Large-sized polystyrene microplastics induce oxidative stress in AML12 cells.

Microplastics (MPs), particularly those exceeding 20 μm in diameter, are increasingly detected in environment and animal tissues, yet their cytotoxicity remains poorly understood. While existing studies focused on MPs with relatively small sizes (≤ 20 μm) or nanoplastics (NPs), the biological impacts of large-sized MPs and amino-modified MPs are underexplored. In this study, we investigated the oxidative stress (OS)-mediated responses of alpha mouse liver 12 (AML12) cells to 50 μm polystyrene MPs (PS-MPs) and polystyrene-amine modified MPs (PS-NH-MPs) at concentrations of 0, 0.

Microplastics in the Amur tiger's habitat: Occurrence, characteristics, and risk assessment.

Microplastics (MPs) are emerging environmental pollutants that pose a significant threat to wildlife within forest ecosystems. However, the quantity and types of MPs in wildlife forest habitats remain unclear. This study is the first to assess the distribution of MPs in the Amur tiger habitat of northeast China.
