Abstract

In this study, the concentration of total petroleum hydrocarbon (TPH) remaining in the sediments of Asaluyeh (a city in Fars province) that were polluted in the fall of 2021 due to gas condensate leakage was investigated. After the accident, soil from deeper layers was mixed with surface soil and rain washed some of the pollution deeper into the soil. Five months after these operations, the TPH level of the soil was measured. The results showed that the concentration of soil pollution in the study area was 356.5 µg/g, which corresponds to the lower end of the moderate pollution range.

Highlights

  • The average TPH level in the soil samples, after lightening operation in during 5 months, was 356.5 µg/g.
  • The remaining pollution in the investigated area after 5 months of the accident was in the lower ranges of moderate to high pollution level,
  • The remaining pollution level in the analyzed soil samples were comparable with that in the sediments of the southern shores of the Persian Gulf, which are exposed to continuous natural and human petroleum compounds.
  • It is appropriate to use and compare different methods, including physical methods.
