Effects and Risk Assessment of Polycyclic Aromatic Hydrocarbons in the Soil Ecosystems
摘要
Polycyclic aromatic hydrocarbons (PAHs) represent as a long-lasting and stable environmental organic pollutant composed of hydrocarbons that threaten both ecology and individual well-being with long-term stability, mutagenic, carcinogenic, and teratogenic properties. Soil PAHs are dependent on industrial processes, transportation, automobile exhaust, and physico-chemical characteristics, including hydrophobicity and non-polar nature. Low solubility and strong sorption will lead PAHs to remain intact in soil and threaten both ecosystems and human health for a long time. PAHs ubiquitous occurrence in various environmental components (air, water, soil, biological organisms) and associated effects are future need using recent advanced detection techniques and improves the understanding of health risk assessment. The present chapter discusses the multiplicity of PAHs routes, associated risk assessment and reviews the recent practices to evaluate the PAH related risks and advance sustainable soil management practices and future perspectives.
