The study found that the levels of persistent organic pollutants in spinner dolphins from the Fernando de Noronha Archipelago are lower than those in dolphins from the Indian and Pacific Oceans. Despite the relatively low levels of contaminants, the presence of chemicals poses an additional stressor to these marine mammals.
The presence and distribution of persistent organic pollutants (POPs) and contaminants of emerging concern (CECs) were evaluated in spinner dolphins (Stenella longirostris) from the Fernando de Noronha Archipelago (Western Atlantic Ocean). Blubber samples (n = 37) were Soxhlet extracted and analyzed using gas chroma-tography tandem mass spectrometry. The levels of POPs reported in this study are far below those previously reported in spinner dolphins from the Indian and Pacific Oceans. Despite relatively low levels of contaminants, the presence of chemicals represents an additional stressor to these marine mammals, which are subject to increasing anthropogenic pressures, especially regarding tourism activities, in Fernando de Noronha.
