| Abstract |
A study to evaluate the sources of interference in the determination of the concentrations of metals in human hair. Using atomic absorption spectrophotometry and a standard reference hair sample, the authors established that the determination of concentrations of copper, zinc, lead and cadmium is free of interference when nitric acid is used as the sole digesting agent. They also demonstrated that chemical ionisation, light scattering and molecular absorption interferences are absent when commercially available equipment is used. |
