title: [External quality control measures for blood lead analysis of persons living in a high lead exposure area (author's transl)].
abstract: Analytical laboratories engaged in studies regarding the exposure of larger population groups to lead should--for the sake of better intercomparability of data--subject themselves to internal and external quality control. In this paper an example of external quality control for blood lead, ALA-D and FEP analysis by 3 institutes is given. Evaluation by correlation analysis showed satisfactory results for all 3 parameters studied. Apart from discussing the results, suggestions are made regarding conduction of realistic quality control measures for the 3 lead-dependent biological exposure parameters.
