It is known that environment pollutions are health-endangering for human and their effects include blood enzyme changes, anemia, hyperactivity, and neurological disorders. A multitude of natural antioxidants have already been isolated from different kinds of plant materials. Plants contain a diverse group of phenolic compounds including simple phenolics, phenolic acids, anthocyanins, hydroxycinnamic acid derivatives and flavonoids. Therefore, in this research, the effects of industrial and electromagnetic fields pollutions on phytochemical parameters of Zea mays were determined. So, plants were collected from east of Isfahan area (surrounding industrial areas, with electromagnetic fields areas and non-pollution area), Iran and the contents of phenolic compounds, total flavonoid and antioxidant activity were investigated. So that , for evaluation of antioxidant activity and total phenolic, flavonoid of methanolic extract these plants were used from DPPH (2,2-diphenyl-1-picrylhydrazyl) model system, Folin-Ciocalteu method and aluminum chloride colorimetric method, respectively. The results of this study were analyzed using different statistical tests including ANOVA and LSD. The results indicated that the amount of phenol, flavonoid and antioxidant activity were decreased in all polluted samples but a non-significant decrease was observed in collected Zea mays from electromagnetic pollution areas.
