EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Effects of short-term exposure
 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
The substance may have effects on the blood, bone marrow, central nervous system, peripheral nervous system and kidneys. This may result in anaemia, encephalopathy (for example, convulsions), peripheral nerve disease, abdominal cramps and kidney impairment. Causes toxicity to human reproduction or development. 


Occupational exposure limits
TLV: 0.05 mg/m3, - ppm, as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: carcinogen category: 2; germ cell mutagen group: 3A.
EU-OEL: 0.15 (binding) mg/m3 as TWA 

ENVIRONMENT
Bioaccumulation of this chemical may occur in plants and mammals. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
