Resumen
This study was performed in order to determine the level of lead (Pb), cadmium (Cd), Zn and Cu in 170 bone samples of the prehispanic population of the Canary Islands, 4 belonging to the 18th century, and 8 modern samples who served as controls. Prehispanic individuals from El Hierro showed the lowest bone Pb values of all the Archipielago (0.72 ± 1.01mg/kg), significantly different (F=6.9, p<0.001) from the values obtained for the population of other islands, as Tenerife (4.87 ± 5.36mg/kg) or Fuerteventura. Bone lead was higher in the 18th century population than in the prehispanic one, but lower than the modern controls. On the contrary, bone Cd, although slighly lower in the ancient population groups, was not significantly different when compared with the modern one. In addition, no differences were observed in bone Cd among the ancient population of the different islands. Bone lead-but not cadmiun- kept an inverse significant relationship with the distance of the burial site both to the distance of the burial site both to South Spain (r-0.309) and Atlantic Marocco (r = -0.279, p<0.001 in both cases).
