Interactions and transport of hexavalent chromium with microplastics in detergent-dissolved water

Copper complexation and chromium reduction by dissolved organic matter derived from microplastics

Sorption of Potentially Toxic Elements to Microplastics

AI summary · Read the abstract

Researchers reviewed how microplastics can adsorb toxic heavy metals from their surrounding environment, effectively acting as vehicles that concentrate and transport harmful elements. This sorption behavior increases the potential risk microplastics pose to organisms that ingest them, including humans.

Sorption of Potentially Toxic Elements to Microplastics

AI summary · Read the abstract

Microplastics readily sorb potentially toxic elements including heavy metals and metalloids from surrounding water, acting as concentrated carriers of these hazardous substances through aquatic food webs. This sorption capacity amplifies the toxicological risk of microplastic ingestion for organisms, including humans who consume contaminated seafood.

Cr(III) - Cr(VI): variability of the speciation of chromium released into the environment by microplastic weathering

AI summary · Read the abstract

Researchers examined how the weathering of microplastics releases chromium into the environment, with particular attention to the speciation shift between the less toxic Cr(III) and the highly toxic, carcinogenic Cr(VI) forms.

Interaction Between Microplastics and Pollutants

AI summary · Read the abstract

Researchers examined how microplastics interact with environmental pollutants, finding that their accumulation causes physical harm including suffocation and energy depletion in aquatic organisms, while their surfaces act as vectors that concentrate and transport co-contaminants through ecosystems in various forms including films and fragments.
