Abstract

Fifteen metals (lead, cadmium, arsenic, inorganic mercury, organic mercury, iron, manganese, magnesium, chromium, zinc, copper, nickel, cobalt, tin, and aluminum) were determined in the hepatic bile and urine collected simultaneously from three Japanese individuals (2 males, 1 female). The presence of these metals was classified as follows: hepatic biliary concentrations were higher than urinary concentrations (lead, arsenic, and iron); urinary concentrations were higher than hepatic biliary concentrations (cadmium, inorganic mercury, tin, cobalt, magnesium, chromium, copper, zinc, and nickel); hepatic biliary concentrations were almost equal to urinary concentrations (manganese and organic mercury); and relationship between hepatic biliary and urinary concentrations changed occasionally (aluminum). Eight essential metals (iron, manganese, magnesium, zinc, chromium, copper, nickel, and cobalt) were detected at considerable concentrations in hepatic bile. Accounting for the daily flow volume of hepatic bile and the reabsorption of these metals, the supplementation of these metals should occur during treatment of diseases accompanied by loss of hepatic bile.
