The influence of seasonal changes in the determination of selenium in liver of various animals by neutron activation analysis and high-resolution spectrometry.
Selenium levels in the liver of animals living in the Umfolozi Game Reserve in Natal and in the Sabi Sand Nature Reserve in the Eastern Transvaal were studied by instrumental neutron activation analysis. The distribution of the selenium content was followed for about 16 months and attempts have been made to explain seasonal fluctuations of the selenium level.
