Abstract

Polycyclic aromatic hydrocarbons (PAHs) have carcinogenic, toxic and mutagenic traits. They are generated during incomplete
combustion of coal, oil, petrol, volcanic activities, and wood. The metabolism of PAHs transpires through oxidation or
hydroxylation of the cytochrome P450-mediated mixed-function oxidase system. Technologies such as air purifiers and air filters
are now available in the market, but it is strenuous for a common man to afford due to its higher cost. Heretofore, researchers
have not been able to find low-cost effective remediation techniques for airborne PAHs which requires sincere attentiveness. The
objective of this article is to propose a penny-wise and environmentally friendly remediation method for airborne PAHs. In this
review article, it is hypothetically suggested that the plants which can influentially play a significant remediating role against
benzene can also be effective in exterminating the polyaromatic hydrocarbons from the environment.
