“…Some studies highlight the existence of traces of metal such as chromium, manganese, zinc, nickel and vanadium, on sediments at Penguin and King George islands (Guerra et al, 2011;Santos et al, 2005) and concentrations of polycyclic aromatic hydrocarbons (Barroso, 2010).…”

The gastropod Nacella concinna is common in the littoral zone of the Antarctic Peninsula. This invertebrate has great importance in terms of biomass for the region, being a potential prey for the Kelp gull Larus dominicanus. They have a tendency to opportunism, but can select large shells when they are available. This study aims to evaluate Nacella concinna shells morphometry and access whether the length, width, height and the apex differ significantly between sampling sites. Shells were collected manually in three islands of the South Shetlands: Elephant, Penguin and King George, at Kelp gull breeding and feeding points. The shells measurements were made with a caliper at the laboratory. Shells morphometric variables were compared between the three islands through discriminant analysis, with the function generated by it, an ANOVA was made. There were significant differences (p < 0,001) among the samples measured. All shell measurements were higher for Elephant Island. The variation found in shells among the three islands may have been influenced by differences in environmental conditions.

“…Fonte: Barroso (2010) Portanto, a predominância de HPAs leves e homólogos alquilados é esperada para a região antártica uma vez que esses compostos são geralmente atribuídos ao uso de diesel especial como combustível nas estações de pesquisa.
