Complete blood counts (n=566) and serum biochemistry (n=426) were assessed in seven coastal seabirds species that underwent rehabilitation along the southeastern and southern coast of Brazil from Saquarema, Rio de Janeiro State (22°56'16.44″S, 42°18'24.16″W) to Laguna, Santa Catarina State (28°29'43″S, 48°45'39.

- The study investigated the presence of polycyclic aromatic hydrocarbons (PAHs) in Spheniscus magellanicus (Magellanic penguins) along the coast of São Paulo, Brazil, by analyzing their biliary metabolites.
- 79 penguins, either found dead or admitted to rehabilitation, were tested for metabolites of three specific PAHs: naphthalene, phenanthrene, and benzo[a]pyrene, using advanced liquid chromatography techniques.
- Results showed a range of total metabolite concentrations, primarily consisting of naphthalene metabolites, with benzo[a]pyrene detected in only two samples, marking a pioneering effort in assessing PAH bioavailability in this species.
The causes of the beaching and death of sea turtles have not been fully clarified and continue to be studied. Mild, moderate and severe lesions caused by spirorchiidiosis have been seen for decades in different organs and were recently defined as the cause of death of a loggerhead turtle. In the present study, eyes and optic nerves were analysed in green sea turtles with spirorchiidiosis and no other debilitating factors.

Because they nest in beaches along the coastline and islands, green turtles are susceptible to fishing and accidental ingestion of anthropogenic debris.
