I-Chromium iyinsimbi enezifunda eziningi ze-valence, ezivame kakhulu okuyi-Cr (III) ne-Cr (VI).Phakathi kwazo, ubuthi be-Cr (VI) buphakeme izikhathi ezingaphezu kwe-100 kune-Cr (III).Kunobuthi kakhulu kubantu, ezilwaneni nasezintweni eziphila emanzini.Ifakwe ohlwini njenge-carcinogen eyinhloko yi-International Agency for Research on Cancer (IARC).
I-CIC-D120 ion chromatograph kanye ne-plasma mass spectrometry (ICP-MS) ehlanganisiwe isetshenziswe ukuze kuhlaziywe i-migration chromium (VI) kumathoyizi anesivinini esikhulu nokuzwela okukhulu, ahlangabezana nezidingo zamazinga okuphepha amathoyi we-European Union EN 71-3. 2013+A3 2018 kanye ne-RoHS ukuze kutholwe i-chromium (VI) (ngokwe-IEC 62321). Ngokuvumelana ne-(EU) 2018/725, into 13 yeNgxenye III ye-European Union Toy Safety Directive 2009/48/EC Annex II, umkhawulo wokufuduka we-chromium (VI) ulungiswa kanje:
