    Concentrations of lead and other metals in blood of two and three year-old children living near a secondary smelte (1979)

    Notes: Summary In 108 two-and three-year-old children the concentration of lead, cadmium, manganese, and zinc in blood, of free erythrocyte porphyrin in erythrocytes, and of haemoglobin and haematocrit were measured. The relation with distance of residence to a secondary smelter and with socio-economic class was studied. The ranges were for PbB 45–383 ppb, CdB 0.2–3.5 ppb, ZnB 2.0–9.7 ppm, MnB 2.7–14.1 ppb, FEP 10.5–138.9 μg/100 ml rbc. PbB was influenced independently by the distance to the source of emission and by the socioeconomic class. FEP increased with PbB; Hb and Ht were not affected. The results suggest that the Biological Quality Guide for blood lead as adopted in the European Community may have to be lowered for young children.

    Trace element levels in hair of eight-year-old children (1983)
    Springer
    International archives of occupational and environmental health 53 (1983), S. 127-137 
    Details
    ISSN: 1432-1246
    Keywords: Children ; Ethnic origin ; Hair ; Nutrition ; Trace element
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary A study of trace element levels in hair was performed on 183 eight-year-old schoolchildren living in Bijlmermeer, a suburb of Amsterdam, the Netherlands. Microlevel-elements, such as Au, Co, Ag, Se and Cd, and macrolevel-elements, such as Pb, Cu, Fe and Zn, were analyzed using the NAA and AAS methods. The total group of children was divided into subgroups, according to ethnic origins: Caucasian boys and girls, Hindustani children and a Surinamese rest group. The relation between element levels in hair and nutritional status, anthropometric and haematological variables were studied. Most levels corresponded reasonably with literature data. The iron in hair may be positively related to daily dietary intake of iron.

    On the value of 5-aminolevulinic acid dehydratase activity as predictor for lead in blood (1978)
    Springer
    International archives of occupational and environmental health 41 (1978), S. 147-150 
    Details
    ISSN: 1432-1246
    Keywords: Lead-in-blood ; ALA-D
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary In 222 females lead in blood (PbB) and 5-aminolevulinic acid dehydratase activity (ALA-D) were measured. PbB ranged from 40 to 240 ppb. The measurement error (precision) of PbB-determination was 18ppb. The error in predicting actual lead in blood from ALA-D amounted to 32 ppb. This could be ascribed to biological variation and insufficient specificity of ALA-D for lead in blood. It is concluded that ALA-D as predictor for lead in blood can only be used: 1. for group monitoring 2. as rough measure for lead in blood in individual cases at low levels of lead exposure.
