Microplastic (MP) pollution in the marine environment has gained much concern in recent years. This study investigated the occurrence of MPs in invertebrates collected on 18 mudflats and sandy beaches in Hong Kong and its relationships to biological taxon, feeding mode and habitat. In total 38 species of gastropods, bivalves and crabs were collected and the mean number of suspected microplastics ranged from 0 to 9.68 particles g wet weight or 0 to 18.4 particles individual. Around 26% of the suspected microplastics were confirmed to be synthetic polymers, including CP (cellophane), PET (polyethylene terephthalate), and PA (polyamide). Microplastic fibres were the most abundant type of MPs, followed by pellets. Significantly higher abundance of suspected microplastics was found in gastropods. Since MP abundance might vary with taxon, it is recommended to include different taxonomic groups in any ecological assessment of the impact of MPs.
近年来，海洋环境中的微塑料（MP）污染受到了广泛关注。本研究调查了香港 18 个泥滩和沙滩上采集的无脊椎动物中 MPs 的存在情况及其与生物分类群、摄食方式和栖息地的关系。共采集到 38 种腹足类、双壳类和蟹类，疑似微塑料的平均数量范围为 0 至 9.68 个颗粒湿重或 0 至 18.4 个个体。约 26%的疑似微塑料被确认为合成聚合物，包括 CP（玻璃纸）、PET（聚对苯二甲酸乙二醇酯）和 PA（聚酰胺）。微塑料纤维是最丰富的 MPs 类型，其次是颗粒。在腹足类动物中发现了更高丰度的疑似微塑料。由于 MP 丰度可能因分类群而异，因此建议在任何对 MPs 影响的生态评估中纳入不同的分类群。
