An assessment of microplastic contamination in freshwater fish from the Upper Doce River basin (Minas Gerais, Brazil): a 2003 baseline study
Microplastics (MPs)—plastic particles smaller than 5 mm—have become a growing environmental concern due to their pervasive presence in aquatic ecosystems. This study investigates the presence of MPs in freshwater fish specimens collected in 2003 in a small urban pond (Upper Doce River basin, Brazil). From the 744 f...
