This study was conducted to investigate the concentration of heavy metals (pb and cd) in soil of fireclay mine of Abarkouh on essential oil percent and on thymol and carvacrol percent in Shirazi thyme (Zataria multiflora Bioss). Concentration of pb and cd elements of soil samples from two regions (around the mine and 800 meters distance from the mine as control) was measured and effect of these concentrations on essential oil percent and on thymol and carvacrol percent was determined. The concentration of pb and cd elements in soil of around the mine were 62.7 and 8.6 ppm, respectively and these concentrations were higher compared to control region. Mean comparison between essential oil percent of Shirazi thyme in two studied regions showed that essential oil percent of plants that grown in soil around the mine was reduced. There was no significant difference between thymol and carvacrol percent of Shirazi thyme in two studied regions
