Abstract Rodents are a group of mammals that have always been considered as bio-indicators for ecosystems' health. This study has been designed to do so and to investigate the changing way of element absorption measurements like Cadmium, Vanadium, Chromium, and Zinc in the muscle and liver of Meriones persicus and Ellobius lutesence in the vicinity of the oil refinery and petrochemistry of Shazand. Totally 18 individuals from M. persicus and 15 individuals belong to the E. lutesence have been sampled, and target tissues have been taken and analyzed in the corresponding lab. Our results showed that Cadmium, Vanadium, and Chromium were highly accumulated in Persian jirds' muscle tissue and showed a tapering trend in those areas where are far from the refinery factory. Zinc has been detected in a high amount in the liver of jirds as well. Based on the distance from the oil refinery factory, Cd and Zn were detected in the muscle tissue of Mole voles and comparatively in a lower amount in the hepatic tissues.
