Chromium ndi chitsulo chokhala ndi maiko ambiri a valence, omwe amadziwika kwambiri ndi Cr (III) ndi Cr (VI).Pakati pawo, kawopsedwe ka Cr (VI) ndi woposa nthawi 100 kuposa Cr (III).Ndiwowopsa kwambiri kwa anthu, nyama ndi zamoyo zam'madzi.Amalembedwa ngati carcinogen yoyamba ndi International Agency for Research on Cancer (IARC).
CIC-D120 ion chromatograph ndi inductively plasma mass spectrometry (ICP-MS) idagwiritsidwa ntchito kusanthula migration chromium (VI) muzoseweretsa zothamanga kwambiri komanso zowoneka bwino, zomwe zimakwaniritsa zofunikira zachitetezo chachitetezo cha European Union TS EN 71-3 2013+A3 2018 ndi RoHS pozindikira chromium (VI) (malinga ndi IEC 62321). Molingana ndi (EU) 2018/725, item 13 of Part III of European Union Toy Safety Directive 2009/48/EC Annex II, the malire a kusamuka kwa chromium (VI) amasinthidwa motere:
