[Evaluation of lead poisoning in an exposed pediatric population before and following control of the source].
In the surroundings of a large lead mill, which emitted in the 70 years up to 250 t of lead per year and where the maximum allowable daily immission concentrations of 0.7 microgram/m3 were exceeded by a factor of 20-30, in children mean blood levels above 45 micrograms/100 ml blood were determined. At the beginning of the 80 years the mill had modernised the filter constructions. The emission was decreased to 10% of the original value. The immissions decreased by 50% and the blood lead level in children by 10 to 20%. It could be shown, that the soil was furthermore contaminated and vegetables and fruits contained increased lead levels. Additional measures are to be realised to diminish exposure. The situation described is an example for the long latency of positive changes in the environment and in the health state of the population following environmental preventive measures.
