Microplastics (MPs), which are of increasing concern in almost all ecosystems, continue to be an environmental threat. In the present study, the presence of MPs is investigated by using the gastrointestinal tracts (GITs) obtained from the true frog individuals sampled in the past years. The sample consists of a total of 146 individuals obtained from various regions of Türkiye. The results show that MPs were found in 87 adult frog individuals. The most predominant shape of MPs found was fiber, with a predominance of transparent color, and ethylene-vinyl acetate (EVA) was also the most abundant microplastic material. The highest amount of MPs among adult frog populations were found in the Denizli province. The size of MPs ranged between a minimum of 66 and a maximum of 3770 μm. In addition, no relationship was found between the body length and weight of the frogs and the sizes of MPs. Historically, most MPs were found in samples from 1990 and the highest content in terms of both color and material was detected in 1990. MPs were detected in almost all the years studied, but microplastic abundance varied from year to year. These results can be explained by the number of samples, habitat, and feeding behavior of adult frogs.
微塑料（MPs）在几乎所有生态系统中引起了越来越多的关注，继续构成环境威胁。在本研究中，通过使用过去几年从真正青蛙个体中采集的胃肠道（GIT）来研究 MPs 的存在。该样本由来自土耳其不同地区的总共 146 个个体组成。结果表明，在 87 个成年青蛙个体中发现了 MPs。发现的 MPs 最主要的形状是纤维，以透明色为主，乙烯-醋酸乙烯酯（EVA）也是最丰富的微塑料材料。在成年青蛙种群中， MPs 含量最高的是代尼兹利省。 MPs 的大小范围从最小的 66 到最大的 3770 μm。此外，在青蛙的体长和体重与 MPs 的大小之间未发现任何关系。从历史上看，大多数 MPs 是在 1990 年的样本中发现的，在颜色和材料方面含量最高的是 1990 年。在几乎所有研究过的年份都检测到了 MPs，但微塑料的丰度每年都有所不同。这些结果可以用成年青蛙的样本数量、栖息地和摄食行为来解释。
