Effects of clay minerals on the transport of polystyrene nanoplastic in groundwater

Water Research, 2022
Microplastics are widely detected in the soil-groundwater environment, which has attracted more and more attention. Clay mineral is an important component of the porous media contained in aquifers. The transport experiments of polystyrene nanoparticles (PSNPs) in quartz sand (QS) mixed with three kinds of clay minerals are conducted to investigate the ...

Sorption of polycyclic aromatic hydrocarbons to polystyrene nanoplastic

Environmental Toxicology and Chemistry, 2015
Abstract   Microplastic has become an emerging contaminant of global concern. Bulk plastic can degrade to form smaller particles down to the nanoscale (<100 nm), which are referred to as nanoplastics.

The potential toxicity of polystyrene nanoplastics to human trophoblasts in vitro

Environmental Pollution, 2022
Nanoplastics (NPs), the emerging contaminants in recent years, widely distributed in the environment and are bioaccumulated and biomagnified in organisms through food chain. A growing number of studies have detected plastic particulates in human placenta and blood. However, few studies have focused on their effects during human pregnancy. Herein, human

Exposure of polystyrene nanoplastics led to ferroptosis on cardiomyocytes

Environmental Pollution
Recent studies have revealed that nanoplastics (nm-sized nanoplastics may induce oxidative stress) can translocate into human cardiovascular tissues and potentially contribute to pathophysiological processes through mechanisms involving reactive oxygen species (ROS) generation.

Nanoplastics release from polystyrene foam containers

Journal of Hazardous Materials
Polystyrene (PS) foam is widely used in instant noodle containers, which exhibit a larger amount of nanoplastic (NP) release compared to other disposable plastic containers. The released NP particles can be absorbed into the body through ingestion and may adversely affecting the human body.
