor presence (p = .0006) and a higher VHH blood concentration (0.71 vs. 0.22 micrograms/l). The indoor and outdoor atmospheric VHH concentrations provide the major sources of human daily intake, especially during winter.

摘要

大气中挥发性卤代烃（VHH）的浓度与工业或商业活动强度以及人口密度相关。在意大利都灵对VHH进行了测量。计算了VHH的室内/室外污染率，并在意大利都灵进行了为期1年的VHH血液浓度测量。结果显示出典型的一次污染物趋势：冬季为18.1微克/立方米，夏季为12.02微克/立方米。在冬季，VHH的室内/室外污染率显示室内存在量更大（p = 0.0006），且VHH血液浓度更高（0.71微克/升对0.22微克/升）。室内和室外大气中的VHH浓度是人类日常摄入量的主要来源，尤其是在冬季。
