Investigation on oil pollution of soils caused by gas condensate leakage in Asalouyeh

In this study, the concentration of total oil pollution (TPH) remaining in the sediments of Asaluyeh (Khozi city of Fars province), which was polluted in the fall of 2021 due to gas condensate leakage, was investigated. After the accident, aeration and mixing of soil from depth to surface and also due to rain, washing of pollution from surface to deep of soils occurred. Five months after performing these operations, the TPH level of the soil was checked. The results showed that the concentration of soil pollution in the study area (356.5 μg/g) was in the lower ranges of the moderate pollution level.
