海洋有机物质包含有类脂化合物、氨基酸蛋白质、多糖物和腐植物质等等。现代沉积物中尤其是海相三角洲中存在着与石油相似的烃类化合物。海洋中腐植物质的存在不仅涉及到海洋食物链和有机物地球化学循环,并且还在于腐植物质与金属元素形成络合物的能力。
Marine organic substances contain lipid compounds, amino acid proteins, polysaccharides and humic substances and so on. In modern sediments, especially in marine delta, there are petroleum-like hydrocarbon compounds. The presence of humus in the oceans involves not only the ocean food chain and the organo-chemical cycles, but also the ability of humic substances to form complexes with metal elements.
