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.

Effects of Brackish Water Irrigation on Salt Transport in Saline-Alkali Peat–Perlite Substrates and Lettuce (Lactuca sativa L.) Growth
Published on 2026-02-01 by Wendong Zhang, Caiyu Wang, Yiman Li, Qinghai He @MDPI
Abstract: Amid global freshwater scarcity and soil salinization, brackish irrigation is a potential alternative, yet its effects under low-leaching soilless systems remain unclear. We tested brackish irrigation (30 mmol L−1 NaCl; EC ≈ 4.8 dS m−1, including fertilizer) on lettuce (Lactuca sativa L.) grown in peat–perlite substrates with non-saline (CK), mildly saline (M), and moderately–severely saline (S) initial salinity. Substrate moi[...]
Our summary: Brackish irrigation affects salt transport in saline-alkali peat-perlite substrates. Lettuce growth is minimally impacted under non-saline and mildly saline conditions but significantly reduced in moderately-severely saline environments. The study highlights the need for tailored irrigation strategies based on initial salinity levels.
