Methyl ethyl ketone is not expected to be retarded by adsorption
to soils rich in organic material [estimated Koc = 4.5-50 (U.S.
EPA 1989)]; therefore, it is expected to be mobile in soil and,
subject to leaching from landfills. The relatively high vapor
pressure [98.0 mm Hg @ 25øC (U.S. EPA 1985)] and estimated
Henry's Law constant (4.16-6.11 x 10-5 atm m3/mol @ 25øC) indicate
that it can volatilize from moist and dry soil (HSDB 1994). It
does not adsorb significantly to suspended solids, and will
volatilize to the atmosphere from surface waters (HSDB 1994;
U.S. EPA 1985).
