Abstract
Release of untreated effluents from industries and domestic sources deteriorates the water quality of receiving water bodies and drains. Hence, characterization of wastewater holds an important place as it can help the use of this wastewater for other purposes. For this purpose, wastewater analysis of the selected parameters and quantitative validation was performed to determine the presence of persistent trace organic pollutants in samples collected from different sources of Lahore city of Pakistan. Total suspended solid for the respective samples was found to be exceeding the NEQS limits. Chemical oxygen demand for the wastewater samples was 896, 166, 419, 812 and 610 mg/L, respectively, all in excess of NEQS (150 mg/L). Similarly, the biological oxygen demand values were also above NEQS limits (80 mg/L). Trace organic pollutants selected for analysis included five pesticides/insecticides and three polycyclic aromatic hydrocarbons. The results showed the presence of 1,2-dichloropropane and 1,3-dichloropropane in all the wastewater samples, pesticides was identified in housing society sample and textile industry sample. Finis and bifenthrin were detected in housing society and Hudiara drain wastewater samples. In case of polycyclic aromatic hydrocarbons, phenanthrene was identified in textile industry sample. Anthracene was detected in samples of housing society, PET bottles industry and pharmaceutical industry.
