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).
CIC-D120 ion chromatograf hamwe na plasma ihujwe na plasma mass spectrometrie (ICP-MS) yakoreshejwe mu gusesengura chromium yimuka (VI) mu bikinisho bifite umuvuduko mwinshi kandi wiyumvamo cyane, byujuje ibisabwa n’ibipimo by’umutekano w’ibikinisho by’ubumwe bw’ibihugu by’Uburayi EN 71-3 2013 + A3 2018 na RoHS kugirango bamenye chromium (VI) (ukurikije IEC 62321) .Kurikije (EU) 2018/725, ingingo ya 13 y'igice cya III cy'Amabwiriza y’umutekano w’ibikinisho by’ubumwe bw’ibihugu by’i Burayi 2009/48 / EC Umugereka wa II, imipaka yimuka ya chromium (VI) ihinduwe kuburyo bukurikira:
