Summary
Introduction. Both lead and cadmium present one of the greatest threats to life on earth. Toxic poisoning with lead and cadmium of present-day population of children and youth is becoming a social and medical problem.
Aim. This research has two objectives: establishing the levels of concentrations of lead and cadmium in a group of young girls at the age of development and sexual maturation, and clinical assessment of magnesium supplementation effects on decreasing of the content of lead and cadmium.
Material and methods. Research was conducted on a group of 16 girls aged 9-20 years. Over a 6 month period they were given magnesium supplementation in a form of dissolved magnesium pidolate in sachets of 140 mg, twice a day.
The level of toxicity was assessed on the basis of laboratory tests on hair lead and cadmium contents before and after magnesium supplementation.
Results. In all tested girls the presence of lead and cadmium was observed. Half-year supplementation with magnesium caused a decrease of lead level concentration in ten girls (p < 0.15) and the decrease of cadmium concentration level in all tested girls (p < 0.0029).
Conclusions. Supplementation with magnesium plays a significant role in prevention and treatment of disturbances caused by lead and cadmium toxins.
