溶解有机物(DOM)是地球表面天然水体中普遍存在的一种物质。溶解有机物质对全球碳平衡至关重要,对养分循环和气候变化具有影响/控制作用。碳显然是生命过程中的重要元素,而DOM代表了地球上碳的一个潜在的动态成分。除了DOM在影响生产力和气候方面的作用外,DOM的第二个作用是结合污染物并影响其生物利用度和传输。毒性预测模型,如生物配体模型(BLM),隐含地考虑了DOM对复杂金属的潜在影响,并减轻了它们的毒性。
英文摘要
Dissolved organic matter (DOM) is a ubiquitous substance in natural waters on the earth's surface. Dissolved organic matter is crucial in global carbon balance with implications/controls on nutrient cycling as well as climate change. Carbon is obviously a significant element in life processes and DOM represents a potentially dynamic component of carbon on earth. In addition to DOM's role in influencing productivity and climate, a secondary role of DOM is to bind pollutants and influence their bioavailablity and transport. Toxicity prediction models such as the Biotic Ligand Model (BLM) implicitly take DOM into account due to its potential to complex metals and mitigate their toxicity.
