For this purpose, samples were taken from 9 points, and heavy metals such as iron, manganese, cadmium, copper, zinc, and lead has been analyzed to calculate the indicators of Geoaccumulation Index and pollution factors for these heavy metals. The background element concentration should be calculated for each element to calculate these factors. 59 samples for each element were used in the pristine areas of Urmia Plain by atomic absorption method. The presented research results show that the soil of the region is contaminated with heavy metals, so the amount of contamination for heavy metals manganese and cadmium is meager, and for the heavy metals iron and copper, they are in the middle range and for the heavy metals zinc and lead, they are in the high range. The pollution concentration around the town of expansion phase and phase 2 is more than the town of phase 1, which seems to be the cause of the food industry activity in the town of phase 1 and the activity of electronics, paint and metal industries in the expansion phase and phase 2. It seems that the high amounts of lead and zinc heavy metals in the soils around the industrial towns of Urmia are due to the activities of production units such as electronic industry, ceramics industry, metal industry, paint industry and battery production. The aforementioned industries dump their industrial waste water into the surroundings of the towns and cause soil pollution. Figure 7 shows the discharge of industrial wastewater from the expansion phase town to surrounding area. It seems that the creation of a wastewater treatment plant for polluting units and increasing the capacity of the existing treatment plant in the industrial town is important in reducing pollution.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen La contaminación del suelo superficial de las tres ciudades industriales de Urmia, a 9 km al noreste de esta ciudad, es el tema de este artículo. Para ello, se tomaron muestras en 9 puntos y se analizaron metales pesados como hierro, manganeso, cadmio, cobre, zinc y plomo para calcular los indicadores del índice de geoacumulación y los factores de contaminación de estos metales pesados. Para calcular estos factores, debe calcularse la concentración de fondo de cada elemento. Se utilizaron 59 muestras para cada elemento en las zonas prístinas de la llanura de Urmia mediante el método de absorción atómica. Los resultados de la investigación presentada muestran que el suelo de la región está contaminado con metales pesados, por lo que la cantidad de contaminación para los metales pesados manganeso y cadmio es exigua, y para los metales pesados hierro y cobre, están en el rango medio y para los metales pesados zinc y plomo, están en el rango alto. La concentración de contaminación en los alrededores de la ciudad de la fase de expansión y de la fase 2 es mayor que en la ciudad de la fase 1, lo que parece deberse a la actividad de la industria alimentaria en la ciudad de la fase 1 y a la actividad de las industrias electrónica, de pinturas y metalúrgica en la fase de expansión y en la fase 2. Parece que las elevadas cantidades de metales pesados de plomo y zinc en los suelos de los alrededores de las ciudades industriales de Urmia se deben a las actividades de unidades de producción como la industria electrónica, la industria cerámica, la industria metalúrgica, la industria de pinturas y la producción de baterías. Las industrias mencionadas vierten sus aguas residuales industriales en los alrededores de las ciudades y provocan la contaminación del suelo. La figura 7 muestra el vertido de aguas residuales industriales de la ciudad en fase de expansión a los alrededores. Parece que la creación de una planta de tratamiento de aguas residuales para las unidades contaminantes y el aumento de la capacidad de la planta de tratamiento existente en la ciudad industrial son importantes para reducir la contaminación.]]></p></abstract>
