Title Biomonitoring of manganese in blood, urine and axillary hair following low-dose exposure during the manufacture of dry cell batteries
Bibliographic information Nov. 1999, Vol.72, No.8, p.521-527. Illus. 23 ref.
Abstract A cross-sectional study was carried out on 100 workers from three different workplace areas in a dry cell battery manufacturing plant and on 17 currently nonexposed referents, to examine the relationship between the external exposure to manganese dioxide (MnO2) and the body burden of manganese in blood, urine and hair. Manganese in blood and axillary hair correlated with airborne manganese in group-based calculations but not on an individual level. The manganese concentrations varied between 3.2µg/L and 25.8µg/L in the blood and between 0.4µg/L and 49.6µg/L in hair. Mean values were lower for the nonexposed referents. Manganese differed significantly between the highly exposed workers and both the reference and the low-exposure group. No differences for manganese in urine were observed between workers and referents. Manganese in blood is a specific and suitable parameter for the biomonitoring of MnO2 exposure, although its validity is limited to group-based calculations.
