Simulation and Characterization of Nanoplastic Dissolution under Different Food Consumption Scenarios

Toxics, 2023
Understanding of the potential leaching of plastic particles, particularly nanoplastics (NPs), from food packaging is crucial in assessing the safety of the packaging materials. Therefore, the objective of this study was to investigate potential exposure

Sulfonate-Modified Polystyrene Nanoparticle at Precited Environmental Concentrations Induces Transgenerational Toxicity Associated with Increase in Germline Notch Signal of Caenorhabditis elegans

Toxics, 2023
Recently, the transgenerational toxicity of nanoplastics has received increasing attention. Caenorhabditis elegans is a useful model to assess the transgenerational toxicity of different pollutants. In nematodes, the possibility of early-life exposure to

Combined effects of nanoplastics and heavy metal on antioxidant parameters of juvenile tri-spine horseshoe crabs

Frontiers in Marine Science, 2022
Juvenile tri-spine horseshoe crabs (Tachypleus tridentatus) were exposed to determine the effects of single and combined stresses of polystyrene nanoplastics (nano-PS) and heavy metal (Cu2+) on antioxidant enzyme parameters. The juveniles were exposed to

Predator traits influence uptake and trophic transfer of nanoplastics in aquatic systems–a mechanistic study

Microplastics and Nanoplastics
Predicting the response of aquatic species to environmental contaminants is challenging, in part because of the diverse biological traits within communities that influence their uptake and transfer of contaminants.

Particle properties and environmental factors control atmospheric transport and deposition of micro- and nanoplastics

Communications Earth & Environment
Atmospheric deposition plays an important role in the global distribution and long-range transport potential of micro- and nanoplastic particles. However, our mechanistic understanding of contributing processes remains limited.
