Synthetic microfibers are universally recognized as an emerging pollutant in all ecosystems. The present investigation focuses on the evaluation and quantification of synthetic microfiber released from domestic laundering wastewater from different regions of Bhubaneswar city of Odisha state of India. The estimated number of microfibers collected from 500 ml of sample varied from 200 to 500 in numbers with an average amount of biomass in the range of 0.4-4 g. The surface morphology of the samples was assessed by Scanning Electron Microscopic analysis which revealed that the fibers were having a length of approximately 10-30 mm and diameter of 10-20 μm. Carbonyl (CO) stretching band at 1711 cm and Aldehyde (CH) Weak bond at 2917.38 cm absorption were recorded from Fourier transform infrared spectroscopic analysis. As microfibers released from synthetic apparels are major source of environmental microplastic pollution their precise detection could help in controlling this problem.
合成微纤维被普遍认为是所有生态系统中的一种新兴污染物。本研究集中评估和量化了来自印度奥里萨邦布巴内斯瓦尔市不同地区家庭洗衣废水中释放的合成微纤维。从 500 毫升样品中收集的微纤维数量估计在 200 到 500 条之间,平均生物量在 0.4-4 克之间。通过扫描电子显微镜分析评估了样品的表面形态,结果表明纤维的长度约为 10-30 毫米,直径为 10-20 微米。傅里叶变换红外光谱分析记录了 1711 厘米处的羰基 (CO) 伸缩带和 2917.38 厘米处的醛 (CH) 弱键。由于合成服装中释放的微纤维是环境微塑料污染的主要来源,因此对其进行精确检测有助于控制这一问题。
