Phthalates are widely employed plasticizers blended to plastic polymers that, during plastic aging and weathering are prone to leach in the surrounding environment. Thus, phthalates were proposed to indirectly evaluate MPs contamination in marine environments, with still uncertain and scarce data, particularly for wildlife. This study investigates simultaneously microplastics (MPs) and phthalates (PAEs) occurrence in wild Actinia equina and Anemonia viridis, two common and edible sea anemone species. Both species had a 100 % frequency of MPs occurrence, with similar average concentrations. PAEs were detected in 70 % of samples, with concentrations up to 150 ng/g in A. equina and 144.3 ng/g for A. viridis. MPs and PAEs present in sea anemone tissues appear to reflect seawater plastic contamination conditions in the study area. Given the rapid biodegradation of PAEs, occurrence and concentrations of both these additives and their metabolites could be useful tracers of short-term plastic debris-biota interactions.
邻苯二甲酸盐是广泛使用的增塑剂，用于与塑料聚合物混合，在塑料老化和风化过程中，这些增塑剂容易渗入周围环境。因此，有人提议用邻苯二甲酸盐间接评估海洋环境中的微塑料污染，但相关数据仍然不确定且稀少，尤其是关于野生动物的数据。本研究同时调查了野生马氏海葵和绿色海葵这两种常见可食用海葵物种中微塑料（MPs）和邻苯二甲酸酯（PAEs）的存在情况。两种物种中微塑料的出现频率均为100%，平均浓度相似。在70%的样本中检测到了邻苯二甲酸酯，马氏海葵中的浓度高达150纳克/克，绿色海葵中的浓度为144.3纳克/克。海葵组织中存在的微塑料和邻苯二甲酸酯似乎反映了研究区域海水中的塑料污染状况。鉴于邻苯二甲酸酯的快速生物降解，这些添加剂及其代谢物的存在和浓度可能是短期塑料碎片与生物群相互作用的有用追踪指标。
