Many of the previous direct flux measurements have focused on two distinct ecosystems, intertidal mudflats and Spartina altemiflora salt marshes. These coastal systems have the potential for large emissions of volatile reduced sulfur gases due to the availability of sulfate and organic matter. Intertidal mudflats (3.4) have a tendency towards anoxia, with concomitant production of H S via sulfate reduction. . altemiflora marshes (4T5) release DMS through the... 

The modification of silica gel with diethanolamine (DEA) resulted in a stable alkaline filter, capable to collect H2S, COS, CS2, S02, C02 and H20 from contaminated air.56 The presence of odorous mercaptanes and organic sulphides may be selectively determined, as these compounds do not react with the DEA and therefore are not collected on the filter. By means of this scrubber an automatic survey system has been developed allowing the detection and determination of the nature of odour nuisance, caused by industrial emissions of volatile organic sulphur compounds, up to the ppb-level. The system consists of two continuous, highly sensitive and fast responding sulphur analyzers. One of the detectors is equipped with an SO, scrubber and measures the total amount of non-S02 sulphur compounds. The other detects the organic S-compounds, using the amine-silica filter. 

Little work has been done to characterize air-surface exchange of chiral semivolatUe current-use pollutants. However, the observations of slightly enriched ( )-a-HBCDD and racemic fS- and y-HBCDD in Chinese urban air suggest that the atmospheric source of HBCDD may be a mixture of both local unweathered emissions and volatilization of weathered residues from soil [321]. Measurements of soil EF profiles for HBCDD have not yet been done to confirm or refute this hypothesis. 

It was shown, that the N-content in the fuel is a governing parameter determining the emissions of NO. Though rather simple assumptions were applied in this work, reasonable agreement to emissions measured for various fuels in different combustors was obtained. This confirms that devolatilization is dominating NO, emissions for high volatile biomass fuels.
