Microplastic (MP) pollution is a ubiquitous and persistent pollution problem in the marine environment that is threatening marine life. In this study, the presence of MP in stuffed mussels sold in 5 Turkish cities was examined. The microplastic content of ready-to-eat stuffed mussels purchased from 41 different vendors in 5 different cities was studied using chemical digestion, density separation, and μ-Raman spectroscopy. The average amount of MP in the stuffed mussels was determined as 0.6 ± 0.1 (median = 0.6; IQR = 0.7) MP mussel−1. Among the 5 cities, the highest number of MP was found in Istanbul with 0.9 ± 0.1 MP mussel−1, while the lowest number was found in Bodrum with 0.3 ± 0.1 MP mussel−1. The MP were identified as fiber type 62.7% and fragment type 37.3%. According to the μ-Raman analysis, the largest amounts of identified polymer types were polyethylene 35% and polypropylene 15%. Stuffed mussels purchased from 92% of the vendors contained MP. If an average consumer eats 100 g of stuffed mussels/portion, it is estimated that there is a risk of consuming 5.8 MP/portion. MP pollution is a serious problem in seafood. This study showed that stuffed mussels could be one way in which humans are exposed to MP. Due to the possible increase of MP load in the over-processing of seafood products, the results suggested that the quantification of MP should also be included as a component of food security systems.

填充有微塑料:在土耳其市场出售的传统贻贝中存在微塑料

微塑料(MP)污染是海洋环境中普遍存在且持续存在的污染问题,正在威胁着海洋生物。在这项研究中,检查了在5个土耳其城市出售的贻贝酿制中的MP含量。使用化学消解,密度分离和μ拉曼光谱法研究了从5个不同城市的41个不同供应商处购买的即食贻贝的微塑料含量。馅贻贝中MP的平均含量确定为0.6±0.1(中位数= 0.6; IQR = 0.7)MP贻贝-1。在这5个城市中,伊斯坦布尔的MP数量最高,为0.9±0.1 MP贻贝-1,而博德鲁姆地区的MP数量最低,为0.3±0.1 MP贻贝-1。。MP被确定为纤维类型62.7%和碎片类型37.3%。根据μ-拉曼分析,确定的最大聚合物类型为聚乙烯35%和聚丙烯15%。从92%的供应商处购买的酿贻贝含有MP。如果每个普通消费者食用100克贻贝/部分的馅,估计有消耗5.8 MP /部分的风险。MP污染是海鲜中的一个严重问题。这项研究表明,贻贝酿造可能是人类接触MP的一种方式。由于海产品过度加工中MP含量可能增加,结果表明MP的定量也应作为食品安全体系的组成部分。
