The evaluation of nanoplastics bioaccumulation in living organisms is still considered an emerging challenge, especially as global plastic production continues to grow, posing a significant threat to humans, animals, and the environment. The goal of this work is to advance the development of standardized methods for reliable biomonitoring in the future. It is crucial to employ sensitive techniques that can detect and measure nanoplastics effectively, while ensuring minimal impact on the environment. To understand nanoplastics retention by freshwater organisms, phyto- and zooplankton, and mussels were exposed to gold-doped polymeric nanoparticles synthesized in our laboratory. The results demonstrated that measuring gold content using inductively coupled plasma mass spectrometry (ICP-MS), along with confirmation of its presence through electron microscopy in selected exposed samples provides insight into the accumulation and release of nanoplastics by organisms playing a relevant ecological role at the early levels of aquatic food webs.
评估纳米塑料在生物体中的生物累积性仍是一项新出现的挑战，尤其是在全球塑料产量持续增长，对人类、动物和环境构成重大威胁的情况下。这项工作的目标是推动未来可靠生物监测标准化方法的发展。采用能够有效检测和测量纳米塑料的灵敏技术至关重要，同时要确保对环境的影响最小。为了解淡水生物、浮游植物和浮游动物以及贻贝对纳米塑料的滞留情况，将它们暴露于我们实验室合成的金掺杂聚合物纳米颗粒中。结果表明，使用电感耦合等离子体质谱法（ICP-MS）测量金含量，并通过电子显微镜对选定暴露样本中纳米塑料的存在情况进行确认，能够深入了解在水生食物网早期发挥相关生态作用的生物对纳米塑料的累积和释放情况。
