Objective:Polycyclic aromatic hydrocarbons are teratogenic and mutagenic, for their determination 50 water samples were taken from Hattar industrial area, TIP housing society, Hazara University DhodialMansehra and Kahuta industrial triangle Islamabad. Methods: Samples were analyzed with the help of High Pressure Liquid Chromatography for the determination of 5 Nitro PAHs including: Nitronaphthalene (NN), Nitrofluorine (NF), 9Nitroanthracene (NA), 3-Nitrofluoroanthene (NFA), Nitropyrene (NP). Results: Maximum amount 1ng/L of 1-NN was detected in the water samples of Industrial Estate, Hattar.The samples taken from Hattar industrial Estate phase 1, 3-nitro PAHs were detected in different concentration, 9-NA = 0.4ng/L, 2-NF = 0.637ng/L in 1 st sample and 0.34ng/L in 2 nd sample, 1-NP 0.66ng/L, 0.21ng/L and 0.5ng/L in 3 different samples.The samples taken from Hattar industrial Estate phase 1V, 4-nitro PAHs were detected 1-NN = 1ng/L, 0.69ng/L, 2-NF = 0.9ng/L, 9-NA = 0.87ng/L and 1-NP = 0.4ng/L. The sample taken form Kahuta Industrial Triangle, 4 nitro PHAs were detected 1-NN = 0.42ng/L, 2-NF = 0.87ng/L, 0.63ng/L, 9-NA = 0.78ng/L and 3-NFA = 0.1ng/L.The sample taken from Industrial Estate I-9 Islamabad, only one nitro PAH 9NA = 0.41ng/L was detected. The samples taken from TIP Housing Society, Industrial Zone Rawat Islamabad, Abbottabad, Qalanderabad, DhodialMansehraand commercial bottle of any beverages no nitro PAHs were detected.Bottled drinking water was also checked and no appreciable concentrations of nitro polycyclic aromatic hydrocarbons were detected in these samples. Conclusion: It is concluded that commercial water supplies are safe for health. The underground water near industrial areas particularly Hattar industrial area is not good for human use. While Rawat Industrial Zone is well planned for water supply and drainage so there no nitro PAHs were detected.
