We investigated 239 children from ecologically polluted regions and 70 children from ecologically clean area. Children’s age is from 3 to 18 years, sex – 48, 0 % boys and 52, 0 % – girls. Level of calcium and phosphorus in the blood and urine in these children before and after the treatment was analyzed by biochemistry examination. Bone mineral density and bone system degree of changes were measured by ultrasound densitometry. Level of calcium and phosphorus in the blood in observed children from polluted region was reduced. Level of calcium in the urine was increased in the majority of observed children from the radiation polluted region and in children from the chemistry polluted regions. And level of phosphorus in the urine was increased in the majority of observed children from chemistry polluted regions. The level of the bone mineral density in these children was reduced. All the indicators were normalized after the treatment.
