HUMAN AS A BIOTIC FACTOR IN ACCUMULATION OF MICROELEMENTS WITH WEAK TOXICITY IN BONE AND MUSCLE TISSUE OF BACKGROUND REPTILE SPECIES IN THE ABSHERON PENINSULA

The accumulation and amount of microelements with weak toxic effects have been studied in bone and muscle tissue of following Reptile species - Water snake (Natrix tessellata Laurenti, 1768), Mediterranean turtle (Testudo graeca L.1758) and Caspian bent-toed gecko (C.caspius E. 1831).Studied microelements are cobalt Co, molybdenum Mo, manganese Mn, and chromium Cr. All the four microelements that we have studied are mostly accumulated in the body of Caspian bent-toed gecko. It should be noted that the Caspian bent toed gecko is very small and more functionally active among background reptile species that we studied. Its occurrence in oil, gas wells and in areas exposed to technogenic and antropogenic pollution, indicates its plasticity and resistance to toxic microelements.
