| 520 | $aCobalt and nickel, matrices of hard metal, have been shown to be respiratory sensitizers. Airborne dust at hard metal-griding worksites in a factory with a work-force of about 180 grinders was analysed for cobalt and nickel. The electron-microscopic X-ray microanalysis of airborne dust particles demonstrated that they had the same metallic components as hard metal products. Andersen sampling revealed that 66% of total dust was respirable (<7 microm). Consecutive personal sampling for individuals indicated log-normally distributed concentrations of total dust and cobalt. Of the workers surveyed, 12% (16 out of 133) were exposed to cobalt at more than 50 microm exp. (-3), while 1.5% (two out of 133) were exposed to nickel concentrations of more then 50 microm exp. (-3). A correlation between cobalt exposure concentrations and nickel concentrations for individuals was significant and positive | ||
