9911756ChenThis award supports development of collaboration with Chinese researchers at the Chinese Academy of Sciences' Institute of Zoology to study the trophic transfer of contaminants to fish in Chinese lakes. The funds will be used to support a planning visit by the three PIs and one graduate student.Consumption of contaminated fish is a public health concern because fish are known conduits of exposure to contaminants such as PCB's and mercury by humans and wildlife. Fish accumulate contaminants over their lifetime, so their body burdens build up to levels significantly greater than those in the water. A mechanistic understanding of movement through the food chain in aquatic food webs is lacking for most contaminants but is urgently needed to predict the types of lakes and food webs that present the greatest risk to humans via fish consumption. Through this collaboration with China, there will be opportunities to combine interests and expertise to try to better understand the potential for human exposure to contaminants via the aquatic food chain.

9911756Chen该奖项支持与中国科学院动物研究所的中国研究人员开展合作，研究污染物向中国湖泊鱼类的营养转移。 这些资金将用于支持三名 PI 和一名研究生的计划访问。食用受污染的鱼类是一个公共健康问题，因为鱼类是人类和野生动物接触 PCB 和汞等污染物的已知途径。 鱼在其一生中会积累污染物，因此它们的身体负担会明显高于水中的水平。对于大多数污染物来说，缺乏对水生食物网中食物链运动的机械理解，但迫切需要预测通过鱼类消费对人类构成最大风险的湖泊和食物网类型。通过与中国的合作，将有机会将兴趣和专业知识结合起来，试图更好地了解人类通过水生食物链接触污染物的可能性。
