摘要：

Gaseous mercury is the major form of mercury in atmosphere. Accurate evaluation of amount of mercury and its trends in atmosphere needs effective collection and a sensitive and reliable tec determination technique. A method based on amalgamation and cold vapor atomic absorption spectrometry was developed for ultra-trace mercury determination and then used to analyse gaseous mercury in urban and rural atmospheres. The results indicated that the concentration of gaseous mercury in urban air is much gigher than that in rural areas. The concentrations of gaseous mercury under normal conditions and during inversion period were determined showing that mercury concentration during inversion period was much higher than that under normal conditions.
