Al-Arbaeen and Al-Shabab are two highly polluted lagoons lying along the Jeddah Coast. Surface sediments were collected from both lagoons to assess the levels and spatial distribution of polycyclic aromatic hydrocarbons (PAHs), as well as study the effect of environmental conditions on PAH concentrations. The concentration ranges for Σ38-PAHs in Al-Arbaeen and Al-Shabab lagoons were 5.4-5,372 ng/g...
