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 contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

Effects of long-term or repeated exposure
The substance may have effects on the liver. This may result in liver impairment. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


Occupational exposure limits
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish, milk, plants and mammals. The substance may cause long-term effects in the aquatic environment. This substance may be hazardous to the environment. Special attention should be given to its persistence in soil and its adsorption into sediments. 

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