25 mg chemical y (log kow = 2.88) is added to a microcosm
(i. e., tank) that contains 1 kg soil, 20 l water. chemical y has
negligible volatility (very low partitioning to air). the soil is
mized with water for several days until equilibrium (between the
chemical concentration on the soil and in the water) is
reached.
if the soil contains 2% organic carbon and it can be assumed
that koc=0.5*kow
what is the concentration of the chemical in the water (mg/l),
and in the soil (mg/kg)?
