Plastic debris sized from 0.33 to 5 mm or so-called microplastic is an abundant environmental pollutant found worldwide in various ecosystems. The contamination has been threatening animals such as fish, wild birds, domesticated poultry, and waterfowls. This preliminary research aimed to reveal the evidence of microplastic contamination in domesticated duck to prove that plastic contamination has spread massively and depicts how far the local duck ingests microplastic. Total 25 duck samples were collected from local duck intensive husbandry in five cities, i.e., Semarang and Pati (coastal area), Salatiga (lowland area), and Temanggung and Magelang (highland area). Duck intestinal tract samples were collected and were further digested using 10 N KOH at 60–80 °C for 24 h. The mixture was then collected into vial tubes and was centrifuged to get the pellet. The microplastic identification was conducted using a stereo microscope based on its size and shape. Based on the observation result, microplastic debris in the form of the filament was 49, 39, and 27 per individual in the duck sample from Salatiga, Semarang, and Magelang, respectively. The ingestion of plastic may come from duck feed, such as rough fish (mainly were obtained from the Java Sea) and water. This finding is essential to disseminate since microplastic contamination can be transferred from animals to humans and threaten health. Also, this result can contribute to policymakers deciding on plastic reduction.

大小为0.33至5毫米的塑料碎片或所谓的微塑料是全世界各种生态系统中发现的一种丰富的环境污染物。污染威胁着鱼类，野鸟，家禽和水禽等动物。这项初步研究旨在揭示家养鸭子中微塑料污染的证据，以证明塑料污染已经大规模传播，并描述了当地鸭子摄入微塑料的程度。从五个城市的当地鸭子集约化饲养场收集了总共25个鸭子样品，这三个城市分别是三宝垄和帕蒂（沿海地区），萨拉蒂加（低地地区）以及Temanggung和Magelang（高地地区）。收集鸭肠道样品，并在60–80°C下使用10 N KOH进一步消化24小时。然后将混合物收集到小瓶管中并离心以得到沉淀。使用体视显微镜根据其大小和形状进行微塑性鉴定。根据观察结果，在来自萨拉蒂加，三宝垄和马格朗的鸭子样品中，细丝形式的微细塑料碎片分别为49、39和27。摄入塑料可能来自鸭饲料，例如粗鱼（主要来自爪哇海）和水。这一发现对于传播至关重要，因为微生物的污染可能会从动物转移到人类并威胁健康。同样，这一结果也有助于决策者决定减少塑料用量。在来自萨拉蒂加，三宝垄和马格朗的鸭子样品中，长丝形式的微塑性碎片分别为49、39和27。摄入塑料可能来自鸭饲料，例如粗鱼（主要来自爪哇海）和水。这一发现对于传播至关重要，因为微生物的污染可能会从动物转移到人类并威胁健康。同样，这一结果也有助于决策者决定减少塑料用量。在来自萨拉蒂加，三宝垄和马格朗的鸭子样品中，长丝形式的微塑性碎片分别为49、39和27。摄入塑料可能来自鸭饲料，例如粗鱼（主要来自爪哇海）和水。这一发现对于传播至关重要，因为微生物的污染可能会从动物转移到人类并威胁健康。同样，这一结果也有助于决策者决定减少塑料用量。这一发现对于传播至关重要，因为微生物的污染可能会从动物转移到人类并威胁健康。同样，这一结果也有助于决策者决定减少塑料用量。这一发现对于传播至关重要，因为微生物的污染可能会从动物转移到人类并威胁健康。同样，这一结果也有助于决策者决定减少塑料用量。
