Multilevel toxicity assessment of polypropylene microplastics and pyrene on mussels: DNA damage, oxidative stress, and physiological effects

The data are produced within the study to investigate the onsequences of microplastic pollution and pyrene on Mytilus galloprovincialis. We present an integrative assessment of polypropylene (PP) and pyrene, individually and in co-exposure, in mussel Mytilus galloprovincialis. Mussels were exposed to 1 mg L- 1 PP (~40 μm) and 50 μg L- 1 of pyrene for 7 and 14 days, representing a scenario relevant to highly polluted coastal areas. The study was published in Marine Pollution Bulletin 222 (2026) 118880.本数据集源自一项旨在探究微塑料污染与芘（pyrene）对地中海贻贝（Mytilus galloprovincialis）影响的研究。本研究对聚丙烯（polypropylene, PP）与芘分别及联合暴露下的地中海贻贝开展整合性评估。实验中将地中海贻贝暴露于1 mg·L⁻¹的PP（粒径约40 μm）与50 μg·L⁻¹的芘环境中，暴露时长分别为7天与14天，该实验场景契合重度污染沿海区域的实际情况。本研究发表于《Marine Pollution Bulletin》2026年第222卷，文章编号为118880。
