微塑料是海洋环境中一个新出现的问题，因为它们的体积很小；它们可以被水生生物，特别是滤食性生物，如牡蛎摄取。海产品中微塑料的存在可能对食品安全构成威胁，迫切需要评估微塑料对人类健康的潜在风险。这项研究对中国海岸线上17个地点牡蛎中的微塑料进行了量化。定性属性，如形状和大小，也是在显微镜下确定的。此外，利用傅立叶变换红外光谱(MU-FT-IR)对聚合物的类型进行了鉴定。结果表明，牡蛎体内微塑料的平均丰度为0.62条/g(湿重)或2.93条/只。此外，抽样牡蛎中有84%的牡蛎吸入了微塑料，这表明中国沿海不同地区微塑料污染的高发。纤维是最常见的形状(60.67%)，最常见的尺寸是
Microplastics are an emerging concern in the marine environment due to their small size; they can be ingested by aquatic organisms, especially filter-feeding organisms, such as oysters. The presence of microplastics in seafood may pose a threat to food safety, and there is an urgent need to evaluate the potential risks of microplastics to human health. This study quantified the microplastics in oysters from 17 sites along the coastline of China. Qualitative attributes, such as shape and size, were also determined under a microscope. Additionally, the polymer types were identified using Fourier-Transform Infrared Micro-Spectroscopy (mu-FT-IR). The results showed that the average abundance of microplastics in oyster was 0.62 items/g (wet weight) or 2.93 items/individual. Additionally, 84% of the sampled oysters had inhaled microplastics, indicating the high prevalence of microplastic pollution in different coastal areas of China. Fibers were the most common shape (60.67%), and the most common size was
