SGER: Integrated Sampling Campaign Aimed at Understanding the Atmospheric Mercury Cycle on Cape Cod, Massachusetts

这项研究将集中在伍兹霍尔海洋研究所的流动汞实验室测量大气汞，该实验室隶属于美国地质调查局。伍兹霍尔的科学家将与美国地质勘探局的科学家合作，对元素汞、颗粒汞和活性气体汞进行测量。将在整个野外试验期间(共212天)收集辅助气溶胶样本。流动水星实验室将从2008年初到2008年8月在伍兹霍尔现场，因此需要快速反应才能利用它的存在。PI收集的辅助数据将有助于以最低成本进一步解释移动实验室进行的分析。这项研究的目标是更好地了解大气中汞的化学成分，特别是汞化合物的形态，这一点并不为人所知。汞是重大的环境和公共健康问题，因为众所周知，甲基化形式的汞在水生食物链中积累，并最终对人类产生毒性。

This research will focus on the measurement of atmospheric mercury at the Woods Hole Oceanographic Institution by the Mobile Mercury Laboratory, which is owned by the United States Geological Survey. Woods Hole scientists will be collaborating with USGS scientists in making measurements of elemental, particulate, and reactive gas mercury species. Ancillary aerosol samples will be collected for the entire field experiment period (a total of 212 days). The Mobile Mercury Laboratory will be onsite at Woods Hole from the beginning of 2008 until August 2008, and therefore a rapid response is required to take advantage of its presence. The ancillary data collected by the PI will be useful for further interpretation of analyses undertaken by the Mobile Lab at minimal cost.The goal of this research is to obtain a better understanding of the chemistry of atmospheric mercury, particularly the speciation of mercury compounds, which is not well known. Mercury is of significant environmental and public health concern due to well-known toxicity of methylated forms of mercury that accumulate in the aquatic food chain and, ultimately, humans.
