| 摘 要： | 使用新型便携式气悬颗粒物监测仪，测定了太原市某办公室内外微米级颗粒物携带的多环芳烃（PPAHs）可吸入颗粒物（PM10）的质量浓度。结果表明，室内和室外PM10浓度值都远远超过了国家Ⅱ级标准，分别是其2倍和3倍；而室外PPAHs污染水平分别相当于每人每天吸烟3支和4支。室内污染物浓度变化趋势与室外基本一致，室内外的PPAHs浓度日平均值之比为0．8,PM10浓度日平均值之比为0．5；吸烟等人为活动能引起室内污染物浓度的瞬时升高，吸烟时室内PPAHs浓度可达到同一时间室外浓度的3．4倍，PM10可达到2．7倍。

| Abstract: | Two types of new instruments were used to monitor the indoor and outdoor mass concentration of particle bound polycyclic aromatic hydrocarbons (PPAHs) and inhalable particulates (PM 10 ) in the air of a common office in Taiyuan. It was found that both indoor and outdoor concentration of PM10 exceeded the national standard II, and the indoor level of PPAHs equal to per capita smoking 3 pieces of cigarettes, while outdoor level equal to 4. Variation of indoor concentration was moderately correlated with variation in ambient concentration. Indoor to outdoor ratio of average concentration was 0.8 for PPAHs, and 0.5 for PM 10 . Smoking or other human activities would cause instant increase of indoor concentration, the highest indoor concentration could be 2.7 times (PM 10 ) or 3.4 times (PPAHs) higher than outdoor concentration of the moment. |
