Effect of advanced oxidation process for chemical structure changes of polyethylene microplastics

Aging of microplastics and nanoplastics induced by advanced oxidation processes in wastewater treatment and their biological toxicity

Environmental microplastics and their additives—a critical review on advanced oxidative techniques for their removal

AI summary · Read the abstract

Researchers reviewed how advanced oxidation processes — including photocatalysis and electro-Fenton methods — can break down common microplastics and their chemical additives like BPA in water, finding these techniques are more effective than traditional treatment methods but still require further study for large-scale use.

Removal of Environmental Microplastics by Advanced Oxidation Processes

AI summary · Read the abstract

This review examined the use of advanced oxidation processes (AOPs) to degrade and remove microplastics from surface waters, ocean waters, soils, drinking water, and wastewater. AOPs represent a promising technological pathway for eliminating microplastics at treatment facilities, which is critical given that conventional systems fail to fully prevent microplastic entry into drinking water and food sources.

A Review on the Fate of Microplastics: Their Degradation and Advanced Analytical Characterization

AI summary · Read the abstract

This review covers current methods for extracting, degrading, and analytically characterizing microplastics from environmental and biological samples, highlighting major gaps in photo-oxidation, biodegradation, and photo-thermal degradation approaches. Establishing effective microplastic degradation methodologies is essential for reducing their prolonged environmental persistence and preventing ongoing bioaccumulation of plastic fragments and associated toxic chemicals in food chains.

Degradation of Plastics and Formation of Primary and Secondary Microplastics

AI summary · Read the abstract

This review paper explains how everyday plastics like grocery bags, food containers, and water bottles break down into microplastics (tiny plastic pieces smaller than 5mm) through sunlight exposure, heat, weathering, and other natural processes. This matters because as plastic waste breaks down in the environment, it releases these microplastics, along with potentially toxic chemical byproducts, that can end up in our water, food, and air, raising concerns about long-term health effects that scientists are still working to fully understand.
