Speciated Atmospheric Mercury: Sources and Transport Across Southern Lake Michigan

In order to answer many of the most important questions regarding   mercury in the Great Lakes environment, such as how much mercury is   entering the Great Lakes and where this mercury originates,   additional monitoring is needed beyond that currently being   conducted by federally-run programs. In recent years, highly   sophisticated measurement techniques have become available, or are   being developed, that can provide answers to many of the pressing   questions surrounds where mercury deposition originates and what, if   anything, might be done to protect human health and the environment   from this pollutant. This study will use advanced techniques to   measure mercury in the air and rain at two sites along the coast of   southern Lake Michigan to provide the best estimate to date of how   much mercury is entering the lake from the atmosphere and what   sources are contributing to these mercury loadings.    There is often controversy surrounding estimates of how much mercury   is reaching local water bodies from long distances (such as   transport of mercury on a global scale) and how much is from nearby   sources. Recent research in the Ohio river valley showed that   approximately 7 % of the mercury measured at that location was from   nearly coal-fired power plants. Similar techniques will be used here   to identify the primary sources of mercury to southern Lake Michigan   and to determine which are local influences and which are from   further abroad.     (mercury); (toxic metals); (toxic metal); (Hg): (chemcials of   concern); (chemical of concern); (Lake Michigan)
