The term "Plastisphere" refers to the biofilm layer naturally formed by microorganisms attaching to plastic surfaces. This layer possesses the capability to adsorb persistent organic and inorganic pollutants, particularly trace metals, which are the focus of this research study. Immersion experiments were concurrently conducted in five locations spanning four European countries (France, Ireland, Spain, and Italy) utilising eight distinct polymers. These immersions, repeated every three months over a one-year period, aimed to evaluate the baseline bioaccumulation of 12 trace metals. The study underscores the intricate nature of metal bioaccumulation, influenced by both micro-scale factors (such as polymer composition) and macro-scale factors (including geographical site and seasonal variations). Villefranche Bay in France exhibited the lowest metals bioaccumulation, whereas Naples in Italy emerged as the site where bioaccumulation was often the highest for the considered metals. Environmental risk assessment was also conducted in the study.

塑料圈中微量金属的生物累积：欧洲视角下的环境风险意识

术语“塑料球”是指由附着在塑料表面的微生物自然形成的生物膜层。该层具有吸附持久性有机和无机污染物的能力，特别是痕量金属，这是本研究的重点。使用八种不同的聚合物在四个欧洲国家（法国、爱尔兰、西班牙和意大利）的五个地点同时进行了沉浸实验。这些浸泡在一年内每三个月重复一次，旨在评估 12 种微量金属的基线生物累积情况。该研究强调了金属生物累积的复杂性，受到微观因素（例如聚合物成分）和宏观因素（包括地理位置和季节变化）的影响。法国自由城湾的金属生物累积量最低，而意大利那不勒斯的金属生物累积量通常最高。研究还进行了环境风险评估。
