Abstract: This study delved deeply into the effects of PS - 100 and NH₂ - PS - 100 on NCM460 cells, filling a void in the research regarding the impacts of these two specific microplastics on this type of cell within the realm of microplastic cytotoxicity. It laid the groundwork for the subsequent establishment of a more comprehensive theoretical framework of microplastic cytotoxicity. This study aimed to explore the effects of 100 - nanometer polystyrene microplastics (PS - 100) and 100 - nanometer amino - functionalized polystyrene microplastics (NH₂ - PS - 100) on normal human colorectal mucosal cells (NCM460 cells). NCM460 cells were treated with different concentrations of PS - 100, NH₂ - PS - 100, and their mixtures, and the cell viability was detected using the Cell Counting Kit - 8 (CCK - 8) assay. The results showed that the co - exposure of PS - 100 and NH₂ - PS - 100 could significantly reduce the viability of NCM460 cells in a concentration - and time - dependent manner. This finding provides a theoretical basis for understanding the potential health risks of microplastic.
