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.

A suture is a device, either natural or synthetic, which is used for ligation of blood vessels and in wound closure following surgery. Its major functions are to hold tissues together following wound closure or surgery. Neck dissection procedures leave open wounds which need to be approximated for the process of wound healing and aesthetic considerations. Henceforth the aim of the current study is to assess the type of sutures used in surgical wound closure of neck in patients with oral squamous cell carcinoma following radial neck dissection in private institutional setup in chennai. Data was procured from the case sheets of patients undergoing radial neck dissection following surgical management of oral squamous cell carcinoma. The data was tabulated in MS-Excel and analysed by SPSS software (Version 20). The results were inferred. 60% of the external surgical wound closure were sutured using silk sutures while 40% where sutured using polyglactin and nylon sutures. 60% of the internal wound closures were closed using polyglactin while 40% was using polypropylene and nylon.Polyglactin 910 and silk were the most predominantly used suture materials for internal and external surgical wound closure in an private institutional set up in Chennai.
