Write a theoretical introduction regarding this problem, the introduction should take about $1$ page, I do not want you to solve the problem, but write an introduction regarding its subject The chemical $1-$chloro$-2-$nitrobenzene is an intermediate in production

dyes. It is very resistant to hydrolysis and biodegradation, so it can be assumed that it is

persistent in the environment. At $20$C its solubility in water is $440$

mg$/$l$,$ the vapor pressure is $4\backslash$times $10-5$ bar and the KOW is $224.$ Determine its concentration in each

area if $100$ kg of this substance is released into the model environment

consisting of $6\backslash$times $109$ m$3$ of air, $7\backslash$times $106$ m$3$ of water, $4\mathrm{.}5\backslash$times $104$ m$3$ of soil and $2\mathrm{.}1\backslash$times $104$ m$3$

sediment.

It can be assumed that the soil contains $2\%$ by mass. organic matter and has a density of $1500$ kg$/$m$3,$

while the sediment contains $5\%$ by mass. organic matter and has a density of $1300$ kg$/$m$3.$
