In this research, in order to assess and risk management of North Cement Factory, emission rate of air pollutants surrounding the mills no1, no2, no3, exhaust from the chimney of new product mill, electro filter, exhaust of klin no2, consisting CO. NO, NO2 and particles were measured. Air pollutants by Testo350 apparatus were measured. The calculation of this research indicated that the concentration of some air pollutants in the North Cement Factory is higher than the viable standards. The amount of NOx is acceptable whereas the amount of CO, is twice and the PM particulates on average is 6 times higher than the authorized amount. The rate of coliforms in waste was 40 times more than the permitted amount. Not only do these pollutants dissipate the Cement but they also cause irrevocable damages in the environment. According to implemented Classification,30% of aspects were low-risk level, 37.5% were Mid-risk level, 25% were high-risk level and 7.5% were extremely high-risk level. Eventually to decrease the efficiency of filteration equipments as well as more efficient management of the factory, effective management measures were presented.
