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）是对水生生态系统的主要威胁之一。令人惊讶的是，我们对它的发生及其对居住在小型水体中的生物的影响的了解仍然很少。这项研究的目的是调查池塘繁殖两栖动物t中MP的发生及其化学组成。总共从位于波兰西南部的8个池塘中收集了5种201种t。在所有检查地点和所有研究物种中均发现了MP。在测试的那些动物中，有53只（26％）的in摄入了71 MP。IR-ATR分析表明，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。
