On nickel contents in urine and hair in a case of exposure to nickel carbonyl.

In an accidental case of exposure to nickel carbonyl with a few persons weak symptoms of illness were observed. Rapid and simple methods of flameless atomic absorption spectroscopy were applied for the determination of nickel in urinary samples and in sections of bundled hairs. The measurements showed in some cases remarkable increased Ni values well above normal levels. The data obtained will be amply discussed and can be used in part for a rough estimation of the biological half life of inhaled Ni.
