International Humic Substances Society（IHSS）国际腐殖质协会，于1981年9月11日在美国科罗拉多州丹佛市成立，汇集了对腐殖质感兴趣的煤炭，土壤和水科学领域的科学家。IHSS拥有近900名科学家的成员。该学会被公认为促进科学教育和研究以及促进公众对腐殖质物质的理解的世界领导者。IHSS的座右铭是：“推进土壤和水中天然有机物的知识和研究”。该学会的目标包括建立和维护来自褐煤、淡水、矿泉土和有机土壤的腐殖酸和富里酸标准样品的集合，以及特征数据的汇编。此外，该学会还增加了参考样品，作为研究腐殖质材料的来源。IHSS每两年召开一次国际会议，汇集了来自土壤，煤炭，淡水和海洋科学的科学家。这些会议由顶尖科学家与IHSS董事会合作召集。

腐殖质Humic substances（HS）是在植物和微生物遗骸腐烂和转化过程中通过生化和化学反应在土壤，沉积物和天然水中形成的多分散材料的复杂和异质混合物（称为腐殖化的过程）。植物木质素及其转化产物、多糖、黑色素、角质、蛋白质、脂质、核酸、细炭颗粒等是参与这一过程的重要成分。腐殖质参与土壤和天然水中的许多过程：例如，土壤风化、植物营养、pH缓冲、痕量金属流动性和毒性、生物利用度、疏水性有机化学品的降解和运输、水处理过程中消毒副产物的形成以及黑水生态系统中的异养生产。因此，腐殖质受到各学科科学家的关注。

标准样品（Standard）和参考样品（Reference Samples）

International Humic Substances Society（IHSS）收集，分发和维护从矿物土壤，泥炭，伦纳石和河水中分离的冻干标准和参考样品。根据定义，IHSS标准和参考样品必须满足以下所有四个标准：

1. 标准样本必须来自IHSS为此目的专门指定的地点;

2. 标准或参考样品必须根据IHSS指定的特定程序制备;

3.（1）和（2）中涉及的标准样品制备必须在IHSS的直接监督下进行;

4. 样品必须被IHSS指定为标准或参考。

International Humic Substances Society(IHSS) was founded in Denver, Colorado, USA, on September 11, 1981 to bring together scientists in the coal, soil, and water sciences with interests in humic substances. IHSS has a membership of nearly 900 scientists. The Society is recognized as a world leader in fostering scientific education and research, and promoting public understanding of humic substances. The motto of the IHSS is: “To Advance the Knowledge and Research of Natural Organic Matter in Soil and Water”. The aims of the Society include the establishment and maintenance of a collection of standard samples of humic and fulvic acids from lignite, fresh water, a mineral soil, and an organic soil, and the assembling of characterization data. In addition, the Society has added reference samples that are a source of humic materials for research. The IHSS convenes biennial international conferences, which bring together scientists from the soil, coal, freshwater, and marine sciences. These conferences are convened by leading scientists in collaboration with the IHSS Board.

Standard and Reference Samples

IHSS collects, distributes, and maintains freeze dried standard and reference samples that were isolated from a mineral Soil, Peat, Leonardite, and River Water. By definition, IHSS standard and reference samples must satisfy all four of the following criteria:

1. A standard sample must have come from a site specifically designated by the IHSS for this purpose;

2. A standard or reference sample must have been prepared according to a specific procedure designated by the IHSS;

3. Standard sample preparations involved in (1) and (2) must have been conducted under the direct supervision of IHSS;

4. The sample must be designated as a standard or reference by the IHSS.
