بررسی غلظت عناصر سنگین سرب و روی در گرد و غبار در استان کرمانشاه

This research was conducted in three places of Kermanshah and Sarpol Zahab using the information layer of accumulation areas, data related to meteorological stations in the period 2000 to 2017, adjacent to residential centers, with an emphasis on the wind factor and field operations. To carry out field operations and collect the settled dust particles, glass traps with dimensions of 1 x 1 meter were used with three repetitions in the cities of Kermanshah and Sarpol Zahab. Collection of dust particles for each storm event was collected cumulatively on each transect from the beginning to the end of dust persistence. In order to analyze the particle size of the sediment samples, the laser method was used, and the ICP-MS test method was used to determine the geochemistry of the sediments.The results of the geochemical analysis of the sediments using the ICP-MS method showed that the average concentration of elements in the samples included Zn (269.6 ppm) and Pb (70.4 ppm). that this concentration is more than the standard concentration of zinc (64.3 ppm) and lead (less than 20 ppm). Based on the results and available evidence of the most important sources of dust storms studied in the north of the Arabian parts of Syria, southern Iraq and even the western parts of Khuzestan province, which have significant amounts of carcinogenic heavy metals with a concentration far exceeding the permissible limit for human health and Therefore, the control of dust centers requires the adoption of management plans at the internal, regional.
