Although there is a report of a negative result in an inhalation mouse bone marrow micronucleus test (NTP DE (access on June 2009), the exposure conditions for the substance are unknown. It cannot be excluded that the substance can exert genotoxic effects in consideration of a genotoxic potential reported with cadmium ion (water soluble cadmium compounds) (EU RAR 75 (2007). Based on the information, the substance was classified into Category 2. As relevant information, from in vitro mutagenicity tests, there are reports of negative Ames tests (IARC 58 (1993), NTP TOX39 (1995), NTP DB (access on June 2009)). There is a report that humans who had been exposed to cadmium (itai-itai patients) showed chromosomal aberrations in peripheral blood lymphocytes (IARC 58 (1993)). In addition, the substance is classified into R68 in EU classification.

In an inhalation developmental toxicity test in mice, a lower pregnancy rate, increased total number of resorptions per litter and an increase in the incidence of reduced sternebral ossification were observed at doses that were parental general toxic (NTP TOX39 (1995)). Based on the data, the substance was classified into Category 2. As relevant information, lower offspring body weight was observed at dose levels that were not parental general toxic.
8 Specific target organ toxicity - Single exposure Category 1 (respiratory system, digestive system) Danger H370: Causes damage to organs (respiratory system, digestive system) P307+P311: IF exposed: Call a POISON CENTER or doctor/physician.

For humans, a case of pneumonitis was reported for a man exposed to the substance for 3 days (ACGIH (7th, 2001)). Additionally, there is a report that 9 years after a single exposure to the substance, a worker continued to show signs of progressive pulmonary fibrosis and had no improvement in respiratory function (ATSDR (2008)). In dust inhalation tests with rats, exposures to 1 - 10 mg/m3 resulted in interstitial pneumonitis, alveolar epithelial hyperplasia, alveolitis with hemorrhage, and hyperplasia of fibroblasts (ATSDR (2008)). In addition, as acute effects of cadmium compounds to humans, "chemical pneumonitis and oedema after inhalation exposure, and rapid onset with severe nausea, vomiting, and abdominal pain after ingestion" are characteristic symptoms (EHC 134 (1992)). Based on the data, the substance was classified into Category 1 (respiratory system, alimentary system).
9 Specific target organ toxicity - Repeated exposure Category 1 (respiratory system, kidney, bone, cardiovascular system) Danger H372: Cause damage to organs through prolonged or repeated exposure (respiratory system, kidney, bone, cardiovascular system) P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.

There are reports of "in humans, long term inhalation of cadmium oxide fumes or dusts leads to reduced lung function and emphysema" and "a substantial body of information is available indicating that the lung, kidney and bone are the main target organs upon repeated exposure to cadmium oxide/cadmium metal in occupational settings (mainly by inhalation)" (SIDS (2004)). Additionally, it was reported that hypertension and abnormalities in the electrocardiogram were observed in workers at a battery factory exposed to cadmium oxide dust (EHC 134 (1992)). Based on the data, the substance was classified into Category 1 (respiratory system, kidney, bone, cardiovascular system). As relevant information, as chronic effects of cadmium compounds to humans, "renal dysfunction such as glomerular proteinuria, hypercalciuria, disturbances in rate of calcium to phosphate, hypophosphataemia, formation of renal stones, osteomalacia and osteoporosis" are characteristic (EHC 134 (1992)).
10 Aspiration hazard Classification not possible - - - - No data available.
