Little is known about the effects of microplastics on terrestrial ecosystems, especially agricultural soils and terrestrial higher plants. Here, rice seedlings were exposed to two different-sized polystyrene (PS) microplastics (100 nm and 1 μm) at 0, 0.1, 1 and 10 mg L −1 under hydroponic conditions...
