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.

这项赠款将支持作为国际腐殖质社会（IHSS）双年展的一部分举行研讨会的费用。研讨会的目的是讨论维持IHSS自然有机物（NOM）当前参考样本的未来需求，并考虑收集新参考名称样本的方法。 NOM的重要原因很重要。土壤中的名称也称为土壤腐殖质。 NOM也存在于海洋，所有湖泊和溪流中。 NOM不仅在全球碳循环中起着重要作用，而且NOM还与植物所需的营养反应，并控制许多有毒化学物质的命运。自1980年代中期以来，IHSS已向全球科学家提供了NOM的参考样本，以用于研究。这些参考名称样本的可用性使得比较了许多不同研究的结果。科学家参加研讨会将总结他们的建议，并准备一份报告，描述最新的理解NOM的进展。这笔拨款将支持作为国际腐殖质毒品协会（IHSS）双年展的一部分举行的研讨会的成本。研讨会的目的是讨论维持IHSS自然有机物（NOM）当前参考样本的未来需求，并考虑收集新参考名称样本的方法。自然有机物（NOM）代表了全球碳预算中的重要回顾者，并且参与了许多重要的生物地球化学和环境反应，从支持异养微生物活性到减弱痕量金属的运输以及持续的有机污染物。自1980年代初以来，研究NOM的科学界IHSS一直在努力发展对NOM化学的综合理解。此外，IHSS从陆地和水生环境中分发了标准和参考NOM，腐殖酸和富富酸，代表了从生物地球化学和全球视角的潜水员来源。参加研讨会的小组将在未来几年中制定建议，以维持当前参考和标准腐殖质物质的可用性。该小组还将准备一份综合论文，以审查了解NOM化学和反应性的最新进展，并通过使用IHSS的标准样本和参考样本来突出进度的方法。该研讨会将通过维持这些参考腐殖质物质的可用性来提高对NOM的理解，这些研究社区涵盖了环境工程和科学，土壤科学，化学，林长学和海洋学。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子和广泛影响的评估来通过评估来支持的珍贵的支​​持。
