Some oxidation states of chromium are indeed toxic, but the most stable form is chromium(III), which is harmless enough that you can buy it as a supplement. Nickel also occurs naturally in soil and many foods and is not accumulating in the body. The kidneys can remove it. Only large doses are problematic.
