Microplastic Accumulation in Hong Kong's Marine Sediment: Spatial Pattern and Potential Sources.

ABSTRACT: Marine microplastic (MP) contamination has become a global issue due to its ubiquity, persistence, and potential ecological risks. Marine sediment is recognized as the final sink for marine microplastics and has therefore received increasing scientific attention. Currently, limited research has focused on microplastic pollution in the marine sediments of Hong Kong, China. In this study, we conducted a comprehensive investigation across Hong Kong to assess the abundance, polymer composition, and morphological characteristics of microplastics in marine sediments. Spatial pattern, risk assessment, and potential source analysis were further performed based on the field data. Our findings reveal that microplastics were unevenly distributed in Hong Kong's marine sediment with abundance ranging f
