Abstract

Abstract This study shows the abundance of contamination by plastic microfibers (PMs) and the first record of contamination by PMs in bats. Additionally, we tried to understand the mechanism of the environmental contamination of bats. Therefore, the digestive and respiratory tracts of 25 species of adult bats were extracted for analysis. Bats were captured in different locations in the Brazilian Amazon (Altamira, Bragança, Brasil Novo, Medicilândia, Nova Timboteua, Placas, Uruará and Vitória do Xingu, all in the state of Pará). The results showed that all species were contaminated with PMs in at least one of the analyzed systems. For the digestive system, the form of contamination occurs through bioaccumulation and biomagnification by the ingestion of contaminated food or water. While for the respiratory system, contamination occurs through the inhalation of PMs suspended in the atmospheric air. The different foraging characteristics of bats, the type of capture strategy for this food, and the type of habitat reinforce the idea that plastic contaminants are present in all environments.
