Abstract:
An Andersen particle sampler (Model 20-709) has been used for the collecting and measuring of atmospheric total aerosol samples at Guangzhou,Liuzhou,Shaoguan,Nanning,Yangshuo and Longmen in South China during the winter and summer in 1988.The mass distributions of total aerosol and the distributions of fluorine,chlorine,nitric,sulphuric,sodium,ammonia,potassium,calcium,magnesium ions of water soluble have been analyzed.The results show that the coarse particles are obviously higher in industrial cities than those in clean regions.The sulphuric and calcium ions of water soluble of aerosols are obviously higher in industrial cities than those in clean regions, and chlorine ionsis markedly loss.
