Distinct accumulation patterns, translocation efficiencies, and impacts of nano-fertilizer and nano-pesticide in wheat through foliar versus soil application.

The use of nano-chemicals in agriculture has been shown to enhance crop production through soil additions or foliar sprays. However, the accumulation pattern, translocation efficiency, mode of action of nanomaterials (NMs) via different application methods remain unclear. In this study, wheat was treated with CuO-NPs/CeO-NPs (50 and 100 nm) for 21 days using soil and foliar application separately.

Intergenerational neurotoxicity of polystyrene nanoplastics in offspring mice is mediated by dysfunctional microbe-gut-brain axis.

Nanoplastics (NPs) are ubiquitous in daily life, posing potential risks to the environment and human. While their negative effects on parental organisms have been extensively studied, intergenerational effects are still in the early stages of investigation. Here, we aimed to investigate the impact of maternal exposure to an environmentally relevant level of polystyrene NPs (PSNPs, 100 nm) during gestation and lactation (∼32 days, 50 μg/mouse/day) on neurotoxicity mediated by the microbe-gut-brain axis in offspring mice.
