Anthropogenic Emissions of Reduced Sulfur Compounds from Municipal Landfill sanitary sites

The Gaseous sulfur compounds Which produce sulfate aerosols in the atmosphere扮演一个重要的角色在各种全球环境问题中。在特定的、碳基硫醚（COS）中，影响了链层臭氧的破坏和通过形成形成链层气溶胶的全球变暖。然而，它的贡献是不够的。Moreover，对COS和碳污染的人类起源发射的评估（CS2）是COS的前束剂不充分的;在本研究中，COS对还原了大气层气溶胶的形成，以及从公共陆地填充卫生站点中减少的硫化合物的产生的评估。主要的发现就像后面一样。1-D模型计算指标的结果，即COS对平流层气溶胶形成的贡献增加到了最近的平流层臭氧浓度降解的程度。The Landfill emissions of the Landfill emissions of reduced sulfur compounds indicate that the landfill which contain biodegradable components emission of reduced sulfur compounds indicate that the landfill which contain biodegradable components emits of reduced sulfur modegradfill，that the landfill which landfill含有生物降解的components emit remount of reduced sulfill remount of reduced sulfur fill remount of reduced sulfur fur fill rements，the landfill remount of the landfill rements，the landfill remount of reduced sulfill remount However，我们已经找到了一个从工业化国家向全球COS预算贡献的土地填充任务。

The gaseous sulfur compounds which produce sulfate aerosols in the atmosphere play an important role in various global environmental problems. In particular, carbonyl sulfide (COS) influences the stratospheric ozone destruction and the global warming through formation of the stratospheric aerosols. However, its contribution is not evaluated enough. Moreover, the evaluation of anthropogenic emissions of COS and carbon disulfide (CS2) which is the precursor of COS is insufficient.In this study, the contribution of COS to the formation of the stratospheric aerosols was reevaluated, and the emissions of reduced sulfur compounds from municipal landfill sanitary sites were measured. The main findings are as follows.・The results from 1-D model calculation indicate that the contribution of COS to the formation of the stratospheric aerosols has been increasing due to the recent decrease of the stratospheric ozone concentration.・The measurements of the landfill emissions of reduced sulfur compounds indicate that the landfill which contain biodegradable components emit large amount of reduced sulfur species. However, it was found that the landfill emission from industrialized nations contribute little to the global COS budget.
