| Abstract: | Based on the analysis of the compositon and the element content of dust fall in Xi'an urban area and in constrast with the element content of the Malan loess depositted 18 000 yeas ago,and at that time there was no modernizing industry,the element characteristics and variations of the dust fall are studied. Meantime,the degree of pollution and pollution source of the air as well as source of dust fall are also investigated. |
