Yatagan Thermal Power Plant consumes low-quality lignite produced from the Yatagan Basin, located in the western part of the Aegean region nearby Mugla City. The basin is aligned in a northwest-southeast direction. The dominant wind direction is also northwest-southeast, which controls the boundary of the waste at the disposal site. In this study, the concentration of 30 volatile elements was analyzed in coal, bottom ash, fly ash and background soil. The study area was divided into grids. The size of the grids was 1 km(2) for the background soil and 50-100 m for the ash in the vicinity of the waste disposal site. 15 fly and bottom ash, six coal and nine-background soil samples were analyzed according to a sequential technique using ICP-AES. The results reveal that heavy metal concentrations in the coal are below the world averages for coal whereas those of bottom ash and fly ash are within the world averages for the respective ashes, indicating heavy metal enrichment. It is recommended that extra care should be taken to prevent subsurface contamination in the study area.
