粤东三市PM2.5和PM10质量浓度分布特征
The Distribution and Concentration of PM2.5 and PM10 in Three Cities of Eastern Guangdong
摘要
Abstract
PM2.5 and PM10 were monitored simultaneously by continuous on-line measurement instruments from July 8 to July 22, 2009 in Shantou, Chaozhou, Jieyang of Guangdong Province. The results showed that concentrations of PM2.5 and PM10 in the three cities of eastern Guangdong were lower than some coast al cities. PM10 and PM2.5 exhibited two peaks in a day, which were from 6 to 10 a. m. and from 18 to 22 p. m. , respectively. The daily averaged concentrations of PM10 and PM2.5 fluctuated in a cycle of about 3 or 4 days. The portions of PM2.5 were larger than those of other particles in sizes from 2. 5 (Am to 10 μm. The ratio of PM2.5 to PM10 was 0. 521 5 in the three cities, in which measurements were carried out.关键词
