ABSTRACT This study is based on different IR spectra of nylon 6 and nylon 6.6 who are most common plastic in environment comes from domestic and industrial waste. Study is focused on amid II band (C=O stretch ) Amid I band (NH bending) NH stretch. Water filter for sampling and collection of debris from Harike wetland was done with help of plankton net in winter season. By using standard digestion and density separation methods suspected miscroplastic collected and analyzed by FTIR. IR spectra of both virgin and sample were matched and found that nylon 6 is present in Harike wetland. The source of Nylon may be lateral invasion or from different water bodies who are integral part of Harike wetland.
