Consider a lagoon with three environmental compartments: air, water, and fish. Suppose $200$ kg of dichloromethane $($CH$,$Cl$)$ is accidentally spilled. The $200$ ke of air basin contains $10$ billion meters cubic of air, $5$ billion liters of water and $5\mathrm{.}0$ m$3$ of fish. What is the environmental partitioning of dichloromethane between the three compartments in mole and the concentration in mol$/$m$\text{'}?$ The bioconcentration factor of the contaminant is $23$ L$/$kg according to the EPA and the average body density of fish is $1\mathrm{.}1$ g$/$cm$\text{'}.$ The vapor pressure is $0\mathrm{.}46$ atm at $25\backslash$deg C$,$ which is the average ambient temperature, and the Henry constant is $3\mathrm{.}25$X$10\text{'}$ atm m$\text{'}/$mol$.$
