Monitoring the presence of microplastics (MP) in marine organisms is currently of high importance. This paper presents the qualitative and quantitative MP contamination of two bivalves from the French Atlantic coasts: the blue mussel (Mytilus edulis) and the Pacific oyster (Crassostrea gigas). Three factors potentially influencing the contamination were investigated by collecting at different sampling sites and different seasons, organisms both wild and cultivated. Inter- and intra-species comparisons were also achieved. MP quantity in organisms was evaluated at 0.61±0.56 and 2.1±1.7MP per individual respectively for mussels and oysters. Eight different polymers were identified. Most of the MPs were fragments; about a half of MPs were grey colored and a half with a size ranging from 50 to 100μm for both studied species. Some inter-specific differences were found but no evidence for sampling site, season or mode of life effect was highlighted.
监测海洋生物中微塑料（MP）的存在目前非常重要。本文介绍了来自法国大西洋沿岸的两种双壳类动物——贻贝（Mytilus edulis）和太平洋牡蛎（Crassostrea gigas）中的微塑料定性和定量污染情况。通过在不同的采样点和不同的季节收集野生和养殖的生物，研究了三个可能影响污染的因素。还进行了种间和种内比较。贻贝和牡蛎体内的微塑料数量分别为 0.61±0.56 和 2.1±1.7 个/个体。鉴定出了八种不同的聚合物。大多数 MPs 为碎片；约一半的 MPs 为灰色，一半的 MPs 尺寸在 50 到 100μm 之间，这两种研究物种均如此。发现了一些种间差异，但没有证据表明采样地点、季节或生活方式有影响。
