Plastics may leach out harmful chemicals, such as plastic additives and monomers, to the environment. This study focused on three intrinsic plastic-derived contaminants, viz. bis(2-ethylhexyl) phthalate (DEHP), bisphenol A (BPA), and styrene, based on surface (0-5 cm) sediment samples taken from transition areas located in the human-impacted coastal zone of the southern Baltic Sea. The concentrations of DEHP in the sediments from the Gulf of Gdańsk and the Szczecin Lagoon ranged from 38 to 228 ng/g d.w. and from 494 to 807 ng/g d.w., respectively. The levels of sedimentary BPA varied from <1 to 32 ng/g d.w., whereas styrene was not detected in any of the samples studied. Compared to worldwide data, the levels of plastic-derived contaminants in the sediments from the Gulf of Gdańsk and the Szczecin Lagoon were generally not high. However, according to sediment quality guidelines, some adverse environmental effects are probable.
塑料可能会向环境中浸出有害化学物质，如塑料添加剂和单体。本研究基于从位于波罗的海南部人类影响沿海区过渡区采集的表层（0-5 厘米）沉积物样本，重点关注三种内在的源自塑料的污染物，即邻苯二甲酸二（2-乙基己基）酯（DEHP）、双酚 A（BPA）和苯乙烯。在格但斯克湾和什切青泻湖的沉积物中，DEHP 的浓度范围分别为 38 至 228ng/g 干重和 494 至 807ng/g 干重。沉积物中 BPA 的水平从<1 至 32ng/g 干重不等，而在所研究的样本中均未检测到苯乙烯。与全球数据相比，格但斯克湾和什切青泻湖沉积物中源自塑料的污染物水平通常不高。然而，根据沉积物质量指南，可能会产生一些不利的环境影响。
