Potential Toxic Effects Of Chromium Chromite Mining And

Dec 14, 2021

Potential reproductive effects of chromium in humans have not been adequately investigated. Data indicate that Cr(VI) compounds are teratogenic in animals. Cr(VI) compounds induced DNA damage, gene mutation, sister chromatid exchange, chromosomal aberrations in a number of targets, including animal cells in vivo and animal and human cells in vitro
