$4\mathrm{.}1$G$.$ BTX Volatilization Fate in Lower Mississippi River

The fate of benzene, toluene and xylene $($BTX$)$ is of interest to the chemical

industry located along the lower Mississippi River. Assuming Baton Rouge,

Louisiana as the discharge point, compute and graph the fraction of each

volatilized upon reaching the downriver locations represented by Plaquemine,

LaPlace, New Orleans, and Pilot Town. Assume a flow of $500,000f\frac{t^3}{s}$

with benzene mass transfer coefficients of ${?}^1{k}_{A2}^{\text{'}}=4\mathrm{.}1c\frac{m}{h}$ and ${?}^2{k}_{A2}^{\text{'}}=1180$

$c\frac{m}{h}.$ The respective BTX sediment$-$water partition coefficients are $41,90,$ and

$177\frac{L}{k}g.$ Perform calculations for $1\mathrm{.}0$ and $10,000m\frac{g}{L}$ suspended solids

concentration.
