Title: Elemental composition and sources of inhalable particulate matter in the ambient air of Jiaozuo ctiy
Abstract: 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.
