Application of radiochemical neutron activation and flame atomic absorption spectrometry for the determination of manganese in blood
- 29 Downloads
Methods for the determination of manganese in blood by radiochemical neutron activation and flame atomic absorption spectrometry have been developed. Both methods are applicable for routine use in preventive medical checkups of workers who are exposed to manganese. The accuracy and precision of both methods have been tested by analyzing standard freeze-dried blood (A-13) prepared by the International Atomic Energy Agency. The blood manganese contents of 109 non-exposed people living in Bangkok have been analyzed. The concentrations are normally distributed with a mean value of 1.47 μg/100 cm3 and a standard deviation of 0.50 μg/100 cm3.
