We investigated the association between the period of exposure and changes in urinary excretion of chromium and nickel among rotating shift workers in a stainless-steel plant. The study participants were composed of two groups: the workers who were occupationally exposed to metals ("exposed group")...
In the current marketing structure, producers are rewarded for pigs with higher amounts of muscle and are discounted for pigs with high fat content. The interest in Cr supplementation during this period in the life of the pig is primarily for its potential impact on muscling, and secondarily ...
