The substance was classified as Category 1 (kidneys) and Category 3 (airway irritant) based on the reports concerning humans in Priority 1 documents that the target organs of the substance in the inorganic mercury compound are the kidneys (DFGOT, vol.15, 2001), and the report of respiratory organ irritant properties in humans in a Priority 2 document (HSFS, 2001). |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (central nervous system, kidney) |
![]() |
Danger | H372: Cause damage to organs through prolonged or repeated exposure (central nervous system, 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 ... |
Since the effect on the central nervous system and the kidney to humans by inorganic mercury compounds is indicatted in Priority 1 document (ACGIH-TLV, 2004;EHC, 118, 1991), and the effect on the kidney was suggested in Priority 2 document (HSFS, 2001), it was classified into Category 1 (central nervous systems,kidney). |
