Assessment of microplastic pollution in sand beach from SW Atlantic coast (Argentina) using a regional harmonized method.
Researchers assessed microplastic pollution on sand beaches of the SW Atlantic coast of Argentina using a regionally harmonised sampling and analysis method, characterising particle morphology, colour, size, and polymer type in a country that produces over 1.16 million tons of plastic annually. The study aimed to identify sources and fate of beach microplastics and establish a standardised baseline for future regional monitoring.
Detection of microplastic hotspots in beach sand for national surveys using fluorescence microscopy and infrared spectroscopy: Case study on the Catalan coast
Researchers characterized microplastic contamination across 70 intertidal sand samples spanning 580 kilometers of Catalan coastline, using both fluorescence microscopy and infrared spectroscopy. They found that microplastics smaller than 0.5 mm were dominated by fibers while larger particles were mostly fragments, with polyethylene, polypropylene, and polyester being the most common polymers. The study demonstrates that Nile Red fluorescence staining can serve as an effective screening tool for identifying microplastic hotspots in national beach surveys.
