水素化物加熱原子化法による生体内微量セレニウム(Se)の定量

抄録

We adopted the rapid semi-automized electorthermal atomisation atomic ab嗣 sorption spectrophotometric procedure for deterrrtination of selenium in biological samples.

It was found that this method is one of the most sensitive techniques available for measuring the trace levels of selenium found in biological materials. Co-existence of high concentration of As, Ni and Cu interferes selenium determination. However, these interference is negligible in the case of determination in biological samples.

By animal experiment, it was clarified that the concentration of selenium in liver and kidney was highly responsive to the dietary selenium level, while it was poorly responsive in brain and testis.
