| Comments |
In laboratory studies, animals experienced CNS depression at 2400-2800 ppm and liver and kidney damage after repeated exposures to 1000 ppm. [CHEMINFO] Dichloromethane seldom causes hepatotoxicity "unless exposure is very heavy or agent ingested." [Zimmerman, p. 333] If left on clothes, may cause reddening of skin; [CHRIS] |
