Plasma-assisted destruction of polystyrene nanoplastics. [PDF]
NanoscalePlasma-assisted treatment with a falling-film plasma reactor can destroy polystyrene nanoplastics in aqueous solutions, yielding solutions with low particle counts, short-chain polystyrene oligomers, and decreased total carbon content.

Conjugated biopolymer assisted separation of nanoplastics from aqueous systems: a step towards sustainability [PDF]
RSC AdvancesNanoplastics pose a significant environmental concern as they enter aquatic systems through various anthropogenic pathways. Consequently, the removal of nanoplastics from water, particularly polystyrene, is of paramount importance.

Presence of nanoplastics in rural and remote surface waters
Environmental Research Letters, 2022 It is now established that microplastics are a pervasive presence in aquatic and terrestrial ecosystems. The same is assumed to be true for nanoplastics but data are lacking due to technical difficulties associated with sample analysis. Here, we measured

Lipidomic analysis of mussel hemocytes exposed to polystyrene nanoplastics
Environmental Research, 2022 Plastics production and usage has exponentially increased in the last decades around the world. Due to the insufficient waste management, a significant amount of plastic ends up in the environment, where they tend to fragment into micro- and nano-plastics (NPs), and accumulate in aquatic organisms with still unknown effects.

Evidence and Impacts of Nanoplastic Accumulation on Crop Grains
Advanced Science, 2022 Nanoplastics are emerging pollutants of global concern. Agricultural soil is becoming a primary sink for nanoplastics generated from plastic debris. The uptake and accumulation of nanoplastics by crops contaminate the food chain and pose unexpected risks

Polystyrene nanoplastics mediated the toxicity of silver nanoparticles in zebrafish embryos
Frontiers in Marine Science, 2023 The widespread distribution of nanoplastics and nanomaterials in aquatic environments is of great concern. Nanoplastics have been found to modulate the toxicity of other environmental pollutants in organisms, while few studies have focused on their ...

Synthesis of 14C-labelled polystyrene nanoplastics for environmental studies [PDF]
Communications Materials, 2020 AbstractAvailable analytical methods cannot detect nanoplastics at environmentally realistic concentrations in complex matrices such as biological tissues. Here, we describe a one-step polymerization method, allowing direct radiolabeling of a sulfonate end-capped nano-sized polystyrene (nPS; proposed as a model nanoplastic particle representing ...

Enhanced Formation of Dicarboxylic Acids in the Catalytic Oxidation of Polyethylene With O2 and NOx
Angewandte Chemie, EarlyView.The oxidation of polyethylene in the presence of a mixture of O2 and NOx and with Cu2+/V5+ as catalyst yields ∼51 mol% diacids, while retaining ∼80 mol% of the carbon in the oil fraction. The developed method is robust and tolerates several polymer types as well as impurities.
