英文摘要	[1] total gaseous mercury (tgm) concentrations in ambient air were monitored at an urban site in guiyang from 23 november 2001 to 30 november 2002 using a high temporal resolution 5 min mercury vapor analyzer (tekran 2537a). tgm concentrations follow lognormal frequency distribution pattern, and the mean tgm concentration at the measurement site is 8.40 ng m(-3) on the basis of 1 year observation. tgm concentrations in guiyang are significantly elevated compared to the continental global background values. coal combustion from both industrial and domestic uses is estimated to be the primary atmospheric source. a seasonal distribution pattern of tgm with a descending order of winter, spring, fall, and summer was observed. the highest tgm concentration in winter is attributed to household heating using coal. a consistent diurnal distribution pattern of tgm was obtained among all seasons, and the nighttime tgm concentration is elevated compared to the daytime values. meteorological conditions are responsible for the formation of diurnal tgm distribution pattern. tremendous efforts are needed to reduce mercury emissions from coal combustion to decrease tgm concentrations in guiyang.
