Polycyclic aromatic hydrocarbons (PAHs) an organic molecules with several fused aromatic rings that are known to have carcinogenic and environmental polluting qualities. The study focuses on soil toxicity, origins, routes of human exposure, and potential remediation methods of polycyclic aromatic hydrocarbons. There are several drawbacks to polycyclic aromatic hydrocarbons (PAHs), especially in soil conditions. These highly persistent organic compounds, which frequently arise from incomplete combustion of organic materials, tend to accumulate in soil over time. Because PAHs are known to be harmful and carcinogenic, this accumulation raises concerns for human health in addition to endangering biodiversity and soil quality. Furthermore, because of their propensity to contaminate groundwater, they pose a threat to aquatic ecosystems and may expose communities to additional harm. Through their detrimental effects on microbial communities, which are essential to the cycling of nutrients and the general health of the soil, PAHs can also upset important soil processes. Additionally, the adherence of PAHs to soil particles makes cleanup difficult and expensive. This hampers remediation efforts. All things considered, the fact that PAHs are found in soil emphasizes how critical it is to address their sources and put into place practical measures to lessen their negative effects on the soil, environment, and human health.
