海洋有机化学是近十余年才发展起来的一门交叉性学科.由于海洋开发利用的需要以及环境科学的兴起,促进了此学科的迅速发展. 一些生物标记化合物(如烷烃、脂肪酸和芳烃等),能为有机质的来源和沉积环境提供信息.此外,利用它们还可以识别环境是否受到污染.正构烷烃和饱合脂肪酸之所以被认为是典型的标记化合物,主要在于它们普遍存在于自然界中,并且能经受剧烈的降解作用(如高温和氧化反应等).多环芳烃则是现代沉积物中常见的微量成分,其中苝是陆源 Marine organic chemistry is an interdisciplinary discipline developed in more than ten years, which has promoted the rapid development of this discipline due to the needs of ocean development and utilization and the rise of environmental science. Some biomarker compounds (such as alkanes, fatty acids and aromatic hydrocarbons ), Which provides information about the source and sedimentary environment of the organic matter and, in addition, the use of them to identify whether the environment is contaminated.Normal paraffins and saturated fatty acids are thought to be typical marker compounds, mainly because they are ubiquitous in nature , And can withstand severe degradation (such as high temperature and oxidation reactions, etc.) Polycyclic aromatic hydrocarbons are common trace elements in modern sediments, of which perylene is a terrestrial source
