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

这项研究将侧重于由美国地质调查局拥有的移动的汞实验室在伍兹霍尔海洋研究所测量大气中的汞。 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、颗粒和活性气体汞物种进行测量。 将在整个田间试验期间（共212天）收集辅助气溶胶样品。 移动的汞实验室将于2008年初至2008年8月在伍兹霍尔现场，因此需要迅速作出反应，以利用其存在。 PI收集的辅助数据将有助于进一步解释移动的实验室以最低成本进行的分析。本研究的目标是更好地了解大气汞的化学性质，特别是汞化合物的形态，这是不为人所知的。 汞是一个重大的环境和公共卫生问题，因为众所周知的毒性甲基化形式的汞，积累在水生食物链，并最终对人类。

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.
