挥发性有机硫化物（VOSCs）是自然界硫循环的重要组成部分。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）是大气中重要的挥发性有机硫化物（VOSCs）。其中，DMS占全球总VOSCs排放量的75％以上。DMS具有高反应活性，能够与大气中自由基发生氧化反应生成 SO2、甲基磺酸（MSA）等，对酸雨的形成有重要贡献；其次，这些产物可形成云凝结核（CCN）和硫酸盐气溶胶，对地球辐射平衡和气候变化有着重要的影响。MT的在大气中的反应活性更高，极易被大气中的自由基氧化生成SO2和硫酸盐（SO2-4）等，同样对大气环境有着重要的影响。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产生的重要来源之一。

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%.
