Identification of marine microplastics collected in the Canary Islands: coastal and oceanic samples
AI summary Read the abstract
This research characterized airborne microplastic deposition in the city of Zagreb, Croatia, using passive collectors over multiple seasons, finding year-round particle accumulation. Fiber types dominated samples, with deposition rates comparable to Western European urban measurements, indicating regional atmospheric transport contributes alongside local emission sources.
The existence of microplastic in the water column between 50 and 300 meters depth in the Atlantic Ocean is reported for first time. To carry on this study, some cruises near Canary Islands were done. Microplastic concentrations could be related with the density profiles. The samples are taken at different depths in a range of between 0 to 300 meters deep. A rosette with a CTD and 23 Niskin bottles were used to take these samples. Between 100 and 280 meters deep, the highest concentrations of microplastics were found. \n On the other hand, we have used samples of coastal microplastic, to study the colour variation of the material due to degradation process. With PANTONE® Studio app it was determined and compared with the plastic composition (determined using FTIR) and its colorimetry (through a colorimeter). With all this data we have calculated the yellowness index value of each sample and compared with Pantone code colour. The values of yellowness index are in a range between the values 17,722 and 127,874%. The optimization of this methodology lets the determination of yellowness index in a simpler way using just a mobile app.

Microplastics in the Marine Ecosystems: Identification and Impacts
AI summary Read the abstract
Tiny plastic particles called microplastics, broken-down bits of everyday plastic waste, are showing up along India's coastlines, and this review paper rounds up what scientists have found so far. While research on their health effects is still catching up, these particles are known to persist in the environment and can enter the food chain through seafood, raising concerns about long-term exposure for coastal communities. The authors point out that India still needs a lot more research to fully understand how serious this problem is and what it means for people's health.
Analysis of Marine Microplastics in the Water Column Sampled up to 300 M Depth
AI summary Read the abstract
Researchers sampled ocean water down to 300 meters depth and detected microplastics throughout the water column, demonstrating that plastic pollution extends well below the surface and is not limited to the shallow or coastal zones most commonly studied.
Microplastics in the pelagic environment around oceanic islands of the Western Tropical Atlantic Ocean
AI summary Read the abstract
Researchers confirmed for the first time that microplastic pollution is present in the surface waters around three ecologically important island groups in the tropical western Atlantic Ocean. The particles — including fragments, films, paint chips, and fibers — come from both land and ocean sources, threatening marine species in these sensitive ecosystems.

AI summary Read the abstract
Researchers surveyed microplastic abundance and polymer types across multiple compartments of a Mediterranean marine environment, documenting their presence from the sea surface to beach sediments and within marine organisms. The study adds to growing evidence that microplastics are pervasive throughout Mediterranean coastal ecosystems.
