The prevalence of microplastics along the coastal habitats has become a global concern owing to the increased input of plastic debris from multiple sources. The present study is the first of its kind to examine the prevalence and distribution of microplastics in Odisha coast. The average microplastic abundance in the nine stations along Odisha coastal beach is 258.7 ± 90.0 particles/kg of beach sediment. Among the stations sampled, Swargadwara was reported with the highest microplastic abundance of 378.3 ± 39.7 particles/kg of beach sediment andAbhayachandpurwas found with the lowest number of 153.3 ± 27.3 particles/kg. Different types of microplastics varying in color, size, and shape were encountered in the study. From the Raman spectroscopic analysis, twelve types of polymers including High Density Polyethylene, Polystyrene, Polyvinyl chloride, and acrylonitrile copolymer were identified.
由于来自多种来源的塑料碎片不断增加，沿沿海栖息地存在微塑料已成为全球关注的焦点。本研究首次调查了奥里萨邦海岸微塑料的存在和分布情况。在奥里萨邦沿海滩的九个站点中，平均微塑料丰度为 258.7 ± 90.0 个/千克海滩沉积物。在所采样的站点中，Swargadwara 报道的微塑料丰度最高，为 378.3 ± 39.7 个/千克海滩沉积物，而 Abhayachandpur 发现的微塑料丰度最低，为 153.3 ± 27.3 个/千克。在研究中遇到了不同颜色、大小和形状的微塑料。通过拉曼光谱分析，共鉴定出包括高密度聚乙烯、聚苯乙烯、聚氯乙烯和丙烯腈共聚物在内的十二种聚合物。
