The surge in plastic production has spurred a global crisis as plastic pollution intensifies, with microplastics and nanoplastics emerging as notable environmental threats. Due to their miniature size, these particles are ubiquitous across ecosystems and pose severe hazards as they are ingested and bioaccumulate within organisms. Although global plastic production has reached an alarming 400.

Ecological effects of micro/nanoplastics on plant-associated food webs.

Micro/nanoplastics (MNPs) contamination is a potential threat to global biodiversity and ecosystem functions, with unclear ecological impacts on aboveground (AG) and belowground (BG) food webs in terrestrial ecosystems. Here, we discuss the uptake, ingestion, bioaccumulation, and ecotoxicological effects of MNPs in plants and associated AG-BG biota at various trophic levels. We propose key pathways for MNPs transfer between the AG-BG food webs and elaborate their impact on terrestrial ecosystem multifunctionality.

Article Synopsis
  • The rise of plastic pollution is a serious global issue that poses both environmental and health risks, particularly due to microplastics (MPs) and nanoplastics (NPs) released from degrading plastics.
  • Humans are regularly exposed to these tiny particles through ingestion, inhalation, and skin contact, leading to potential health impacts, especially in vital systems like cardiovascular, nervous, reproductive, and digestive systems.
  • This review compiles the latest research on the toxic effects of micro- and nanoplastics in human health, aiming to increase awareness and support the development of strategies to combat this ongoing plastic crisis.

Foliar implications of polystyrene nanoplastics on leafy vegetables and its ecological consequences.

Article Synopsis
  • - The study investigates the impact of airborne micro-nanoplastics (MNPs) pollution on leafy vegetables, focusing on how Polystyrene Nanoplastics (PS-NPs) affect four species: Brassica rapa var. chinensis, B. rapa var. parachinensis, Amaranthus viridis, and Allium tuberosum.
  • - Results indicate that PS-NPs accumulate in the epidermal layers of the leaves, particularly around stomatal openings, with higher levels on both sides of the leaves compared to cross-sections, and accumulation varies based on leaf structure.
  • - The presence of PS-NPs leads to decreased chlorophyll content and photosynthetic efficiency, ultimately impacting the growth and nutritional quality of these
