中文摘要
众所周知,汞等污染物会在一些偏远的生态系统中积累,导致生物体中浓度较高,并对健康造成影响。然而,使生态系统对污染物积累或多或少敏感的因素以及这些因素如何随气候变化在很大程度上是未知的。该计划将量化控制生态系统中汞保留的反应,以及辐射、温度和湿度对这些过程的影响。因此,这项研究将提高我们预测哪些生态系统将对气候变化中的汞积累敏感的能力,并有助于确定食物网中汞含量升高的风险区域。
英文摘要
Contaminants such as mercury are known to accumulate in some remote ecosystems leading to high concentrations in organisms and resulting in health effects. However, the factors that make an ecosystem more or less sensitive to contaminant accumulation and how these factors change with climate are largely unknown. This program will quantify reactions that control mercury retention in ecosystems and the effects of radiation, temperature and moisture on these processes. As such, this research will increase our ability to predict which ecosystems will be sensitive to mercury accumulation with climate change, and help to identify areas at risk for elevated mercury in the food web.
