Geo-Environmental Assessment of Oil Contaminated Distribution in Coastal Sediments (Bushehr Province)

Study of available reports and maps indicates that Bushehr province is oil contaminated area because it is adjacent to Persian Gulf. Then assessment of pollution distribution in coastal line is the goal of this paper. Fourteen hypothetical transects used for site investigation of contaminated areas in this research which they are in tidal area and perpendicular to coast line. Their length is depending on regional tide and elevation of coasts. Sample analysis with High Performance Liquid Chromatography (HPLC) method shows slight oil contamination with Total Petroleum Hydrocarbons (TPH) in the study area. However, TPH quantity is less than 400 ppb for most soil samples. The results show that the pollution distribution isnt similar in different coastal sediment. Soil samples from deeper depth and nearer to coast line are more contaminated.
