$4\mathrm{.}2$C$.$ Evaporation of Low$-$Solubility Contaminants from Water Surfaces

Evaporation parameters for several chemicals appear in Table $4\mathrm{.}2-1.$

Calculate the vaporization half$-$life and mean residence time for $n-$octane,

benzene, DDT$,$ and Aroclor $1242.$ Assume a water depth of $1m$ free of

suspended solids.

Repeat the calculation for Aroclor $1242$ using Hickory Hills Pond Sediment

$($Table $2\mathrm{.}1-6)$ with suspended solid concentrations of $1,10,100,1000,$ and

$10,000m\frac{g}{L}.$
