In 1985, the South Florida Atmospheric Mercury Monitoring Study was established to investigate several likely sources of Hg, as well as transport and deposition mechanisms. Field operations began on August 10, 1995, and ran continuously through September 6, 1995. Source Sampling was conducted at three facilities suspected of emitting Hg. The source sampling component investigated the chemical form and magnitude of Hg emissions from a resource recovery incinerator, a medical waste incinerator, and a coal-fired Portland cement kiln. In-stack measurements also included PM 2.5, elemental and organic carbon, trace elements, and trace gases. Field measurements were conducted at a network of five surface sites. Four surface sites were located in Dade County and one in Broward County. The mercury emitting sources (Davie, Miami Springs and Dade County), and one site located west of the urban sites adjacent to the Everglades (Thompson Park). Day and night air samples were collected for PM2.5, elemental and organic carbon, trace elements, and trace gases. Extensive meteorological data were collected. This report focuses largely on data completeness and the spatial-temporal variability of ambient concentration data.
