Various fluoride compounds are widely used in industry. The present risk assessment study was conducted using a series of inorganic binary fluorides of the type XFn, where Xn = Na+, K+, Li+, Mg2+, Ca2+, Sr2+, Ba2+, Al3+, Nd3+, La3+, Ce3+, Sm3+, Gd3+, Y3+, Yb2+, and Zn2+. The aqueous solutions of these salts were orally administrated to 16 experimental(More)
Rubidium has been considered to be nontoxic. Its use includes thin film on glass deposition and as medical contrast medium. Recent technology innovations also involve the use of rubidium, but there is limited information about the biological effects of its various compounds. In the present risk assessment study, a series of rubidium compounds with different(More)
