Abstract：
This study investigates the occurrence of anthropogenic fibres inside wild Paracentrotus lividus at a Mediterranean coastal area in 2020. From each sea urchin, the coelomic fluid was directly analysed while digestive tracts and gonads were removed, pre-treated with trypsin (0.3%) and digested with H2O2 (10%) before analysis. A total of 260 fibres and 1 fragment were found in 100 specimens, with an average of 2.6 items/individual. Fibres were more abundant in the digestive system, less in gonads and in the coelomic fluid, respectively. Fourier transform infrared (FTIR) analysis of representative fibres identified 67% natural (cotton-based) and 33% synthetic polymers (polyester) suggesting their origin from textiles, possibly released from laundry sewages. Overall, these results encourage further in-depth investigations on fibres accumulation and potential transfer through the trophic chain up to humans.
摘要：
这项研究调查了2020年地中海沿岸地区野生Paracentrotuslividus内部人为纤维的发生。从每个海胆，在去除消化道和性腺的同时直接分析体腔液，在分析前用胰蛋白酶(0.3%)预处理并用H2O2(10%)消化。共在100个标本中发现260根纤维和1个碎片,平均2.6个项目/个。消化系统中的纤维更丰富，性腺和体腔液较少，分别。对代表性纤维的傅立叶变换红外（FTIR）分析确定了67％的天然（棉基）和33％的合成聚合物（聚酯），表明它们来自纺织品。可能从洗衣店释放。总的来说,这些结果鼓励进一步深入研究纤维的积累和通过营养链向人类的潜在转移。
