Mercury is classified into a "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 mercurous chloride, seem to include mercury compounds. Mercurous chloride, 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, refer to "ID285, Mercury Chloride (II), CAS: 7487-94-7." |
6 | Carcinogenicity | Not classified | - | - | - | - | Due to 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 | - | - | - | - | No data available As for the reproductive toxicity, refer to "ID285, Mercury Chloride (II), CAS: 7487-94-7." |
8 | Specific target organ toxicity - Single exposure | Category 1 (kidney), Category 3 (respiratory tract irritation) |
Danger Warning |
H370: Causes damage to organs (kidney) H335: May cause respiratory irritation (respiratory tract irritation) |
P307+P311: IF exposed: Call a POISON CENTER or doctor/physician. 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. P321: Specific treatment (see ... on this label). P405: Store locked up. P501: Dispose of contents/container to ... P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P403+P233: Store in a well-ventilated place. Keep container tightly closed. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P312: Call a POISON CENTER or doctor/physician if you feel unwell. |
Based on the human evidence: "decreased urinary output and edema were observed; renal failure was regarded as a contributing factor of death." (CICAD 50 (2003)) and "eye/skin/respiratory irritation" (ICSC(J) (2000)). 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 | Category 1 (kidney, nervous system, gastrointestinal tract) | Danger | H372: Cause damage to organs through prolonged or repeated exposure (kidney, nervous system, gastrointestinal tract) |
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. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ... |
Based on the human evidence including "abdominal pain, nausea, vomiting, black feces, decreased urinary output and renal failure; irritability, fretfulness, sleeplessness, weakness, photophobia, muscle twitching, hyperactive or hypoactive tendon reflexes, confusion, irregular arm movements, and impaired gait" (CICAD 50 (2003)), "dementia and irritability; reduced brain weight observed at necropsy; decreased cerebellar neurons; mercury granules in the cytoplasm found at the light microscopic level" (ATSDR (1994)). Since gastrointestinal tract effects were observed in the repeated dose toxicity studies using the dermal route of exposure, it is unlikely that these effects represented a direct toxic effect, so the GI tract was included in the target organ list. | |

11 | Hazardous to the aquatic environment (Acute) | Category 1 | Warning | H400: Very toxic to aquatic life |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
It was classified into Category 1 from 48 hours LC50=0.002mg/L of the crustacea (Daphnia magna) (AQUIRE, 2003). | |
11 | Hazardous to the aquatic environment (Long-term) | Category 1 | Warning | H410: Very toxic to aquatic life with long lasting effects |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
Since acute toxicity was Category 1, there was bio-accumulation (BCF=1300 (Existing Chemical Safety Inspections Data)) and it was a metallic compound and the underwater action was unknown, it was classified into Category 1. |
