Microplastics (MPs) in oceans adsorb different types of pollutants, which can negatively impact the food chain. The extensive use of personal care products (PCPs) has led to their ubiquitous environmental presence, and their partition between plastic matrices and surroundings is determined by their physico-chemical characteristics and environmental conditions. This work develops and applies a methodology to determine 12 UV filters (UVFs) and UV stabilisers (UVSs) in MPs collected in beach sand. The analyses were carried out by ultrasound-assisted extraction and ultrahigh-performance liquid chromatography with tandem mass spectrometry detection. The validated procedure was applied to MPs samples taken in sand samples from 13 beaches on the Canary Islands (Spain). The results showed the presence of 10 UV filters and UV stabilisers at concentrations between 1 and 4031 ng·g⁻¹, where octocrylene was the most frequently found. The target analytes were present in all the sampling beaches.

海洋中的微塑料（MPs）吸收不同类型的污染物，这可能会对食物链产生负面影响。个人护理产品（PCP）的广泛使用已导致它们在环境中无处不在，其在塑料基质和周围环境之间的划分取决于其理化特性和环境条件。这项工作开发并应用了一种方法来确定沙滩沙子中收集的MP中的12种紫外线过滤剂（UVF）和紫外线稳定剂（UVS）。通过超声辅助萃取和超高效液相色谱-串联质谱检测进行分析。经验证的程序应用于从加那利群岛（西班牙）的13个海滩的沙子样品中采集的MP样品。^-1，其中辛二烯是最常见的。目标分析物存在于所有采样海滩中。
