Over the years mathematical modellers and atmospheric scientists have laid considerable emphasis on studying and modelling various atmospheric processes so as to estimate pollutant concentration in the atmosphere and adopt several methods for reduction of it. For the purpose in this paper a mathematical model is developed in two patches with variable wind speed, diffusivity and removal term. It is supposed that uniformly distributed sinks are present in second patch. It is also supposed that the ground surface and inversion layer are impermeable. From the above discussion it may be concluded that the presence of sink phase in the second patch in the form of rain droplets, fog droplets or even extremely introduced species (liquid or gas) can be very effective in removing the pollutants from the atmosphere. The analysis also suggests a mechanism by which toxic gases leaked out in the atmosphere due to accidental discharge etc. can be removed by introducing suitable liquid or gaseous phase in the environment using mechanical means. It can also be utilized for studying risk analysis particularly in cases of accidental leakages of pollutants / toxicants in the atmosphere
