I-Chromium yintsimbi eneendawo ezininzi ze-valence, ezona ziqhelekileyo ziyi-Cr (III) kunye ne-Cr (VI).Phakathi kwabo, i-toxicity ye-Cr (VI) ingaphezulu kwamaxesha e-100 ngaphezu kwe-Cr (III).Iyityhefu kakhulu ebantwini, kwizilwanyana nakwizinto eziphila emanzini.Ibhalwe njenge-carcinogen ephambili yi-Arhente yamazwe ngamazwe yoPhando lweCancer (IARC).
I-CIC-D120 ion chromatograph kunye ne-inductively zidityaniswe ne-plasma mass spectrometry (ICP-MS) zisetyenziselwe ukuhlalutya i-chromium yokufuduka (VI) kwizinto zokudlala ezinesantya esiphezulu kunye novakalelo oluphezulu, oluye lwahlangabezana neemfuno zemigangatho yokhuseleko lwethoyi ye-European Union EN 71-3. I-2013 + A3 2018 kunye ne-RoHS yokufunyanwa kwe-chromium (VI) (ngokwe-IEC 62321) .Ngoko (EU) 2018/725, inqaku le-13 leCandelo III le-European Union Toy Safety Directive 2009/48/EC Annex II, i umda wokufuduka kwechromium (VI) uhlengahlengiswa ngolu hlobo lulandelayo:
