Despite the increasing prevalence of atmospheric nanoplastics (NPs), there remains limited research on their phytotoxicity, foliar absorption, and translocation in plants. In this study, we aimed to fill knowledge gap by investigating physiological effects tomato leaves exposed differently charged NPs absorption NPs. We found that positively caused more pronounced effects, including growth inhibition, increased antioxidant enzyme activity, altered gene expression metabolite composition even significantly changed structure phyllosphere microbial community. Also, exhibited differential translocation, with penetrating into dispersing uniformly within mesophyll cells. Additionally, absorbed were able translocate roots. These findings provide important insights interactions between crop plants demonstrate NPs' accumulation crops could negatively impact agricultural production food safety.

Airborne microplastics (MPs) can undergo long range transport to remote regions. Yet there is a large knowledge gap regarding the occurrence and burden of MPs in marine boundary layer, which hampers comprehensive modelling their global atmospheric transport. In particular, efficiency with different sizes morphologies remains uncertain. Here we show hemispheric-scale analysis airborne along cruise path from mid-Northern Hemisphere Antarctica. We present inaugural measurements concentrations over Southern Ocean interior Antarctica find that fibers are transported more efficiently than fragments transect, dynamics generally similar those non-plastic particles. Morphology found be dominant factor influencing hemispheric Antarctic This study underlines importance long-range cycling environment.
