[Results of blood examination in Braubach 1990]

In May 1990 491 persons living next to a metallurgical plant in Braubach were examined concerning the concentration of heavy metal in the blood. On account of a modification of the plant, the blood-lead concentration of these persons was, in comparison with former examinations, significantly decreased. Subjects with vocationally exposed relatives showed enhance values. This is probably caused by the penetration of pollutants into the domestic sphere. Contamination of blood by different heavy metals could not be ascertained. Examined hemapaetic parameters were not affected. In scopes with minor lead concentrations in blood indications have proved that the lead pipes of the drinking-water pipe system engendered the contamination. At present further internal neurological and psychological examinations are being performed.
