Trace elements and lipidomic datasets of stranding samples in the blubber of Turpsios truncatus from the Yucatan Coast: Association with biological features

Trace elements are the result of natural and anthropogenic sources. Some of them are toxic causing alterations in the properties of membranes and produce lipid peroxidation. The dataset presented here is associated with the research article paper entitled “Trace element and lipidomic analysis of bottlenose dolphin blubber from the Yucatan coast: Lipid composition relationships”. In this article, we presented the trace element concentrations found in blubber and their comparison with other studies. Lipidomic characterization of bottlenose dolphin blubber and their association with trace elements and the differences related to biological characteristics. This data provides a correlation analysis between trace element concentrations and lipid species related to biological characteristics. We used Spearman correlation analysis to identify the association with body length and Wicolxon rank-sum test to determine differences in lipids related to stranding code, growth stage and stomach content. The data indicates that Cr, Cd and Zn concentrations were higher compared to other studies. Cr, Co, As and Cd were found in higher concentration in larger organisms. A decrease in some ceramides, sterols, glycerolipids and phosphatydilglyceros related to higher dolphins were found. Decomposition causes a decrease in phosphoethanolamines. Organisms with empty stomachs showed higher concentrations of phosphoethanolamines suggesting a preferential metabolism of energy-rich lipids over structural lipids. The information in these datasets may contribute to understanding the potential associations of trace element, lipid and their associations with biological characteristics.
