ANTHROPOGENIC PARTICLES IN THE GASTROINTESTINAL TRACT OF Cynoscion acoupa AND Balistes capriscus SOLD IN MARKETS OF SANTOS, SÃO PAULO

Abstract

Anthropogenic particles (APs), such as microplastics (>5 mm), are ubiquitous in various environmental matrices and can be ingested by fish. To assess the contamination of fish intended for human consumption, this study aimed to analyze the presence of APs in the gastrointestinal tract (GIT) of species commercialized for human consumption in Baixada Santista, SP. Specimens of Cynoscion acoupa and Balistes capriscus were measured and weighed, and the GIT of each individual was visually analyzed using a stereoscope. The APs were classified according to size, shape, and color. APs were recorded in both species, totaling 80% for both species. The dimensions of the APs ranged from 0.5 to 3.5 mm, with a predominance of fiber shape and blue coloration. These results raise serious concerns regarding potential risks to public health and food safety, highlighting the importance of continuous monitoring and stricter policies to mitigate marine pollution.
