Abstract

Abstract:

The paper analyzes air quality data of Hangzhou urban area from 2002 to 2006 , the results show that the Premier pollutant is PM10 in Hangzhou urban area. There are signifificant seasonal variations and " bimodal type " daily varietions of PM10 and PM2.5 . Ihe study of relationship between PM10 concentration and weather system indicate that the peak concentration pollution is easily appeared under the high_pressure control system, and PM10 concentration is relatively lower under the easterly system . The weather phenomenon as the haze and mist exist tremendous influence to PM2.5 and PM10 under a long-time stable weather condition.

Key words: inhalable particle materials(PM10 ) high_pressure control system　 easterlies system haze
