CHROMATOGRAPHY MASS-SPECTROMETRIC ANALYSIS OF 4 POLLUTED RIVER WATERSFOR PHENOLIC AND ORGANIC-COMPOUNDS

Forty-four water samples from eleven sampling points were collected fr om four highly polluted rivers of northern India once in each four sea sons during 1988-1989. The samples were analyzed for phenol, chlorophe nols, a few bromophenols and other organics. Phenol was found to be ab sent in all the analyzed samples. Trichlorophenol and pentachloropheno l were frequently detected. Comparatively, the Ganges river was most p olluted at Kannauj followed by Narora, Kachala and Fatehgarh. Maximum phenols were found at Mathura downstream of the Yamuna river followed by Mathura upstream, Okhla, ITO and none at Wazirabad. No phenols were detected in the water of the rivers Hindon and Kali at Ghaziabad and Aligarh, respectively. Some other organic pollutants were also identif ied by their mass spectra and supported by data from the computerized library, but, not quantified.
