1 From the Division of Biochemistry of the Laboratories of Philadelphia General Hospital, Philadelphia, Pa.
The excretion of lead in urine and feces of 9 patients after long-continued exposure to lead was determined before and during the administration of sodium citrate. Appreciable increases in urinary, fecal and total excretion in 8 of the 9 cases occurred during citrate therapy. The mean increase in total excretion of lead during citrate therapy for all 9 cases is statistically significant.
