揮發(fā)性有機(jī)硫化物（VOSCs）是自然界硫循環(huán)的重要組成部分。二甲基硫醚（DMS）、甲硫醇（MT）、羰基硫（COS）、二硫化碳（CS2）和二甲二硫（DMDS）是大氣中重要的揮發(fā)性有機(jī)硫化物（VOSCs）。其中，DMS占全球總VOSCs排放量的75％以上。DMS具有高反應(yīng)活性，能夠與大氣中自由基發(fā)生氧化反應(yīng)生成 SO2、甲基磺酸（MSA）等，對(duì)酸雨的形成有重要貢獻(xiàn)；其次，這些產(chǎn)物可形成云凝結(jié)核（CCN）和硫酸鹽氣溶膠，對(duì)地球輻射平衡和氣候變化有著重要的影響。MT的在大氣中的反應(yīng)活性更高，極易被大氣中的自由基氧化生成SO2和硫酸鹽（SO2-4）等，同樣對(duì)大氣環(huán)境有著重要的影響。微生物降解含硫氨基酸（尤其是甲硫氨酸）是自然界中 DMS和 MT產(chǎn)生的重要來(lái)源之一。

Volatile organic sulfides (VOSCs) are an important part of the natural sulfur cycle. Dimethyl sulfide (DMS), methyl mercaptan (MT), carbonyl sulfide (COS), carbon disulfide (CS2), and dimethyl disulfide (DMDS) are important volatile organic sulfides (VOSCs) in the atmosphere. Among them, DMS accounts for more than 75% of the total global VOSCs emissions. DMS has high reactivity and can react with free radicals in the atmosphere to form SO2, methanesulfonic acid (MSA), etc., which has an important contribution to the formation of acid rain; secondly, these products can form cloud condensation nuclei (CCN) and sulfates Aerosols have an important impact on the Earth's radiation balance and climate change. The reactivity of MT in the atmosphere is higher, and it is easily oxidized by free radicals in the atmosphere to generate SO2 and sulfate (SO2-4), etc., which also has an important impact on the atmospheric environment. Microbial degradation of sulfur-containing amino acids (especially methionine) is one of the important sources of DMS and MT production in nature.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed a special sulfide chromatographic column using the Summa tank air pre-concentration system and gas chromatography-mass spectrometry for the determination of volatile and malodorous sulfides in ambient air. The output limit is low, and the monitoring results can meet the daily monitoring and analysis. When the injection volume was 400 mL, the detection limit of the method was 0.5~0.9 μg/m~3, the mean value of the corresponding factor was less than 20%, the method precision was 2.1%~10.3%, and the recovery was 96.1%~112%.
