[Lead detoxication effect of a combined calcium phosphate and ascorbic acid therapy in pregnant women with increased lead burden (author's transl)].

In former papers it was stated that the fetus can be exposed a considerable burden by traces of heavy metals and that a combined therapy with calcium phosphate and ascorbic acid has a good detoxifying effect. In fourty lead-burdened mothers who were treated in this way the excretion of 5-aminolevulinic acid in urine decreased by 65%, the lead content of placenta by 90% and the lead content of mother's milk by 15% compared with a control group without treatment. The cadmium content of the placenta was reduced to 4% of the content in untreated mothers.
