The Geochemical Distribution and Assessment of Heavy metals Pollutions in Soil Sediment of Chamchamal City-Sulaimanya Governorate / NortherEastern Iraq.

摘要

The current study aims at the geochemical distribution of heavy elements in soil sediments.It assesses environmental pollution using pollution index and potential health hazards in the city of Chamchamal northeastern Iraq. Twenty-one samples of soil sediments were collected in the area of residential, commercial and industrial areas in mid-July 2017. Heavy metals (As, Cu, Cr, Cd, Co, Fe, Mn, Mo, Ni, Pb, Zn) were analyzed using ICP-MS. The results showed that arsenic, chromium, cadmium, cobalt, manganese and nickel were the highest concentration in residential areas.While molybdenum and lead were higher in commercial areas, wheras copper, iron and zinc recorded the highest concentration in industrial areas. The results of pollution indicators (Igeo) showed that the arsenic was the (Moderately contaminated), The values of the (EF) index of the arsenic are (Significant enrichment), the cadmium and nickel were (moderate enrichment), and the values of Cdeg showed that some of samples are (Contamination Moderate) wheras the rest of the sites are considered (Contaminated) by heavy metals studied. The PRI values indicated that some models were of (Riskable) and others (Very High Risk).
