摘要
通过调查发现在市工业区，粒子态汞浓度高，冬，夏平均值为０．９１和１．００ｎｇ／ｍ＾３，最高达１．９２ｎｇ／ｍ＾３，冬夏季无显著性差异，秋季浓度低，交通频繁区和交通商业混合区冬季平均值０．４５ｎｇ／ｍ＾３，夏季０．４９ｎｇ／ｍ＾３在清洁区大部分在０．１０ｎｇ／ｍ＾３左右，最低０．０７０ｎｇ／ｍ＾３，显示夏季和城区粒子态汞浓度偏高的特征。
The paper reports first the status of vapourized mercury of atmosphere partictes of Urban area in China. According to the monitoring results, we get following conclusions: ①The highest valus of mercury concentration is in industrial zone; ②The valus of mercuny concentration (1. 92ng/m￣3) in summer is higher than that in autumn; ③The vapourized mercury is fine particle in industrial zone, it is formed in the way that vapourized mercury adheres to ash which coming from the same pollution source. However, the mercury is coarse particle in clean region as the vapourized mercury adheres to soil particle and forms the particle mercury.
