Polycyclic aromatic hydrocarbons (PAHs) are aromatic compounds with two or more fused benzene
rings in their structural configurations. PAHs do not contain heteroatoms and substituents on the ring system.
PAHs containing up to four rings are called light PAHs while those that contain more than four rings are considered
as heavy PAHs. Heavy PAHs are more stable and......  hiện toàn bộ
