Lead concentrations in some organs of the rat meriones libycus and its parasite hymenolepis diminuta from Riyadh City, KSA

الملخص EN

In the present study, the tape worm Hymenolepis diminutive was chosen to estimate lead bioaccumulation in an urban area highly polluted with lead (the industrial area) and another less polluted one (Al-Karj road) at Riyadh City, K.S.A.

Lead concentrations were found 38 to be 32 and 15 times in the parasite (H.

diminutive) than in the intestine, liver and kidney of the host (Merinos libycus).

Thus, the proposed model of cestode parasite-rat as bio-indicator of lead pollution seems to be promising in the terrestrial habitat.
