【摘要】 对杭州市区大气中可吸入颗粒物(PM₁₀)中主要的元素、二次粒子及多环芳烃（PAHs）进行了采样分析,并对有机碳（OC）、元素碳（EC）进行了单独分析,明确了杭州市区大气中可吸入颗粒物(PM₁₀)的浓度分布状况,并用化学质量平衡法（CMB）进行了源分担率的计算,从而为有效地控制杭州市区的大气污染提供了科学依据。更多还原

【Abstract】 The elements and second--forming particles and PAH_s of PM₁₀ in Hangzhou urban atmosphere are de-termined,their quantity density,especially the elements of the organic carbon （OC） and elemental carbon （EC）,are obtained by use of sampling of particulate matter. Based on these data,the receptor model of chemical massbalance （CMB） is used to calculate the source apportionment of all air pollution sources. These researches arehelpful for pollution control in Hangzhou urban atmosphere.更多还原
