%X To investigate the emission of dimethylsulfide in near-shore waters seriously disturbed by human activities in China, using the solid absorption-desorption and cryogenic preconcentration method, sampling and analysis of seawater and atmospheric DMS in Qingdao near-shore waters were carried out during 2001-2002. The results showed that the spatial distribution and seasonal variation of seawater DMS concentrations and sea-air fluxes were evident. In summer, the average of seawater DMS concentrations was highest, amounting to 1169.47 ng x L(-1) and lowest in spring, only 226.99 ng x L(-1). The obvious concentration gradient in estuarine, landscape and Olympic Game areas were observed in summer, but in spring and autumn is not so evident. Sea-air flux of DMS was mainly determined by seawater concentration, therefore the sea-air flux coincided with seawater concentration. Average atmospheric DMS concentration was higher in the summer (256.44 ng x m(-3)) and lower in the autumn (195.64 ng x m(-3)). The diurnal variation of atmospheric DMS was discussed in paper.
