In a lead accumulator producing factory the health risk of workers has been studied for more than 30 years by means of measuring the lead concentration at the working places for many years and by carrying out several exposure tests on the 22 workmen. At most workshop places the maximum allowable concentration was considerably exceeded. In many workmen the concentration of lead in the blood and the delta aminolevulinic acid in the urine were increased above the control values. Since 1955 six occupational diseases have been diagnosed which demonstrates the high health risk.
