Abstract

Studies were conducted to determine whether or not elements whose valence shell of electrons was similar to that of selenium would reverse the toxicity of selenium to chicks. The elements studied were arsenic, tellurium, tin, and lead. Each of these elements, when added to the diet of chicks, reversed the toxicity of 25 ppm selenium as measured by weight gain. In spite of the protection afforded by these elements, there was no decrease in liver concentration of selenium except with levels of arsenic higher than that needed for reversal of toxicity.

摘要

开展了多项研究,以确定其价电子层与硒相似的元素是否会逆转硒对雏鸡的毒性。所研究的元素有砷、碲、锡和铅。当将这些元素中的每一种添加到雏鸡的日粮中时,通过体重增加来衡量,都能逆转25 ppm硒的毒性。尽管这些元素提供了保护作用,但除了高于逆转毒性所需水平的砷之外,肝脏中的硒浓度并未降低。
