For this purpose, the femur and both tibias of control female rats and those exposed to Cd (1\u2009mg Cd l<jats:sup>\u22121<\/jats:sup> in drinking water for 24\u2009months since weaning) were assigned to geometric, densitometric (bone mineral content, BMC, and density, BMD), radiographic and biomechanical studies as well as assessing their chemical composition. The exposure to Cd disturbed mineralization (decreased BMD and minerals content, including calcium, magnesium, zinc, copper and iron) and weakened the biomechanical strength of the femur and tibia, enhancing their fragility. The <jats:italic>Z<\/jats:italic>\u2010score values for the BMD revealed osteopenia of the femur and tibia in 20 and 30% of the Cd\u2010exposed female rats, respectively, and osteoporosis in 80 and 70%, respectively. In 30% of the Cd\u2010exposed animals, femoral neck fracture was evident in the radiographic picture. The findings seem to confirm the hypothesis that a low exposure to Cd during the lifetime may be an important risk factor for osteoporosis and fractures of long bones, and especially for femoral neck fracture in elderly women. The results indicate that greater attention should be paid to Cd as an environmental risk factor for the increasing rate of osteoporosis and bone fractures in old population.
