Overview assessment production and control of environmental pollutants from industrial factories located in the Miyaneh

Environmental assessment can be defined as assessment which deals with a spatial scale that contains multiple habitats with multiple sources of many stressors affecting multiple endpoints [1]. In recent years, owing to the increasing growth of world population, there has been a dramatic improvement in technology. Therefore, environmental pollution has been increased [2]. In this paper, many industries qualified environmental pollutants located in the Miyaneh and there suburbs have been studied. The aim of this work is achieving to the amount of industrial wastewaters and air pollutants production as well as control and reduces them with the usual methods such as wastewater treatment plant and gas purifier filters installed in the chimneys of factories. Results showed that the most industries use conventional methods instead of advanced standard processes to control and reduce pollution. In some of them, wastewaters contain high COD discharged to environment without treatment process. Industries such as food industry and Animal and poultry slaughters have had wastewaters. Gypsum factories had the problem of not using the purifier filters for quality control of air pollutant gas.
