Effects of Polypropylene Microplastics and Copper Contamination on Rice Seedling Growth
Published on 2026-02-02 by Ziwen Hao, Steven Xu, Siquan Huang, Lin Wang @MDPI
Abstract: This study investigates the effects of polypropylene microplastics (PP-MPs) and copper (Cu), applied individually and in combination, on the growth (root and shoot length, fresh and dry biomass), peroxidase (POD) activity, and Cu accumulation of rice seedlings. A hydroponic experiment was conducted with four treatments: control (CK), PP, Cu, and PP+Cu. Exposure to PP-MPs slightly promoted seedling growth, whereas Cu markedly inhibited growth and induced chlorosis. Compared with Cu alone, co-expo[...]
Our summary: This study examines the effects of polypropylene microplastics and copper on rice seedling growth. Exposure to microplastics promoted growth slightly, while copper inhibited it and caused chlorosis. Co-exposure to both substances improved shoot growth and altered antioxidant responses, highlighting the complexity of their interactions.
