[Rationale for the Classification]
Because in vivo data on this substance itself available for the classification were not obtained, information on the whole cadmium compounds (as cadmium ion, Cd2+) was used for evaluation.
From (1), (2), positive reports in germ cells and somatic cells were obtained on water-soluble cadmium chloride. There is no information on water solubility of this substance, but because this substance is thought to be very soluble in water like the anhydrate, this substance was classified in Category 1B as the anhydrate was. The category was revised by considering knowledge on the whole cadmium compounds and water solubility of this substance.

[Evidence Data]
(1) It is reported that after administration of cadmium (mainly cadmium chloride), chromosomal aberrations in mouse spermatocytes and hamster oocytes and altered gene expression in mouse spermatid occurred (ATSDR (2012), IARC 58 (1993)).
(2) It is reported that as the result of administrating cadmium chloride to mice, dose-dependent increases in the incidences of micronuclei, sister chromatid exchanges, and chromosomal aberrations were observed in the peripheral blood. Moreover, it is reported that increased single strand breaks in the DNA were observed in rats after administrating cadmium chloride (EU-RAR (2007), DFGOT Vol. 22 (2006), NICNAS IMAP (Accessed Dec. 2018)).

[Reference Data, etc.]
(3) It is reported that increases in the incidences of micronuclei and sister chromatid exchanges in peripheral lymphocytes were shown in workers occupationally exposed to cadmium (compound not specified) and that human lymphocytes from people inhabiting cadmium-polluted areas of China were found to have increased micronuclei rates and a higher frequency of chromosomal aberrations and severe aberration types. However, conflicting knowledge is also reported (ATSDR (2012)).
(4) As for in vivo, a dominant lethal test by administrating cadmium (mainly cadmium chloride) was negative (ATSDR (2012), IARC 58 (1993), DFGOT Vol. 22 (2006)).
(5) As for in vitro, it is reported that a bacterial reverse mutation test, a chromosomal aberration test and a sister chromatid exchange test in cultured mammalian cells (CHO) were positive (NICNAS IMAP (Accessed Jan. 2019)).
(6) There is no information on water solubility of this substance, but that of the anhydrate is 1,560 g/L (HSDB (2012)).
(7) The anhydrate of this substance was classified in Muta. 1B in EU CLP.
