Resum
Microdebris are ubiquitous and the Southern Ocean is no exception. Despite the recent increment in Antarctic studies assessing this threat, there is still scarce information available. Here, we quantified the microdebris in surface water, and their distribution within two bays of Livingston Island (South Shetlands, Antarctica). The two studied bays included one with human presence and one pristine, barely visited. Microdebris pollution was found in all samples with a mean concentration of 0.264 ± 0.185 items/m3. Fibres (82.19 %) were the main item, with polyester (61.67 %) as the main plastic polymer, followed by nylon (29.54 %). No differences in the distribution pattern were observed, with microdebris being homogeneously distributed along the two bays. Our results suggest that nearshore waters of Livingston Island are prone to the accumulation and retention of microdebris. The composition of the microdebris also points to Antarctic local activities as principal contamination contributors.
