2012年8月6日-19日，广东大气超级监测站对广东鹤山地区大气中过氧乙酰基硝酸酯（以下简称：PAN）进行了观测，并对影响其值变化的因素进行了分析。结果表明，PAN的最高值达到了4．654×10-9，存在一定程度的光化学污染现象。 PAN日变化呈典型单峰型，最高值通常出现在14：00-16：00，这与O3的日变化规律基本一致。此外，PAN值的变化与NO和NO2存在一定的相关性，PAN峰值均出现在NO与NO2比值较低的时段。

Atmospheric PAN was measured by online instrument at Guangdong Atmospheric Supersite of China , located in Heshan , in August 2012 .The variation pattern and its influence factors were analyzed .During this measurement , the highest concentration of PAN was 4 .654 ×10 -9 , indicating a moderate photochemical pol-lution in this area .The diurnal variation of PAN showed a typical unimodal pattern with a peak at 14:00-16:00 , which is similar to that of O 3 .Besides , PAN was also related to NO and NO 2 , with peaks appeared during time with low values of φ( NO)/φ( NO2 ) ratio.
