Abstract :
Among environmental pollutants, heavy metals due to the heavy metals are not biodegradable and have physiological effects on living organisms at low concentrations is of particular importance. These elements due to low mobility in the soil gradually accumulate. The accumulation of these elements in the soil would eventually enter the food chain and are threatening human health and other organisms. This study aimed to determine the chromium in the Alhagi Camelorum plant as a supplier of small ruminant forage and soil bed in transit road of Tabriz - Sufian. Soil and plant samples in four directions at intervals of road edges, 15, 30, 60 and 120 m from the roadsides was prepared. To determine the amount of chromium, atomic absorption method was used. The results showed that the highest concentration of chromium in soil is 30 km of road Tabriz -Sufian and near of Sufian cement factory with 51/29 mg/ kg in the left margin of the road and the highest concentration of 54.3 mg/ kg in the Alhagi Camelorum. With increasing distance from the Sufian cement factory concentration of chromium were decreased in soil and plant. The results showed that the concentration of chromium in soil and Alhagi Camelorum plant in the course of study at a relatively high road edges and usually with increasing distance from the roadside concentrations of metals has been reduced. According to the local winds, heavy metal accumulation in the left side of the road is high, the 30 -kilometer road in Tabriz - Sufian, concentration of chromium metal in very high. Due to the contamination of plant and affected products of grazing animals such as milk and meat, consequently, the entry of animal products into the human food chain can be adverse effects on the integrity of animals and humans.
