Multielement determination of metals in biological specimens of hard metal workers: a study carried out by neutron activation analysis.
Multielemental analysis, using neutron activation, was carried out on the urine, whole blood, pubic hair and toenails of thirty subjects occupationally exposed to hard metal dusts. A high concentration of Co, W and Cr was observed in all samples analysed. The concentrations determined, when subjected to statistical analysis using pattern recognition techniques (e.g. cluster analysis), indicated a positive correlation, at p = 0.001, for the pair (Co, W) in urine and blood, as well as a possible influence of Cr on this pair.
