Contaminants resulting from industries include dust, carbon compounds, sulfur and nitrogen. The purpose of this study was to evaluate the output of pollutants from cement plants in soil samples and leaf tree species. Methods: This study descriptive-analytic was designed tree species, plants and soil around the plant. Samples from four different stations within 500 meters of factory and 21 packages (each package contains three examples of the sample) were sent for laboratory tasks. Information of sampling stations in the soil, the plants and factories of qualitative and quantitative tests on samples of soil pollutants output of factories, plant species and trees daily and using written lists were collected. After the sampling, the samples were measured using standard methods and analyzed using statistical software. Results: Distribution of the total amount of metals in oak and black plants and reed Talo is normal and can be used for parametric tests. Also, there is no significant relationship statistically among the total amount of metals in plants such as oak trees, reed and Siah Talo. Conclusions: According to the findings of this study, we can conclude that dust subsides the leaves of three species of oak and black Talo and reed which contain considerable concentrations of metals such as silver, barium, bismuth, cesium, chromium, cobalt, cadmium and arsenic.展开更多
