The ingestion of anthropogenic microparticles by fish is an emerging global concern, with significant knowledge gaps in ecosystems such as mangroves. We analyzed the gastrointestinal tract contents of 736 juvenile fish representing 20 species from different trophic guilds across three estuaries, sampled during two seasons (dry and rainy), within the largest mangrove area in South America. A total of 1516 food items were identi...

In the last few years, several studies have investigated microplastics (MPs) in marine ecosystems, but data monitoring and assessing the occurrence in freshwater environments are still scarce. The present study aims to investigate the occurrence, distribution, and chemical composition of MP pollution in Vesijärvi lake and Pikku Vesijärvi pond close to the city of Lahti (Finland) in winter. Sediment, snow, and ice core samples...
