Assessment of microplastic pollution in sand beach from SW Atlantic coast (Argentina) using a regional harmonized method.
AI summary Read the abstract
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.
Argentina ranks among the Latin American countries with the highest per capita plastic consumption, producing 1,162,000 tons annually and importing an additional 882,600 tons. This high level of consumption leads to the accumulation of plastic waste in both terrestrial and aquatic environments. The environmental assessment of plastic debris pollution is essential for identifying the sources and fate of these particles. Microplastics (MPs; particles

Researchers analyzed microplastic and antifouling paint particle contamination in coastal sediments at three locations along the southwestern Argentine Atlantic coast. Microplastic concentrations ranged from about 20 to over 1,000 particles per kilogram of sediment, with fibers and small particles dominating. The study provides baseline pollution data for an understudied region of South America, showing that even areas with varying levels of industrial development share significant microplastic contamination.

Microplastics in brazilian marine environments: a study on beaches in São Francisco do Sul - SC
AI summary Read the abstract
Beach surveys along São Francisco do Sul in southern Brazil confirmed widespread microplastic presence in coastal sediments, with polymer composition reflecting regional plastic waste streams. The study adds to the body of evidence that Brazilian coastlines are significantly contaminated and calls for national monitoring standards to track and manage the problem.
