Abstract >Methane oxidation is a major environmental process in different types of soil. Due to its global warming potential, exact fluxes of methane from soil to the atmosphere are relevant for atmospheric and carbon flux modeling. In this context the investigation of the methane oxidation turnover rates is often carried out by measuring the isotopic fractionation during the involved biodegradation processes. Unfortunately, isotopic fractionation can be a result of both biodegradation and diffusion. Therefore, a thorough estimation of the diffusion‐related isotopic fractionation is mandatory for a correction of biotransformation relevant kinetic isotope effects. Here for the first time, we investigated the isotopic fractionation of methane by diffusion in a coarsely mixed crushed stone and soil material. Determined isotopic fractionations by diffusion in terms of enrichment factors were??0.0212?±?0.005 at 22.5?°C and??0.0218?±?0.003 at 30?°C. When estimating biotransformation of methane from stable isotope measurements, the fractionation by diffusion has to be subtracted for estimating correct biotransformation rates. The obtained data are relevant not only for the investigation of oxidation processes in landfills but can also be adapted to other coarse materials such as arctic and tundra as well as wetland and volcanic soils. As a consequence, including the isotopic fractionation by diffusion within calculations of biotransformation will allow determining more exact values under well‐known conditions for methane flux calculations. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >甲烷氧化是不同类型土壤中的主要环境过程。由于其全球变暖潜力，从土壤到大气中的甲烷的确切助焊剂与大气和碳通量建模相关。在本文中，通常通过测量所涉及的生物降解过程中的同位素分馏来进行甲烷氧化周转率的研究。不幸的是，同位素分级可以是生物降解和扩散的结果。因此，彻底估计与扩散相关的同位素分馏是强制性的，用于校正生物转化相关的动力学同位素效应。在这里，我们首次研究了通过在粗混碎的石材和土壤材料中的扩散来研究甲烷的同位素分馏。通过在富集因子方面通过扩散确定的同位素分馏？0.0212≤00.0.005，在22.5Ω℃，0.0218？±0.003，30.°C。当从稳定的同位素测量估算甲烷的生物转化时，必须减去通过扩散的分馏以估计正确的生物转化率。所获得的数据不仅与垃圾填埋场中的氧化过程调查相关，而且还可以适应其他粗材料，例如北极和苔原以及湿地和火山土壤。因此，包括在生物转化的计算中通过扩散的同位素分级将允许在甲烷通量计算的公知条件下确定更精确的值。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-23285/'>《Geochemistry, geophysics, geosystems》</a> <b style="margin: 0 2px;">|</b><span>2018年第9期</span><b style="margin: 0 2px;">|</b><span>共8页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Schulte M.&option=202" target="_blank" rel="nofollow">Schulte M.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Jochmann M.
