【摘要】 利用大气采样器采集上海市某工业区焦化厂,电厂和氯碱厂的大气颗粒物(PM10),结果显示,工业区中低环化合物占优势;焦化厂、电厂和氯碱厂含量最高的化合物分别是萘、苊和菲;煤炭燃烧是该工业区焦化厂和电厂多环芳烃的主要来源,氯碱厂多环芳烃可能主要是来自于其上风向的焦化厂,二者可能有弱的相关性;苯并(a)芘含量处于中等污染水平.更多还原

【Abstract】 The distribution characteristic, and sources of polycyclic aromatic hydrocarbons(PAHs)in an industrial zone of Shanghai. PM10samples were collected around the coking plant ,power plant and chlor-alkali chemical factory in the zone. The results indicated that 2-ring—3-ring compounds were predominant and the contents of naphthalene,acenaphthene,phenanthrene were the highest on particulate around coking plant ,power plant and chlor-alkali chemical factory. The predominant source of PAHs in coking plant and power plant were likely from the emission of coal combustion while the PAHs in chlor-alkali chemical factory may come from the windward coking plant. The BaP concentration and the potential health risk were in the medium level compared to them in other cities.更多还原
