Completion funding for data analysis and publication in the framework of DFG research unit 763, Natural halogenation processes in the environment - atmosphere and soil

该项目的目标是完成DFG研究部门763 -自然卤化过程（HALOPROC）-尚未完成的研究任务，并发表相应的科学成果。分布在所有环境分区（大气层、土壤圈和生物圈）中的卤代烃发挥着重要的生态作用，影响全球变暖、臭氧消耗和生态系统健康。它们可以提高生产力，但也是有毒物质。人们认为，半挥发性/挥发性有机卤素对生物圈造成的日益严重的污染对人类的福祉产生了重大影响。自然卤化过程最终会对（以前未改变的）生态系统的碳储存、运输和排放产生影响，导致额外的气候反馈和植物毒性效应。卤碳的形成及其在碳循环中的命运和作用尚不清楚。在过去的4年半HaloProc中，我们收集了大量的现场和实验室数据，这些数据包使我们能够更好地理解和描述陆地盐碱生态系统中的自然卤化过程现象，包括潜在机制的重要因素和驱动力。为了实现研究单元的目标，这些数据包必须是经过处理和评估以供出版。我们将提供证据证明陆地盐碱生态系统的重要性，迄今为止，人们对挥发性有机卤素的区域和全球预算知之甚少。根据HALOPROC中表达的假设和目标，将在拟议的四个月计划中编写并提交三份科学出版物。如果没有指定的博士后作为宣布的出版物的主要作者，哈洛方案的既定目标就难以实现。

The objective of this proposed completion funding is to finalize the pending research tasks of the DFG Research Unit 763 - Natural Hagenation Processes (HALOPROC) - and to publish the respective scientific outcomes.Halocarbons widespread in all environmental compartments (atmosphere, pedosphere, and biosphäre) play an important ecological role affecting global warming, ozone depletion, and ecosystem health. They can induce productivity but also act as toxicants. The increasing pollution of the biosphere through semi-/volatile organohalogens is considered to have a large impact on the well-being of mankind. Natural halogenation processes eventually make an impact on the carbon storage, transport and emission of (previously unaltered) ecosystems, resulting in additional climate feedbacks and phytotoxic effects. Halocarbonformation and their fate and role in the carbon cycle are not clear.In the past 4 ½ years of HaloProc we collected a large number of field and laboratory data, which enable us to better understand and describe the phenomenon of natural halogenation processes in terrestrial saline ecosystems including import factors and driving forces of the underlying mechanism.To achieve the objectives of the research unit these data packages have to be processed and evaluated for publication. We will provide evidence to the importance of terrestrial saline ecosystems up to now poorly understood regional and global budgets of volatile organohalogens.Based on the hypothesis und objectives expressed in the HALOPROC three scientific publications will be prepared and submitted in this proposed four month's program. Without the assigned PostDoc as leading author of the announced publications, the stipulated goals of HALOPROC are difficult to achieve.
