Simultaneous multielement analitical methods on heavy metals in urine and cautionary points for analysis

Abstract

The methods of simultaneous analysis of heavy metals in urine using simultaneous multielement atomic absorption spectrophotometry were examined. Seven elements, Co, Cr, Cu, Mn, Ni, Pb, Cd, important as environmental chemical hazards were examined concerning, analytical method, term and cautionary points for human urine analyses. Analytical method of creatinine in urine was improved with no reexaminations. Standard added method is superior to the working curve method for human urine analyses.
Highly precise urine analysis is possible by the standard added method without consideration for deterioration of source of light.
