Abstract

This study was conducted with the aim to determine concentration of benzene, toluene, ethyl benzene, xylene and gasoline in different water samples (drinking water, drain water and canal water) of dry port and surrounding residential area as Presence of excess these compounds in water pose many health problems like cancer, gastroenteritis, dysentery, diarrhea and viral hepatitis. Firstly, physical parameters (pH, turbidity, TSS and TDS) were analyzed as the analysis of these parameters is keen important to get an idea of any organic contamination in water and then in second step selective an sensitive approach of gas chromatography was used for the qualitative and quantitative determination of these compounds. Gasoline was detected in about all samples except one waste water sample. The detected concentrations of gasoline were 8503.2, 568.19, 11546.51, 345.29, 4042.82, 2835.67 and 182.96 ppm. Benzene was detected in all samples in concentrations of 1, 0.007, 391.11, 485.16,121.73,421.23, 183.88, 38.14, 138.12 and 306.87 ppm. Toluene was detected in all samples except one waste water sample and two canal water samples. Detected concentrations of Toluene were 20.45, 160.82, 64.47, 7.34 and 15.5 ppm. Moreover, xylene was not detected in any of the sample. BTEX and gasoline were detected in water samples in concentration exceeding the limits set by WHO and NEQS standards thus posing significant effects towards environment and health.
