Monthly sampling from August 2018 to December 2019 was carried out in the beach sediments of Calicut to understand the monthly accumulation and deposition pattern of microplastics (MP). The average abundance in terms of items per kg dry sediment during monsoon months was higher than that of non‐monsoon months. The sources and pathways of the sampled microplastics were identified using an existing forensic framework. The pathways of pellets and fibers were seen as drainage outlet and harbor, respectively. Exactly identified sources include polycarbonate urethane (PCU) fragments from foam, polypropylene (PP) and polyethylene (PE)+PP films from paints of boats, and PE and PE+PP from fishing nets. The MP concentration in recreational areas was consistently higher except during flood periods.

海洋微塑料的来源分配：迈向管理微塑料污染的第一步

从2018年8月至2019年12月在Calicut的海滩沉积物中进行每月采样，以了解微塑料（MP）的每月积累和沉积方式。在季风月份，每千克干沉积物的平均含量要高于非季风月份。使用现有的法医框架鉴定了采样的微塑料的来源和途径。颗粒和纤维的路径分别被视为排水口和港口。确切确定的来源包括泡沫塑料中的聚碳酸酯氨基甲酸酯（PCU）碎片，船用油漆中的聚丙烯（PP）和聚乙烯（PE）+ PP膜，以及渔网中的PE和PE + PP。除洪水期外，休闲区的MP浓度始终较高。
