Microplastics (MPs) are one of the major threats to aquatic ecosystems. Surprisingly, our knowledge of its occurrence and its impact on the organisms that dwell in small water bodies is still scarce. The aim of this study was to investigate the occurrence and chemical composition of MPs in tadpoles of pond-breeding amphibians. In total, 201 tadpoles belonging to 5 species were collected from 8 ponds located in southwestern Poland. MPs were found in all examined sites and in all studied species. Among those tested, 53 (26%) tadpoles ingested a total of 71 MPs. IR-ATR analysis revealed that particles were of anthropogenic origin and included nylon, polyurethane, polyisoprene and 1,2 polybutadiene.
微塑料（MPs）是水生生态系统的主要威胁之一。令人惊讶的是，我们对其在小型水体中的存在及其对栖息生物的影响的了解仍然有限。本研究旨在调查池塘繁殖两栖动物的蝌蚪中 MPs 的存在和化学组成。总共从位于波兰西南部的 8 个池塘中收集了 201 只属于 5 个物种的蝌蚪。在所有检查的地点和所有研究的物种中都发现了 MPs。在测试的样本中，有 53 只（26%）蝌蚪总共摄入了 71 个 MPs。衰减全反射傅里叶变换红外光谱（IR-ATR）分析表明，这些颗粒是人为来源的，包括尼龙、聚氨酯、聚异戊二烯和 1,2-聚丁二烯。
