Further information

There are several human case reports of neurological effects resulting from high exposure to methyl ethyl ketone in combination with other solvents. Animal studies have confirmed synergism between methyl ethyl ketone and ethyl n-butyl ketone, methyl n-butyl ketone, n-hexane, carbon tetrachloride, 2,5-hexanedione and chloroform. Principal target organs involved in toxicological interactions are the nervous system and liver, although the lung has also been implicated.
