Microplastics pollution in coastal water, rivers and soil: monitoring, assessment and remediation
AI summary Read the abstract
Tiny plastic particles are turning up everywhere, from ocean water and rivers to the animals living in them, and this collection of studies shows they're not just an environmental nuisance. In lab mice, microplastics disrupted gut bacteria, reduced protective gut mucus, and messed with liver fat processing, hinting that eating these particles (which we likely do through seafood and water) could affect digestion and metabolism in people too. While more research is needed to confirm these effects in humans, the findings suggest microplastic pollution may be a health concern worth taking seriously, not just an ecological one.
Large quantities of MPs (0.02-0.3mm) were found in the surface water of South China Sea.• Large-scale distribution characteristics of MPs in a marginal sea were presented, with topographical inventory estimation.• The distribution pattern of MPs in this study presented a strong terrestrial impact.• Improvement of the method for smaller MPs are imperative. UAM-Master Inland Water Quality Assessment , December 2019, Madrid• Microplastic ingestion by riverine macroinvertebrates was assessed over South Wales.• Microplasticswere identified in approximately 50% of macroinvertebrate samples.• Ingestion of microplastics was observed in all taxa, across all sites.• No difference in microplastic burden was observed downstream of sewage treatment UAM-Master Inland Water Quality Assessment , December 2019, Madrid• An assessment of MP in stormwater retention ponds across various landscapes.• Commercial and industrial areas emitted more MP than residential and highway areas.• PVC, PS, PP, PE and polyester were the most common polymers found.• PVC had the largest particle size and mass. UAM-Master Inland Water Quality Assessment , December 2019, Madrid• The contribution from ingested MPs to overall uptake of HOCs by fish was evaluated.• KMP/SIF and Kom/SIF were determined for HOCs using a tree-phase partitioning method.• HOCs leaching from MPs in artificial gut fluid was compared with model predictions.• The contribution of plastic-bound intake was assessed using a fish bioaccumulation model.• The results suggest that the role of ingested MPs may play as "dilution" for HOCs. UAM-Master Inland Water Quality Assessment , December 2019, Madrid• Polystyrene microplastic decreased the secretion of mucin in gut of mice.• Polystyrene microplastic induced gut microbiota dysbiosis in mice.• Polystyrene microplastic induced hepatic lipid metabolism disorder in mice. UAM-Master Inland Water Quality Assessment , December 2019, Madrid• Microplastics could interact with microorganisms as well as gut microbiota.• Microplastics may affect host health through effects on gut microbiota.• Effects of microplastics on gut microbiota need more attention.

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms
AI summary Read the abstract
Tiny plastic particles from our food, air, and water may be doing more than just passing through our bodies, this review of existing research suggests they can irritate the gut lining, trigger inflammation, and throw off the balance of healthy gut bacteria. While scientists haven't yet nailed down exactly how much exposure causes harm or the precise mechanisms involved, the evidence so far suggests these ever-present plastic particles could be a hidden contributor to digestive health problems, making it a research area worth watching.
Microplastics Pollution in Freshwater and Marine Fisheries: Sources, Bioaccumulation, Ecotoxicological Impacts, and Sustainable Mitigation Strategies
AI summary Read the abstract
Tiny plastic particles are showing up everywhere in our lakes, rivers, and oceans—and fish are eating them, with the plastic building up mainly in their gut and gills but sometimes spreading to other tissues too. This review of existing research shows these particles can cause stress, inflammation, and other health problems in fish, and since we eat seafood, that raises real questions about what ends up on our plates. The good news: the paper points to practical fixes, like better waste management and fishing practices, that could cut plastic pollution before it reaches our food supply.
Microplastics Pollution in Freshwater and Marine Fisheries: Sources, Bioaccumulation, Ecotoxicological Impacts, and Sustainable Mitigation Strategies
AI summary Read the abstract
This review pulls together existing research showing that tiny plastic particles (microplastics) are now found throughout rivers, oceans, and the fish and seafood we eat, mostly in their guts and gills but sometimes in other tissues too. In lab studies, these particles have been linked to stress, inflammation, and other health problems in fish, especially when combined with other pollutants like heavy metals—raising real questions about what this means for the safety of seafood on our plates. The good news: researchers say better waste management, fishing practices, and pollution monitoring could help reduce this problem before it gets worse.
Microplastics in the environment: sources, impacts, and strategies for mitigation
AI summary Read the abstract
Tiny plastic bits called microplastics, created when everyday plastic items break down, have been found in surprising places, including our blood, fish, soil, and water, and scientists are still working to understand exactly how harmful they are. This review pulls together what researchers currently know about where these particles come from, how they spread, and what methods might remove them, while pointing out that we still lack solid answers on their long-term health effects and the best ways to clean them up. The takeaway: microplastic pollution is a growing concern worth watching, even though the science on its full impact to our bodies is still catching up.
