Abstract
The purpose of this investigation was to find out whether chronic exposition to lead increases the blood pressure. A group of 46 workers in a storage battery factory has been examined. The concentration of lead in air has been previously estimated (Arh. hig. rada, 2 /1951/ 19) to vary from 0-2 mg/m3, most frequently from 0.2--0.4 mg/m3. ln the present investigation the exposition to lead has been measured by the concentration of lead in blood, the coproporphyrine level in urine and the number of stippled cells. The control group consisted of 46 metal workers with no known previous exposition to lead. The same examination have been performed on this group of workers except the determination of lead in blood. Both groups were examined under the same conditions; the experimental and the control group were balanced with respect to age. The measurements of the systolic blood pressure gave an arithmetic mean of 106 mm Hg in the experimental group (exposed to lead) and 116 in the control group. Thus the hypothesis that the chronic exposition to lead increases the blood pressure cannot be accepted on the basis of this evidence.
