Nano/microplastics (N/MPs) induce phytotoxicity and represent a significant global threat to terrestrial agricultural ecosystems. However, the defense mechanisms of plants against different-sized N/MPs remain largely unknown. To address this knowledge gap, we investigated interactions between polystyrene (PS) NPs (50 100 nm) PS-MPs (200 500 with taro (Colocasia esculenta). We found that PS particles varying sizes exhibited differential root adsorption penetration, PS-NPs capable penetrating epidermis, whereas were totally excluded. Notably, demonstrated capacity recognize different responded degrees resistance. In reaction more toxic 50 nm PS-NPs, roots mobilized robust mechanism three levels: molecular, compositional, ultrastructural. This was achieved by activating lignin synthesis, carbohydrate metabolism, lipid transport, resulting in doubling lignified region increases cell wall thickness 116%, 56.3%, 22.5% exodermis, cortex, respectively. Consequently, excluded all four outside vascular tissue prevented contamination corms. Our study provides new insights into interaction demonstrates crucial role barriers sustaining food safety.

Abstract Microplastic (MP) pollution is widespread and has become a significant global environmental concern. This study represents the first attempt to investigate abundance of MPs in open dumping scrapyard sites Türkiye. Microplastics were identified soils surrounding these areas, spanning eight provinces. The samples analysed for MP distribution characteristics, including abundance, shape, size, colour type. extracted using density separation with saturated K 2 CO 3 , followed by treatment 30% H O . Chemical identification was conducted ATR‐FTIR μ‐FTIR. Various types detected soil samples, averages 311.6 ± 113.9 particles kg −1 areas 463.3 83.9 areas.

Abstract Microplastic (MP) pollution in terrestrial ecosystems is gaining attention, but there limited research on its effects leafy vegetables when combined with heavy metals. This study examines the impact of three MP types—polyethylene (PE), polyethylene terephthalate (PET), and polystyrene (PS)—at concentrations 0.02, 0.05, 0.1% w/w, along cadmium (Cd) biochar (B), germination, growth, nutrient absorption, metal uptake red amaranth ( Amaranthus tricolor L.). We found that different types did not negatively affect germination parameters like rate, relative vigor, speed. However, they increased phytotoxicity decreased stress tolerance compared to an untreated control (CK1). The presence MPs, particularly PS type, reduced phosphorus potassium while enhancing Cd uptake. For example, treatments 0.02 CdB, 0.05 0.1 CdB content A. seedlings by 158%, 126%, 44%, respectively, treatment (CK2). Additionally, contamination led plant height, leaf dry matter content, fresh weights, indicating adverse growth. Moreover, MPs bioconcentration factors translocation for Cd, suggesting might act as carriers absorption plants. On positive side, addition improved several root parameters, including length, volume, surface area, number tips potential benefits Our shows combination reduces growth increases risk food crops.
