  • Title: [The characteristics of metal elements in airbone particle in Taiyuan].
    Author: Yang J, Ma Y.
    Journal: Wei Sheng Yan Jiu; 1997 Mar; 26(2):87-9. PubMed ID: 10325608.
    Abstract:
    Airbone particle samples were collected using a five-stage classification air sampler. The contents of 16 metals in different diameter airbone particles were determined by atomic absorption spectrophotometry. Variations in the contents of metals were observed in different seasons and areas. The results showed that the contents of most metals were higher in winter than in summer. The contents of metals were higher in urban districts than in suburbs. The metals of being harmful to human body mainly concentrated in the < or = 2.0 microns particles. The enrichment factor of metals was calculated. The results showed that Pb, Cu, Zn, As, Se and Sb mainly originated from man-made pollution, while Al, Fe and Ca mainly originated from natural sources.
