POLYCYCLIC AROMATIC HYDROCARBONS (PAHS) INVENTORIES AND TREATMENT IN WATER TREATMENT PLANTS IN PERAK TENGAH

Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic compounds composed of two or more fused benzene rings and abundantly found in mixed use area. Therefore, the general field of interest in this thesis was PAHs contamination in Sungai Perak at Perak Tengah. The objectives of this research were (1) to determine PAHs inventories in Sungai Perak via genotoxicity evaluation of raw and treated water samples at water treatment plants in Perak Tengah and (2) to detect of PAHs using specific UV absorbances and gas chromatography mass spectrometry analyses and (3) to identify the optimum conditions for the degradation of PAHs contaminated water using UV/H2O2 (T1), photo-Fenton (T2) and combined photo-Fenton-like membrane catalyst reactor (T3) of both simulated solution and actual water samples. Allium cepa toxicity assay and detection of PAHs in water samples were conducted in the pollution inventories.
