Summary
Polycyclic aromatic hydrocarbons (PAHs) are widespread pollutants with toxic and carcinogenic risks. This review details their sources, environmental contamination, human exposure, and regulatory guidelines.
Area of Science:
- Environmental Science
- Toxicology
- Public Health
Background:
- Polycyclic aromatic hydrocarbons (PAHs) are prevalent environmental pollutants.
- Many PAHs exhibit significant toxic and carcinogenic properties.
- Understanding PAH sources and exposure is crucial for risk assessment.
Purpose of the Study:
- To summarize available data on PAH properties and origins.
- To detail environmental contamination by PAHs in various media.
- To assess human exposure pathways and identify high-risk populations.
Main Methods:
- Comprehensive literature review of PAH properties, sources, and contamination.
- Analysis of environmental data for air, water, soil, sediments, and food.
- Evaluation of occupational and non-occupational exposure scenarios.
- Compilation of existing regulations and guidelines on PAHs.
Main Results:
- PAHs originate from both natural and anthropogenic sources.
- Widespread contamination of air, water, soil, sediments, and food by PAHs.
- Defined occupational and non-occupational exposure routes for humans.
- Identified populations with potentially elevated PAH exposure levels.
Conclusions:
- PAHs pose a significant environmental and health risk.
- Effective management requires understanding sources, exposure, and contamination.
- Regulatory frameworks are essential for mitigating PAH risks.
