Abstract

Several types of source-receptor modeling methods have been applied to the atmospheric mercury data collected by the long term monitoring site at PMRC, Underhill, VT to infer the possible emission source types and source areas that may have significant contributions to mercury deposition into the Lake Champlain Basin. The methods employed were potential source contribution function (PSCF) analysis, residence time analysis (RTA), and multiple regression analysis against the factors of the positive matri:x factorization (PMF) of the fme particulate data from the same site. The possible source areas are displayed by the PSCF maps and the RTA maps. Source contributions were calculated for vapor phase and particulate mercury.
