PublicationOpen Access¿Sabías que...?(2024-04-16) Romero García, Diego; Facultad de Veterinaria- PublicationOpen AccessHigh Levels of Blood Lead in Griffon Vultures (Gyps fulvus) from Cazorla Natural Park (Southern Spain)(Wiley, 2005-04-08) Godino, A.; Jiménez, P.; García Fernández, Antonio Juan; María Mójica, Pedro; Martínez López, Emma; Romero García, Diego; Ciencias SociosanitariasThe blood lead of 23 griffon vultures (Gyps fulvus) trapped in 2003 was analyzed in order to evaluate exposure to lead in the vulture population of Cazorla Natural Park (in southern Spain). In 2001 the use of leaded gasoline in vehicles was banned in the European Union; however, lead ammunition is still used in Spain in big-game hunting for red deer, fallow deer, mouflon, and wild boar, which are ingested by vultures from September to March. The mean concentration of lead in blood was 43.07 6 31.96 g/dL with a range of 17.39–144.80 g/dL. Only two vultures had lead levels below 20 g/dL, and two others had blood lead concentrations close to 150 g/dL. In view of the results, we think the population of vultures from Cazorla Natural Park is suffering subclinical exposure to lead, with some individuals exposed to high toxicity risk. We concluded that ingestion of lead in the metallic form alone is sufficient to produce these blood lead concentrations, and we recommend the prohibition of lead ammunition for big-game hunting in order to preserve the vulture population.

- PublicationOpen AccessNew method for imputation of unquantifiable values using Bayesian statistics for a mixture of censored or truncated distributions: application to trace elements measured in blood of Olive Ridley sea turtles from Mexico(MDPI, 2022-10-25) Salvat-Leal, Inmaculada; Cortés-Gómez, Adriana A.; Girondot, Marc; Romero García, Diego; Ciencias SociosanitariasOne recurring difficulty in ecotoxicological studies is that a substantial portion of concentrations are below the limits of detection established by analytical laboratories. This results in censored distributions in which concentrations of some samples are only known to be below a threshold. The currently available methods have several limitations because they cannot be used with complex situations (e.g., different lower and upper limits in the same dataset, mixture of distributions, truncation and censoring in a single dataset). We propose a versatile method to fit the most diverse situations using conditional likelihood and Bayesian statistics. We test the method with a fictive dataset to ensure its correct description of a known situation. Then we apply the method to a dataset comprising 25 element concentrations analyzed in the blood of nesting marine turtles. We confirm previous findings using this dataset, and we also detect an unexpected new relationship between mortality and strontium concentration
- PublicationRestrictedCarapace asymmetry: A possible biomarker for metal accumulation in adult olive Ridleys marine turtles?(Elsevier, 2018-02-20) Cortés-Gómez, Adriana A.; Girondot, Marc; Romero García, Diego; Ciencias SociosanitariasThe Olive Ridley marine turtle (Lepidochelys olivacea) is characterized by individual morphological variability in the number and shape of scutes. The influence of pollutants on developmental instability and one of its con- sequences, the asymmetry of individuals, has been demonstrated in several species, especially invertebrates and some birds. However, the use of this asymmetry as a biomarker of contamination in adult individuals has never been explored. We developed an index to quantify developmental instability (DIx) based on the number and relative size of costal carapace scutes. The link between DIx and inorganic elements concentrations was explored in various tissues of stranded turtles from the Southern Mexican Pacific. The relationships between adult contamination and DIx could directly or indirectly reflect (i) the disruption of metal elimination in the adult stage dependent on embryonic perturbation and thus determining DIx, (ii) the difference in metal absorption de- pendent on DIx status, or (iii) DIx linked to other unknown factors.
- PublicationOpen AccessHeavy metals in tissues from loggerhead turtles (Caretta caretta) from the southwestern Mediterranean (Spain)(Elsevier, 2009-02-02) Hernández-García, Alejandro; Castillo, Juan J.; Bellido, Juan J.; García Fernández, Antonio Juan; Gómez Ramírez, Pilar; Jiménez Montalbán, Pedro Javier; María Mójica, Pedro; Martínez López, Emma; Romero García, Diego; Ciencias SociosanitariasCadmium, lead, copper, and zinc were measured in tissues of 21 loggerhead turtles (Caretta caretta) from the southwestern Mediterranean coastline. Mean concentrations (dry weight) of essential elements (Zn and Cu) were 107 and 21.6 μg/g in liver, 27.9 and 3.8 μg/g in kidney, 65.4 and 5.0 μg/g in pectoral muscle, 11.1 and 3.45 μg/g in brain, and finally 19.2 μg/g and undetected in bone, respectively. Mean concentrations of heavy metals (Cd and Pb) were 23.4 and 2.8 μg/g in liver, 31.5 and 0.5 μg/g in kidney, 0.2 and 0.3 μg/g in pectoral muscle, 0.2 and 0.7 μg/g in brain, and undetected and 1.2 μg/g in bone, respectively. Metal concentrations were similar to other studies conducted on Mediterranean turtles. However, cadmium concentrations varied widely among individuals, which has been associated with potential sources of cadmium in Mediterranean Sea. This is the first study into metal accumulation in tissues of loggerhead turtle from Spanish Mediterranean coastline.
