Chromium (VI) mu bikinisho

Chromium nicyuma gifite leta nyinshi za valence, izisanzwe muri zo ni Cr (III) na Cr (VI).Muri byo, uburozi bwa Cr (VI) burenze inshuro 100 kurenza ubwa Cr (III).Nuburozi cyane kubantu, inyamaswa n’ibinyabuzima byo mu mazi.Yashyizwe ku rutonde rwa kanseri y'ibanze n'ikigo mpuzamahanga gishinzwe ubushakashatsi kuri kanseri (IARC).
