Heavy metals and microplastics have been considered as threats to the marine environment and the interactions between these two pollutants are poorly understood. This study investigates the interactions between metals adsorbed in pellets collected randomly from 19 beaches along the coast of São Paulo State in southeastern Brazil, comparing these levels with those in virgin pellets. The samples were analyzed for Al, Cr, Cu, Fe, Mn, Sn, Ti and Zn by inductively coupled plasma optical emission spectroscopy (ICP-OES). The polymers were solubilized via acid digestion. The highest levels occurred with Fe (227.78mgkg - Itaguaré) and Al (45.27mgkg - Guaraú) in the same areas, which are closer to the Port of Santos. The metal adsorption on pellets collected is greater than that on virgin pellets. In this context, pellets can be considered to be a carrier for the transport of metals in the environment, even in small quantities.
重金属和微塑料被认为是对海洋环境的威胁，而这两种污染物之间的相互作用还了解甚少。本研究调查了随机采集自巴西东南部圣保罗州沿海 19 个海滩的小球中吸附的金属之间的相互作用，并将这些水平与原始小球中的水平进行了比较。通过电感耦合等离子体发射光谱法（ICP-OES）对样品中的 Al、Cr、Cu、Fe、Mn、Sn、Ti 和 Zn 进行了分析。聚合物通过酸消解进行溶解。在距离桑托斯港较近的同一地区，Fe（227.78mgkg-Itaguaré）和 Al（45.27mgkg-Guaraú）的含量最高。小球上吸附的金属量大于原始小球上的金属量。在这种情况下，小球可以被认为是环境中金属运输的载体，即使数量很少。
