ʻO Chromium kahi metala me nā mokuʻāina valence he nui, ʻo ka mea maʻamau o ia mau mea ʻo Cr (III) a me Cr (VI).Ma waena o lākou, ʻoi aku ka ʻona o Cr (VI) ma mua o 100 mau manawa kiʻekiʻe ma mua o ka Cr (III).He mea ʻawaʻawa loa ia i nā kānaka, nā holoholona a me nā mea ola wai.Ua helu ʻia ma ke ʻano he carcinogen mua e ka International Agency for Research on Cancer (IARC).
Ua hoʻohana ʻia ka CIC-D120 ion chromatograph a me ka inductively coupled plasma mass spectrometry (ICP-MS) no ka nānā ʻana i ka migration chromium (VI) i nā mea pāʻani me ka wikiwiki kiʻekiʻe a me ka ʻike kiʻekiʻe, i hoʻokō i nā koi o ka European Union Toy Safety Standards EN 71-3 2013 + A3 2018 a me RoHS no ka ʻike ʻana i ka chromium (VI) (e like me IEC 62321). Wahi a (EU) 2018/725, mea 13 o ka Māhele III o ka European Union Toy Safety Directive 2009/48 / EC Annex II, ka Hoʻoponopono ʻia ka palena neʻe o chromium (VI) penei:
