A group of 6 male rats received for 4 weeks a diet supplemented
with 200 mg Pb/kg (as lead acetate) together with 5 mg Cd/kg (as
cadmium hydroxide). Furthermore, 40 g alginic acid/kg of diet was
added. A control group of 10 male rats received the Pb/Cd
supplemented diet without the addition of alginic acid. Deposition
of Pb and Cd in liver, kidneys and femur was measured. A reduction
of growth was seen in the alginic acid group. Alginic acid had no
effect upon Cd deposition, but Pb content in femur and kidneys was
doubled.
