Comparison of Cytotoxicity and Photocatalytic Properties of Iron Vanadate Nanoparticles with Commercial Catalysts: For the Degradation of Microplastics and Bacterial Inactivation Application

Researchers compared iron vanadate nanoparticles with commercial photocatalysts for degrading microplastics and inactivating bacteria using solar light. The iron vanadate catalyst showed moderate cytotoxicity at low concentrations and demonstrated effective photocatalytic activity against both microplastics and bacterial contamination. The study suggests that iron vanadate nanoparticles could serve as a dual-purpose water treatment material for addressing microplastic pollution and microbial contamination simultaneously.

Impact of Microplastics on the Environment, Human Health and Their Removal

Detection, characteristics, and some influencing factors of MPs in rainfall

Are fish larvae contaminated before they start eating? First evidence of microplastic contamination in the yolk-sac of wild fish larvae

Researchers investigated microplastic contamination in wild fish larvae of two species — European sardine and common goby — from the Douro Estuary in Portugal, examining whether contamination begins before active feeding commences. They found microplastics present even in yolk-sac stage larvae that rely entirely on endogenous feeding, providing the first evidence that larval fish are contaminated before they begin eating.

Behavioral and biochemical alterations in zebrafish model suggests AChE as a potential target for cytarabine neurotoxicological effects

Researchers exposed zebrafish eggs to the anticancer drug cytarabine and found that while it caused no mortality or teratogenicity up to 100 mg/L, it reduced locomotor activity under dark conditions, increased lipid peroxidation and acetylcholinesterase activity, and inhibited catalase, with molecular docking simulations confirming direct cytarabine binding to acetylcholinesterase as a likely mechanism of neurotoxicity.

Plastics and Microplastic: A Major Risk Factor to the Soil, Water and Marine Environments

This paper reviews the risks microplastics pose to soil, freshwater, and marine environments, including effects on soil microbial communities, aquatic organisms, and human health through the food chain. It identifies bacterial communities and biotransformation processes as critical factors in understanding microplastic fate.

Exploring the Synergistic Effects of Agitation on the Interaction Between Nanoparticles of Polyethylene and Benzophenone in Microalgae <i>Tetraselmis</i> sp.

This study examined how agitation levels affect the interaction between polyethylene nanoparticles and the insecticide benzophenone in microalgae, finding that agitation significantly altered toxicity outcomes. The results suggest that physical conditions in aquatic environments influence how microplastics and co-pollutants affect marine organisms.
