Polycyclic aromatic hydrocarbons (PAHs) are dangerous microscopic contaminants which are organic in nature and characterized by the presence of two or more phenyl rings, which are notably resistant to degradation. PAHs originate from man-made as well as natural sources including volcanic eruptions forest fires, petroleum, coal, and oil-based products such as gasoline, as well as improper disposal of industrial and domestic waste, crude oil extraction, and spills. They are potentially a threat to human health, plants, animals, and the environment as a whole. Environmental scientists are exploring numerous methods for treating PAH-contaminated water and soil, which encompass biological, chemical, physical, and thermal technologies. The conventional approach to PAH decontamination typically involves the use of harsh chemicals and a process that consumes significant energy, leading to a push for more sustainable and eco-friendly alternatives. This chapter reviews recent progress in green technologies for PAH decontamination, including bioremediation, electrokinetic remediation, phytoremediation, adsorption (utilizing adsorbents like zeolites, biomass derivatives, geosorbents, silica, and graphene-based materials), advanced oxidation processes, enhanced remediation through biocatalysts, and nanotechnology.
