中文摘要：

对焦作市城区与郊区空气可吸入颗粒物（PM10）质量浓度进行了研究,城区和郊区空气中PM10平均质量浓度分别为（331±68）μg/m3和（320±106）μg/m3,PM10质量浓度表现出一定空间和时间上的变化,城区空气中PM10质量浓度高于郊区,冬季PM10质量浓度高于其他季节.采用ICP-MS对PM10中的Fe,Zn,Pb,As,Mn,Cu,Cd,Se,Ni,Cr和Co质量浓度进行分析,也表现出一定空间和时间上的变化,元素组成以地壳元素为主（如Fe和Mn）.采用相关矩阵和富集因子法对PM10中元素来源进行了分析,结果表明,Fe,Mn,Ni,Co和Cr主要受自然因素控制,如土壤;As,Cd,Pb,Se,Cu和Zn主要受人为因素控制,如燃煤和交通尾气排放等.

英文摘要：

The particulate matters concentration of inhalable particulate matter（PM10） were determined at urban and suburban sites in Jiaozuo city.The average particulate matters concentration of PM10 were（331±68） μg/m3 at urban site and（320±106）μg/m3 at suburban site respectively.The PM10 showed some temporal and spatial variations,the particulate matters concentration of PM10 at urban site were higher than that at suburban site,whereas PM10in winter particulate matters concentrations were higher than in the other seasons at both sites.The elemental composition of PM10 were determined to measure the particulate matters concentration of Fe,Zn,Pb,As,Mn,Cu,Cd,Se,Ni,Cr and Co using inductively coupled plasma-mass spectrometry（ICP-MS）,which showed temporal and spatial variations.The elemental compositions were dominated by the terrestrial elements（i.e.,Fe and Mn）.In order to determine the sources of PM10,correlation matrixes and enrichment factor analysis were used,the results indicated that some elements including Fe,Mn,Ni,Co and Cr were mainly controlled by natural sources,such as soil,whereas other elements including As,Cd,Pb,Se,Cu,and Zn were mainly controlled by anthropogenic sources,such as coal combustion and traffic emission.
