First Evidence of Microplastic Contamination in Antarctic Fish (Actinopterygii, Perciformes)
Microplastic (MP) pollution in Antarctica is a hot topic that has gained increasing attention in recent years. However, information regarding MP pollution in Antarctic fishes is currently very limited. The present study provides the first evidence of the occurrence and characteristics of MPs in spec...

Microplastic (MP) pollution in Antarctica is a hot topic that has gained increasing attention in recent years. However, information regarding MP pollution in Antarctic fishes is currently very limited. The present study provides the first evidence of the occurrence and characteristics of MPs in species from five families of the order Perciformes, from the Amundsen Sea (AS) and Ross Sea (RS), Antarctica. MP abundances within the order Perciformes were at a medium level on a global scale, but were higher than those reported in other Antarctic organisms. The detection rate and abundance of MPs in the order Perciformes from the RS (50% and 1.286 items individual−1) were both higher than those from the AS (36% and 1.227 items individual−1). Moreover, the major composition and size of MPs were, respectively, polyacrylamide (PAM) and 100–200 μm in the RS, but rayon and 500–1000 μm in the AS.
