Characteristics and Sources of Atmosphere Aerosols in Chengdu Industrial Park

摘要

摘要: 用等离子体原子吸收发射光谱(ICP-AES)、X-射线衍射(XRD)、傅立叶变换红外光谱(FT-IR)及扫描电子显微镜/X射线能谱(SEM/EDX)等分析方法,对采自成都工业区的大气气溶胶样品的矿物组成、化学元素组成及气溶胶表面特征和粒度大小进行了研究.结果表明,成都工业区大气气溶胶以细粒为主,Ca,Cu,Zn,As,Pb,Cd和Hg等有毒有害元素含量较高,主要含有石膏、α-石英、长石、高岭石等矿物及非晶质SiO2,气溶胶物质主要来源于燃煤燃油烟尘、冶金工业粉尘及地面扬尘.

Abstract: The phase components,contents of major elements and microelements,surface character-istic and size of atmospheric aerosols in the Chengdu industrial park were investigated by using inductively coupled plasma atom emission spectroscopy (ICP-AES),X-ray diffraction(XRD),Fourier transfer infrared spectroscopy(FT-IR),scanning electron microscope(SEM) and X-ray energy-dispersion spectroscopy(EDX).The research result shows that atmospheric aerosols in the Chengdu industrial park are mainly fine and contain a high content of poisonous and harmful chemical elements,such as Ca,Cu,Zn,As,Pb,Cd and Hg,and main phase components are gypsum,α-quartz,feldspar,kaolinite and non-crystalloid SiO2.The particulate materials in the industrial park originate mainly from soot of burning coal and oil,metallurgical dusts,and road and soil dusts.
