Abstract:
European marine waters are infested with plastic, with an average density of 1 plastic item in every four square-meters. Research relevant to MPs-NPs ingestion by wild decapods in European waters is limited, none of which regards the European spiny lobster. Totally 4102 plastic particles were extracted from the spiny lobster stomach tissues of both sexes. Out of the 63 samples analysed only three (4.8%) of them were found with no plastic particles. The range of number of MPs in stomachs was from 20 to 273 MPs individual-1. The 98.3% were fragments. In total 3833 plastic particles were extracted from the gill tissues of both sexes. MPs were found in all samples (n = 50),99.2% of the detected particles were fragments. The MPs detected in gills ranged from 11 to 339 MPs individual-1. The DLS method was used in order to evaluate the NPs presence. Nanoplastics were detected in 22.6% of stomachs and in the 48.1% of gills. A total of 43 polymer types were identified in both tissues. Also, our study assessed the accumulation of heavy metals at the edible tail muscle. Certain elements were detected above the EU\'s Maximum Residue Level, including arsenic. The present results are alarming and the potential human health implications could be serious.
摘要:
欧洲海洋水域充斥着塑料,平均密度为每四平方米1个塑料制品。与欧洲水域野生足类动物摄入MPs-NPs相关的研究有限,都没有提到欧洲多刺龙虾。从两性的多刺龙虾胃组织中共提取了4102个塑料颗粒。在分析的63个样品中,只有三个(4.8%)没有发现塑料颗粒。胃中MPs的数量范围为20至273个MPs个体-1。98.3%是碎片。从两性的g组织中总共提取了3833个塑料颗粒。在所有样本中都发现了MP(n=50),99.2%的检测颗粒是碎片。在the中检测到的MPs范围为11至339个MPsindividual-1。使用DLS方法以评估NP的存在。在22.6%的胃和48.1%的g中检测到纳米塑料。在两种组织中总共鉴定了43种聚合物类型。此外,我们的研究评估了可食用尾部肌肉中重金属的积累。某些元素被检测到高于欧盟的最大残留水平,包括砷。目前的结果令人震惊,潜在的人类健康影响可能是严重的。
