Incidence of 49 elements in the blood and scute tissues of nesting hawksbill turtles (Eretmochelys imbricata) in Holbox Island

Due to progressive urban development along the Mexican Caribbean coastline, it is crucial gauge impact of anthropogenic contamination marine ecosystems through biomonitoring procedures. In current study, we quantified concentration 49 inorganic elements in blood and scute tissues clinically healthy nesting hawksbill sea turtles (Eretmochelys imbricata). The were classified into four groups: Group A: essential mineral with toxic potential; B: non-essential high toxicity; C: minority Trace Elements (TE); D: rare-earth (REE) other TE. Almost all samples both showed perceptible levels elements. only element identified a correlation between was arsenic (As), which could indicate fast excretion this type keratinized tissue. bio-accumulation complex process, requiring simultaneous examination different evaluate exposure. Our study reinforces usefulness tissue as non-invasive sampling technique for evaluation persistent pollutants turtles.
