Chromium yog cov hlau uas muaj ntau lub xeev, feem ntau yog Cr (III) thiab Cr (VI).Ntawm lawv, qhov toxicity ntawm Cr (VI) yog ntau tshaj 100 npaug ntawm Cr (III).Nws yog tshuaj lom heev rau tib neeg, tsiaj txhu thiab cov kab mob hauv dej.Nws tau teev tseg tias yog thawj cov kab mob carcinogen los ntawm International Agency for Research on Cancer (IARC).
CIC-D120 ion chromatograph thiab inductively coupled plasma mass spectrometry (ICP-MS) tau siv los tshuaj xyuas kev tsiv teb tsaws chromium (VI) hauv cov khoom ua si nrog kev kub ceev thiab siab-rhiab heev, uas ua tau raws li cov cai ntawm European Union cov khoom ua si kev nyab xeeb EN 71-3 2013 + A3 2018 thiab RoHS rau kev kuaj pom ntawm chromium (VI) (raws li IEC 62321).Raws li (EU) 2018/725, yam 13 ntawm Tshooj III ntawm European Union Cov Khoom Ua Si Kev Nyab Xeeb Cov Lus Qhia 2009/48/EC Annex II, Kev txwv kev tsiv teb tsaws ntawm chromium (VI) raug kho raws li hauv qab no:
