Persistent organic pollutants and contaminants of emerging concern in spinner dolphins (Stenella longirostris) from the Western Atlantic Ocean.

Article Synopsis
- Scientists studied spinner dolphins from the Fernando de Noronha Archipelago to see if they had harmful chemicals called POPs and CECs in their bodies.
- They took fat samples from 37 dolphins and used special lab tests to find out the levels of these chemicals.
- The levels of harmful substances found in these dolphins were lower than what has been seen in dolphins from other oceans, but even low levels can still make it harder for them to stay healthy, especially with more tourists visiting the area.
The Atlantic spotted dolphin (Stenella frontalis) is endemic to tropical, subtropical, and warm temperate waters of the Atlantic Ocean. Throughout its distribution, both geographic distance and environmental variation may contribute to population structure of the species. In this study, we follow a seascape genetics approach to investigate population differentiation of Atlantic spotted dolphins based on a large worldwide dataset and the relationship with marine environmental variables.

In the past, it was impacted by both chlorinated pesticides and polychlorinated biphenyls (PCBs) due to its natural location. The marine tucuxi dolphin (Sotalia fluviatilis) is a top predator in this ecosystem and can be found year round in Cananéia estuarine waters that represent an important nursing area for the species.
