This grant will support costs for a workshop to be held as part of the International Humic Substances Society (IHSS) biannual meeting. The goal of the workshop is to discuss future needs for maintaining the current reference samples of natural organic matter (NOM) of the IHSS and to consider approaches for collecting new reference NOM samples. NOM is important for several reasons. The NOM in soil is also known as soil humus. NOM is also present in oceans and in all lakes and streams. Not only does NOM play an important role in the global carbon cycle, but NOM also reacts with nutrients needed by plants and controls the fate of many toxic chemicals. Since the mid-1980’s, the IHSS has provided reference samples of NOM to scientists worldwide to use for research. The availability of these reference NOM samples has made it possible to compare results from many different studies. The scientists attending the workshop will summarize their recommendations and will prepare a report describing recent advances in understanding NOM.This grant will support costs for a workshop to be held as part of the International Humic Substances Society (IHSS) biannual meeting. The goal of the workshop is to discuss future needs for maintaining the current reference samples of natural organic matter (NOM) of the IHSS and to consider approaches for collecting new reference NOM samples. Natural organic matter (NOM) represents an important reservoir in the global carbon budget and participates in many important biogeochemical and environmental reactions ranging from supporting heterotrophic microbial activity to attenuating the transport of trace metal and persistent organic contaminants. Since the early 1980’s, the IHSS, the scientific community that studies NOM, has worked to develop an integrated understanding of NOM chemistry. In addition, the IHSS has distributed standard and reference NOM, humic and fulvic acids from terrestrial and aquatic environments, representing diverse sources from a biogeochemical and global perspective. The group attending the workshop will develop recommendations for sustaining the availability of current reference and standard humic substances for years to come. The group will also prepare a synthesis paper reviewing recent advances in understanding of NOM chemistry and reactivity and highlighting the ways in which the progress was advanced by using standard and reference samples from the IHSS. This workshop will advance understanding of NOM by maintaining the availability of these reference humic substances to the broad research community spanning environmental engineering and science, soil science, chemistry, limnology, and oceanography.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这笔赠款将用于支持作为国际腐殖物质学会（IHSS）半年一次会议的一部分举行的研讨会的费用。研讨会的目的是讨论今后是否需要维持国际水文科学协会现有的天然有机物参考样品，并考虑收集新的参考有机物样品的方法。NOM之所以重要，有几个原因。土壤中的NOM也被称为土壤腐殖质。NOM也存在于海洋和所有湖泊和溪流中。NOM不仅在全球碳循环中发挥重要作用，而且还与植物所需的营养物质发生反应，并控制许多有毒化学物质的命运。自20世纪80年代中期以来，IHSS向世界各地的科学家提供了NOM的参考样品，用于研究。这些参考NOM样品的可用性使得可以比较许多不同研究的结果。 参加研讨会的科学家将总结他们的建议，并将编写一份报告，描述在了解NOM的最新进展。这笔赠款将支持作为国际腐殖物质学会（IHSS）半年一次的会议的一部分举行的研讨会的费用。研讨会的目的是讨论今后是否需要维持国际水文科学协会现有的天然有机物参考样品，并考虑收集新的参考有机物样品的方法。天然有机物（NOM）是全球碳收支的重要储存库，参与许多重要的生态地球化学和环境反应，从支持异养微生物活动到减弱痕量金属和持久性有机污染物的迁移。自20世纪80年代初以来，研究NOM的科学界IHSS一直致力于发展对NOM化学的综合理解。此外，IHSS还分发了来自陆地和水生环境的标准和参考NOM、腐殖酸和富里酸，从地球化学和全球角度代表了不同的来源。参加讲习班的小组将提出建议，以便在今后几年维持现有的参考和标准腐殖物质的可用性。该小组还将编写一份综合文件，审查在了解NOM化学和反应性方面的最新进展，并强调通过使用IHSS的标准和参考样品推进进展的方式。该研讨会将通过维护这些参考腐殖物质的可用性来促进对NOM的理解，以广泛的研究社区，包括环境工程和科学，土壤科学，化学，湖沼学和海洋学。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。
