Today distribution method and atmospheric contamination emission muddling is vulnerable in city region because industrial units grow in underdeveloped countries and contaminated produced by this units. Atmospheric contaminated distribution muddling is method for estimate concentration level and contaminated concentration in different interval relative to emission source. This practice is restricted to step after events occurring without proper administering these programs and we have more timely and monetary cost. In this paper investigate concentration distribution study from 2 dimensional and non-permanent states in land surface. If there is barrier in front of chimney, there is more contaminated gas distribution after chimney and maximum contaminated density is less in earth. When there are 3 chimney, There is no effect on contaminated density maximum distance. But in situation there is barrier in front of chimney, this distance is 1000 meter next to chimney. Earth atmosphere attack all kinds of contaminated due to industrial grow development and citizen grow. Modeling and investigating this contaminated distribution in environment surface uneven and kind of cover has basic role in contaminating distribution method because inhalator this contaminated in soil and ware have non-compensate damage to environment. One of the major concerns of industries is their effects on environment and sustainable development trend.
