ClearDifferentially charged nanoplastics demonstrate distinct accumulation in Arabidopsis thaliana
Researchers exposed Arabidopsis thaliana plants to positively and negatively charged polystyrene nanoplastics and found that charge determined accumulation patterns, with positively charged particles penetrating deeper into root and leaf tissues than negatively charged ones.
Do differentially charged nanoplastics affect imidacloprid uptake, translocation, and metabolism in Chinese flowering cabbage?
Researchers found that positively charged nanoplastics inhibited plant growth and reduced imidacloprid translocation in Chinese flowering cabbage, while negatively charged nanoplastics accelerated pesticide accumulation in shoots, revealing charge-dependent interactions affecting food safety.
Indole-3-acetic acid and zinc synergistically mitigate positively charged nanoplastic-induced damage in rice
Positively charged 80 nm polystyrene nanoplastics had the greatest impact on rice seedling growth, reducing dry biomass by 41% and root length by 46%, while supplemental zinc and indole-3-acetic acid together significantly alleviated the nanoplastic-induced growth inhibition.
Comparative effects of polystyrene nanoplastics with different surface charge on seedling establishment of Chinese cabbage (Brassica rapa L.)
Researchers compared the effects of polystyrene nanoplastics with different surface charges on Chinese cabbage seedlings. The study found that positively charged amino-modified nanoplastics caused more severe phytotoxicity than negatively charged particles, significantly reducing photosynthetic pigment contents during plant growth stages.
Differential Responses of Spinach Cultivars to Micro-Nanoplastic Stress Under Hydroponic and Soil Cultivation Conditions
Researchers exposed two spinach cultivars to six concentration gradients of polyvinyl chloride micro-nanoplastics under hydroponic and soil cultivation conditions, finding that low to moderate concentrations had differing effects on germination characteristics, sprout morphology, and antioxidant capacity between cultivars.
Nano- and microplastics commonly cause adverse impacts on plants at environmentally relevant levels: A systematic review
Systematic review of 78 studies found that nano- and microplastics commonly cause adverse effects on plants even at environmentally relevant concentrations, with germination and root growth more strongly affected than shoot growth during early development. Chlorophyll levels were consistently reduced while stress indicators (ROS) and antioxidant enzymes were consistently upregulated across species.
Positively Charged Microplastics Induce Strong Lettuce Stress Responses from Physiological, Transcriptomic, and Metabolomic Perspectives
Researchers exposed lettuce leaves to microplastics carrying different electrical charges and found that positively charged particles caused significantly stronger stress responses than negatively charged or neutral ones. The positively charged microplastics accumulated more in leaf tissue and triggered widespread changes in gene expression and metabolic pathways. The study suggests that the surface charge of microplastics is an important factor in determining their toxicity to plants.
