Study of physico-chemical properties, detection and toxicity study of organic compounds from effluent of MIDC Thane and GIDC Ankleshwar industrial zone

Abstract

Abstract The anthropological activities and huge industrialization to fulfil needs of mankind are making the remarkable and disastrous effect on aquatic life and responsible for severe pollution. The research deals with the identification and detection of organic pollutants present in industrial effluent by FTIR and GC–MS techniques. The samples were collected from paint, textile and dyes industries of MIDC Thane and GIDC Ankleshwar situated in western zone of India and recognized to be the most polluted cities in Asia. The samples were collected by standard operating procedure and then operated for extraction in ether so as to dissolve maximum organic compounds. These samples after extraction sealed in airtight glass vessel and used for FTIR and GC–MS analysis. The large number of organic compounds was detected by GC–MS analysis, whereas the presence of different functional groups of organic pollutants confirmed by FTIR analysis. The physico-chemical analysis was performed for effluent samples to know the different chemical factors associated with aqua samples. The statistical analysis of collected data was carried out; it comprises the mean, standard deviation, standard errors, Pearson correlation constants and regression analysis. The calculated results compared with WHO standards and water quality index were calculated. Large number of organic and aromatic compounds identified from GC–MS data and their toxicity is discussed.
