Mercury is classified into "Skin Sensitizing Substance" by the ad hoc committee of the Japanese Society of Occupational Allergy, and "Skin Sensitizing Substance: Group 1"* by the Japan Society for Occupational Health. These classifications, though not specifying mercury oxide, seem to include mercury compounds. Mercury oxide, which is a mercury compound, should thus cause skin sensitization. * There is a provision to the effect that "the category refers to the substance concerned and its compounds, but does not identify all substances causing respiratory/skin sensitization.
5 Germ cell mutagenicity Classification not possible - - - - No data available As for the mutagenicity/genotoxicity of inorganic mercury, refer to "ID285, Mercury Chloride (II), CAS: 7487-94-7."
6 Carcinogenicity Not classified - - - - Based on the fact that the substance is classified as Category A4 (as metal mercury and inorganic mercury compounds) by ACGIH (2001) and Group 3 (as metal mercury and inorganic mercury compounds) by IARC (1993).
7 Reproductive toxicity Classification not possible - - - - Insufficient data available As for the reproductive toxicity of inorganic mercury, refer to "ID285, Mercury Chloride (II), CAS: 7487-94-7."
8 Specific target organ toxicity - Single exposure Classification not possible - - - - No data available Note: According to CICAD 50 (2003), "renal failure, cardiovascular collapse and severe digestive organ damage are considered to be the causes of death following oral exposure to inorganic mercury. Most common findings among these are gastrointestinal tract lesion and renal failure. Exposure to inorganic mercury appears to induce nephrotic syndrome in humans."
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available Note: According to CICAD 50 (2003), "renal failure, cardiovascular collapse and severe digestive organ damage are considered to be the causes of death following oral exposure to inorganic mercury. Most common findings among these are gastrointestinal tract lesion and renal failure. Exposure to inorganic mercury appears to induce nephrotic syndrome in humans."
10 Aspiration hazard Classification not possible - - - - No data available
