Refer to potassium dichromate (ID 262, Chemical Abstracts Service:7778-50-9). Moreover, inorganic lead compounds describes that a chromosome aberration is induced to humans in ATSDR (draft, 2005), and is classified into the germ cell mutagenicities 3A (equivalent to GHS Category 1B-2) in MAK/BAT (2005). |

Although there is no data about this product, since about humans, as toxicity of the inorganic lead compounds "symptom that the acute influence of inorganic leads and chronic influence are almost the same is observed" (CERI Hazard Data 2001-9, 2002), in ACGIH-TLV (2005), it effects on the central nervous systems, blood, renal as inorganic leads compound, it was considered as Category 1 (a central nervous system, blood, kidney). In addition, there is description that when orally or percutaneous absorption is carried out as acute toxicities of the hexavalent chromium compound, vomiting, diarrhea, a spasm, a hemorrhagic nephritis, etc. are caused (DFGOT vol.3 (1992), DHP (13th, 2002)). | |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (central nervous system, blood, kidney) | Danger | H372: Cause damage to organs through prolonged or repeated exposure (central nervous system, blood, kidney) |
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 ... |
Although there was no data of this product, as an inorganic lead compound, it effects on central nervous systems, blood, and kidney (ACGIH-TLV (2005) in Priority 1 document). It was classified into Category 1 (central nervous system, blood, kidney). In addition, there is a description of effects on a kidney, nasal septum perforation, ulcers, etc. as chronic toxicity of hexavalent chromium compounds (ACGIH (7th, 2001), IRIS (1998), DHP (13th, 2002)). | |
