Recent Advances in the Extraction of Polycyclic Aromatic Hydrocarbons from Environmental Samples
Polycyclic aromatic hydrocarbons (PAHs) comprise a group of chemical compounds consisting of two or more fused benzene rings. PAHs exhibit hydrophobicity and low water solubility, while some of their members are toxic substances resistant to degradation.
