为考察桂林市大气汞的分布特征,采用金柱捕集-原子荧光方法对桂林市区大气汞浓度进行了采样测定,结果表明各采样点大气汞浓度：春季为3.42~5.50 ng/m3,夏季为7.80~11.18 ng/m3,夏季明显高于春季。同时以桂林电子科技大学花江校区采样站点为研究对象,研究了不同天气状况下大气汞的日变化规律,结果表明：不同天气状况下,大气汞浓度随时间的变化趋势相同,均为早上偏低,中午达到高峰,之后又呈现缓慢下降趋势。为了进一步研究大气汞浓度与天气的关系,从2013年4月18日至5月23日对桂林电子科技大学花江校区进行16次采样测定,发现晴天大气汞浓度最高,为10.14±2.1 ng/m3；雨天次之,为7.71±0.96 ng/m3；多云间阴天最低,为5.62±0.82 ng/m3。可见大气汞浓度受天气状况的影响。

Distribution characteristics of atmospheric mercury in Guilin was studied.The atmospheric mercury in Guilin was determined using gold trap and cold vapor atomic fluorescence spectrometry.The results showed that atmospheric mercury concentration was in the range of 3.42-5.50 ng/m3 in spring and 7.80-11.18 ng/m3 in summer.The concentration of mer-cury in summer was obvious higher than that in spring.The mercury concentration of atmospheric mercury in Huajiang campus was separately determined from morning to evening in the different weather conditions.The results showed that the diurnal variation was similar in different weather conditions,and was low in the morning and reached a peak at noon,and then slowly decreased in the evening.To study the relation between atmospheric mercury and weather,1 6 samples were de-termined from 18 April to 23 May 2013.The average concentration of atmospheric mercury in sunny,rainy and cloudy day respectively was 10.14±2.1 ng/m3 ,7.71±0.96 ng/m3 and 5.62±0.82 ng/m3 .The concentration of atmospheric mercury was affected by the weather conditions.
