CAREER: Understanding Chemistry, Transport and Fate of Mercury and Persistent Organic Pollutants through Global Atmospheric Modeling

这项研究将提高对有毒大气成分汞（Hg）和持久性有机污染物（POPs）的大气化学的理解和更好的量化。虽然汞和持久性有机污染物都构成重大的环境风险，但它们的大气行为，包括化学反应、源和汇以及气体-颗粒分配，还没有得到很好的了解。全球三维大气模型GEOS-Chem将与全球观测数据集分析结合使用，以深入了解这些污染物。该项目的教育和外联部分侧重于(1)培养研究生水平的科学家和工程师有效参与国际政治；(2)向全球谈判者，特别是那些参与全球汞条约谈判的谈判者通报大气汞研究的最新科学进展。为了实现这些教育目标，研究生将参与一系列以科学政策为重点的研究研讨会，开发一个以汞为重点的谈判模拟，并设计和实施一个由研究生在全球汞谈判期间进行的“会外活动”。

This research will improve understanding about and better quantify the atmospheric chemistry of the toxic atmospheric constituents mercury (Hg) and persistent organic pollutants (POPs). Though both Hg and POPs pose substantial environmental risks, their atmospheric behavior, including chemical reactions, sources and sinks, and gas-particle partitioning, is not well-understood. A global, three-dimensional atmospheric model, GEOS-Chem, will be used in combination with analysis of global observational datasets, to gain insights into these contaminants.The educational and outreach component of the project is focused on (1) training graduate-level scientists and engineers to participate effectively in international politics, and (2) informing global negotiators, specifically those engaged in negotiating a global mercury treaty, of the latest scientific developments in atmospheric mercury research. To accomplish these educational goals, graduate students will be involved in a research seminar series focused on science-policy, develop a negotiation simulation focused on mercury, and design and implement a "side event" to be conducted by graduate students during global mercury negotiations.
