En este estudio analizamos la exposición de galápagos leprosos a plomo (Pb) y mercurio (Hg) en las zonas mineras del sur de Ciudad Real con el propósito de validar el uso de heces y de piezas desprendidas de la capa epidérmica del caparazón como métodos no invasivos de monitorización de estos metales.
