Abstract
Manganese has been determined in the hair of welders and not exposed subjects by means of INNA. Geometric mean for non welders was (1.4×2.1) ppm and for welders (7.0×2.3) ppm. Manganese values correlated well with daily welding time, working place conditions and welding procedure. Correlations were weak for years of exposure and age. While for some clinical data relations to manganese concentrations could be shown by analysis of mean values, there were no significant coefficients of correlation between manganese content in the hair and lung function data.
