中文摘要:
      通过对在黄埔工业区收集的气溶胶样品的质量谱与水溶性离子成分谱的分析表明:总气溶胶质量与诸离子浓度均明显高于华南大陆的值,其分布表现为明显的3峰分布,气溶胶中以SO4-2,NO3-,Ca2+,NH4+为主要的离子成分;较之华南陆地测站,除离子浓度成倍增加外,SO4-2的浓度占了阴离子含量的绝大部分,NO3-,NH4+的含量比重显著增加,以及NO3-,SO4-2,NH4+,K+较多地存在于细粒态粒子中是其主要特点。
英文摘要:
      Being analysed of mass spectrum and water-soluableion composition spectrum of aerosol samples collected at Huangpu industrial aera, it is shown that the to talaerosol mass and ion density are obviously higher than those of inland station in South China, their distributions show at hree-peak pattern obviously, the mainion compositions in aerosol are SO4-2, NO3-, Ca2+, NH4+. Compared with the inland observation station in South China, besides the double increase of ions density, the density of SO4-2 accounts for the large part of the negativeions, the contents of NO3- and NH4+ increase greatly, and the main features are that NO3-, SO4-2, NH4+ and K+ exist mainly in mini-particles.
