Investigation of 74 adult males employed in the lead industry revealed that symptoms of lead poisoning were common when the erythrocyte lead level exceeded 160 ug/100ml. Abdominal pain was the most frequent symptom followed by headache and muscle weakness. The only sign encountered was the gingival ""lead line"" which was a reliable sign of lead poisoning. Elevation of urinary coproporphyrins and the A blood basophilic stipple cell count were too erratic to be of value as screening tests for lead poisoning. Erythrocyte lead levels should be determined regularly to detect excessive retention of lead in subjects industrially exposed to lead.
