摘要

采用在线监测方法于2009年7月8日至22日在广东省汕头、潮州、揭阳三市各选择1个有代表性的空气质量监测点同步进行PM

2.5

和 PM

监测。监测结果表明，粤东三市PM

2.5

和 PM

质量浓度低于部分沿海城市；PM

和 PM

2.5

的质量浓度日变化呈双峰分布，分别处在上午（6:00至10:00）以及下午（18:00至22:00）两个时间段；PM

和 PM

2.5

日平均浓度变化呈周期性波动，周期约为3～4 d；对于粤东三市区域，PM

2.5

/PM

为0.5215，说明PM

中细颗粒物含量大于粗颗粒物含量。

Abstract

2.5

and PM

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 PM

2.5

and PM

in the three cities of eastern Guangdong were lower than some coastal cities. PM

and PM

2.5

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 PM

and PM

2.5

fluctuated in a cycle of about 3 or 4 days. The portions of PM

2.5

were larger than those of other particles in sizes from 2.5 μm to 10 μm. The ratio of PM

2.5

to PM

was 0.521 5 in the three cities

in which measurements were carried out.
