### Speciated measurements of atmospheric mercury plumes were o btained at an industrially

impacted residential area of East St. Louis, IL. These plumes were found to result in extremely high mercury concentrations at ground level that were com posed of a wide distribution of mercury species. Ground level concentrations as high as 235 ng m -3

### for elemental mercury (Hg 0 

### ) and 38 300 pg m -3

### for reactive mercury species (reactive gaseous (RGM) plus part iculate (PHg) mercury) were measured. The highest mercury concentra tions observed during the study were associated with plumes that contained high concentra tions of all mercury species (Hg 0 

### , RGM, and PHg) and originated from a source located sout hwest of the sampling site. Variations in proportions of Hg 0

### /RGM/PHg among plumes, with Hg 0

### dominating some plumes and RGM and/or PHg dominating others, were attributed to dif ferences in emissions from different sources. Correlations between mercury plumes and elevat ed NO x 

### were not observed; however, a correlation between elevated SO 2

### and mercury plumes was observed during some but not al l plume events. Despite the presence of six coal-fired powe r plants within 60 km of the study site, wind direction data along with Hg/SO 2 

### and Hg/NO x 

### ratios suggest that high-concentration mercury plumes impacting the St. Louis−Midwest Particle Matter Supersite are attributable to local point sources within 5 km of the site.
