英文摘要	The odontocetes are at the top of the trophic chains, and because they accumulate numerous compounds throughout life, they are considered as bioindicators of ecosystem contamination. This study aimed to analyze the concentrations of trace elements of the short-beak common dolphin (Delphinus delphis) and Fraser's dolphin (Lagenodelphis hosei) from the Southwestern Atlantic Ocean. Regardless of the tissue and the species, the average concentration of silver was the lowest. The highest concentration in the kidney was cadmium, while in the liver it varied between selenium and total mercury according to the species. The bioconcentration process was present in relation with the age and standard length in common dolphins. Additionally, Se–HgT molar ratios differed among species. This study provides new information on the current state of pollution by trace elements in common and Fraser's dolphins in the Southwest Atlantic, and it serves as a complement to the work in tropical waters. © 2019 Elsevier Ltd
