Paper Abstract

Petroleum refineries may emit large quantities of pollutants. Tomsk Petrochemical plant impact on the air quality. Most elements associated with the emitted aerosols that are sometimes under-reported or even not cataloged. Because snow is an efficient scavenger of the emitted aerosols, it offers for identifying contaminants. Herein, we present the element concentrations in the insoluble fraction of aerosols in snow samples collected between March 2009 and March 2013. We also develop strategies to identify the marker elements for snow cover contamination in the plant vicinity. In addition, the aerosols transfer was indicated at the distances. Samples were measured using instrumental neutron activation analysis and flameless atomic absorption method. Results show that As, Hg, Br, Sb and Zn were found to be the predominated elements alone with traces of other analyzed elements. Burning gas in flare’s plant could be proved to be a source for the toxic and mobile elements Hg, Sb and Br. It is identified that aerosols fallouts degrease away from the plant at a distance from 300 to 1500 m. This study revealed that element concentration did not significant changed between 2009 and 2013.
