PAHs are persistent organic pollutants spread worldwide in our environment, including air, soil, and water. They are a large class of organic pollutants released mainly from anthropogenic sources, including automobiles and incomplete combustion of fossil fuels, power plants, and natural sources like forest fires and volcanic eruptions. In recent years, a variety of treatment methods have been used to degrade PAHs in the environment. This paper reviewed the most frequent physicochemical methods for PAHs removal, including solvent extraction/soil washing, oxidation, ozone, solidification, and supercritical fluid extraction. The findings showed that combining physicochemical methods can be an effective option for better cleanup of PAH from contaminated areas.

Author Biography

Shahabaldin Rezania, Assistant Professor, Dept. of Environment & Energy, Sejong University, Korea

have PhD in Environmental Engineering. My main fields of research are wastewater treatment and fuel production from agriculture waste and green plants. I used aquatic plants for water purification as well as for bio-energy production. Wastewater treatment can be more effective using mixture of aquatic plants. I have also experience on using different lignocellulosic biomass specifically low lignin to enhance energy production in feasible way.
