Physico-chemical Assessment and Analysis of Hazardous OrganicSubstances from Textile Industrial Effluents from Sachin and Kadodara,GIDC, Surat, India.

Surat GIDC, Gujarat is one of the largest producers in textile industry in India. The ever growing demand is fulfilled by very fast supplying process, this leads to bad practices during textiles operations which causes water pollution in this region. Since Surat is closer to the Arabian Sea, the polluted water is passed in to the sea through various water channels therefore, it is necessary to identify and characterize hazardous substances from these effluents. For this study samples were collected from two important textile industry clusters viz. Sachin and Kadodara, GIDC, Surat and stored by following standard sampling procedures. Physico-chemical parameters such as pH, Chloride, Sulphate, Electrical Conductance, Total Dissolve Solid, COD and BOD were determined. Solvent extraction method was employed to prepare samples for the detection of organic substances by FTIR and GC/MS techniques. FTIR confirmed the presence of various functionalities related to organic origin and GC/MS technique revealed the presence of linear, cyclic and polycyclic aliphatic and aromatic organic compounds in the collected samples with high toxicity. Physico-chemical parameters were used for the statistical analysis of water samples and standard statistical methods such as mean, errors, standard deviation, regression coefficient analysis and correlation were used which were helpful for the determination of water quality index and the results obtain were compared to assign the water quality standards authenticated by WHO, USPH and BIS. The prime focus was to detect organic pollutants and the assessment proved the presence of hazardous organic substances in the collected textile effluent samples.
