Bivalves are the focus of experimental research as they can filtrate a broad size range of microplastics (MPs) with negative consequences for their physiology. Studies use a range of MP shapes, materials, sizes and concentrations raising the question on whether these reflect environmental observations. We review experimental studies on the effects of MPs on marine bivalves and contrast the MP characteristics used with corresponding data from the environment. Mussels were the most common bivalve across experiments which reflect their high abundance and broad distribution in the field. Although fibres are the dominant shape of MPs in coastal systems, most studies focus on spherules and beads, and MP concentrations are often orders of magnitude higher than environmental levels. For higher relevance of experimental findings we recommend that maximum experimental concentrations of MPs are in the range of 100-1000 particles/L, that there is more focus on microfibers and that concentration is reported in particles/volume.
双壳类动物是实验研究的重点，因为它们可以过滤广泛范围的微塑料（MPs），对其生理功能产生负面影响。研究使用了一系列 MP 形状、材料、大小和浓度，这引发了一个问题，即这些是否反映了环境观测结果。我们回顾了关于 MPs 对海洋双壳类动物影响的实验研究，并将使用的 MP 特性与环境中的相应数据进行了对比。在实验中，贻贝是最常见的双壳类动物，这反映了它们在野外的高丰度和广泛分布。尽管纤维是沿海系统中 MPs 的主要形状，但大多数研究集中在球体和珠子上，并且 MP 浓度通常比环境水平高出几个数量级。为了提高实验结果的相关性，我们建议 MPs 的最大实验浓度在 100-1000 个粒子/L 之间，更多地关注微纤维，并报告以粒子/体积表示的浓度。
