Microplastic (MP) contamination in marine organisms is a growing field of research internationally. However not much is known about MP presence in invertebrates in southern Africa. The aim of this study was to determine whether MPs occurs in mussels prevalent in Cape Town, South Africa. Mussels (Mytilus galloprovincialis, Choromytilus meridionalis and Aulacomya ater) were sampled at 27 sites in October 2018 and MPs were recorded in 98% of mussels analysed. Most MPs were filaments, dark in colour and the size ranged between 50 and 1000 µm. There were no significant differences in MPs between the mussel species, with an average of 2.33 (standard error ± 0.2) MP particles/g and 4.27 (standard error ± 0.5) particles/individual being recorded for all sites combined. This is the first record of MPs in mussels in the region and provides a baseline for further investigations and monitoring of MPs.
海洋生物中的微塑料（MP）污染是国际上一个日益增长的研究领域。然而，对于南非法罗里达州无脊椎动物中 MP 的存在情况知之甚少。本研究旨在确定在南非开普敦普遍存在的贻贝中是否存在 MPs。2018 年 10 月，在 27 个地点采集了贻贝（贻贝、南方贻贝和 Aulacomya ater），并在分析的 98%的贻贝中记录到 MPs。大多数 MPs 是丝状的，颜色较深，大小在 50 到 1000µm 之间。贻贝种类之间的 MPs 没有显著差异，所有地点的平均 MPs 颗粒数为 2.33（标准误差±0.2）/g，平均 MPs 个体数为 4.27（标准误差±0.5）/个。这是该地区贻贝中首次记录到 MPs，并为进一步调查和监测 MPs 提供了基线。
