Abstract

Thirty-five soil samples were collected from the Tanning FactoryIndustrial District within Baghdad city to investigate the soil pollution occurthrough four directions of the tanning plant. The soil samples exhibited highconcentrations of Cr than the reported values of worldwide mean of unpollutedsoils. The geoaccumulation index showed that the soil samples were moderatelypolluted by Cr at the north of the factory while the soil sample showed extremelypolluted at the south and east of the factory. Moreover, the soil samplescollected from west of the factory were strongly polluted. The result of thecalculated enrichment factor (64.52-1075.22) showed to extremely highenriched and suggesting a significant role of anthropogenic pollution because ofvarious industrial activities by the Tanning Factory

Abstract

Water Quality of Mahrut River, passing through Muqdadiyah, a city in Diyala, Iraq, was evaluated for irrigation using the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI). Water samples were collected from six sites during two seasons, summer and winter in 2010-2011. Index scores were determined for fifteen constituents (pH, EC, HCO3, Cl, Sodium Absorption Ratio (SAR), Soluble Sodium Percentage (SSP), Residual Sodium Carbonate (RSC), Cd, Cr, Cu, Fe, Pb, Mn, Ni and Zn). The results of the calculated CCME WQI indicated that water quality of Mahrut River was marginal condition for irrigation in the 1st site while it was poor condition in the other sites. It is suggested that monitoring of the river is necessary for proper management to solve pollution problems in the river system.

تم تقييم نوعية مياه نهر مهروت الذي يمر في مدينة المقدادية في محافظة ديالى/ العراق، لاغراض الري باستخدام دليل نوعية المياه الكندي (CCME WQI). جمعت العينات المائية من ستة مواقع خلال موسمي الصيف والشتاء (2010-2011). تم تحديد نتائج مؤشر الدليل لخمسة عشر متغير (درجة الاس الهيدروجيني، التوصيلية الكهربائية، الكاربونات، الكلوريد، نسبة امتزاز الصوديوم، النسبة المؤية للصوديوم الذائب، كاربونات الصوديوم المتبقية، الكادميوم، الكروم، النحاس، الحديد، الرصاص، المنغنيز، النيكل والخارصين). بينت نتائج حساب دليل نوعية المياه ان مياه نهر مهروت هي من النوعية الهامشية (marginal) لاغراض الري في الموقع الاول الذي يقع شمال المدينة في حين انها مياه فقيرة (poor) في المواقع الاخرى. ان مراقبة نوعية مباه النهر تعد ضرورية للادارة المائية السليمةلحل مشاكل التلوث ضمن منظومة النهر.

Abstract

Analysis of eight heavy metal concentrations (Cd, Cr, Cu, Fe, Mn,Ni, Pb and Zn) of 14 drilling mud samples collected from oil well at differentdepths which is located in AZ Zubair oil field-Basra was done in this study .The samples were measured using atomic absorption spectrophotometry.Obtained results indicated that the heavy metal concentrations range from thelowest value of 1.66mg/kg for Cd to the highest value of 1235.86mg/kg forFe. The abundance trend for the heavy metals concentration was in thedescending order of Fe, Mn, Ni, Cu, Cr, Zn, Pb, and Cd. Four parameters:Enrichment Factor (EF), Contamination Factor (CF), Geo-accumulationIndex (Igeo) and Pollution Load Index (PLI) were assessed in order toevaluate the degree of contamination.
