Heavy metals in the site received industrial effluents were investigated to assess the pollution levels, distribution of metal among solid-phase fractions and possible metal sources. The soil samples at different depths of 0–5, 5–25 and 25–50 cm...
Olive mill wastewater (OMW), a liquid by-product of the olive oil industry, represents a severe environmental problem owing to its high pollution load. In this study, successive columns containing different types of natural materials were...
Assessment and heavy metal behaviors of industrial waste water: A case study of Riyadh, Saudi Arabia
This study focuses on the monitoring and chemical analysis of two pathways, unpadded and open drain canal, of the surface industrials effluent on industrial city of Riyadh city, Saudi Arabia. The distribution of the chemical constituents (Major,...
Palygorskite clay mineral is considered one of the dominated clay minerals in clay fraction in many soils and sediments in Arid Regions. This study aimed to determine sorption of mercury by palygorskite clay mineral. Batch sorption and leaching...
Heavy Metals Accumulation of Some Plant Species Grown on Mining Area at Mahad AD`Dahab, Saudi Arabia
Samples from different plants species, which grown around Mahad AD’Dahab Mine, have been selected to study their ability to accumulate these heavy metals. These plant species were: Pergularia tomentosa, Calotropis procera, Acacia tortilis,...
لبدء نشاط تعدين الذهب في أكثر من موقع في المملكة، كانت الحاجة ماسة لدراسة مستويات التلوث في المناطق المتوقع تلوثها. اختير منجم مهد الذهب لأنه الأقدم. وهدفت الدراسة إلى تقويم مدى تلوث الترب المحيطة بمنجم مهد الذهب بالعناصر الثقيلة (As, Be, Cd, Co, Cr...
Plant species Rhazya stricta, which naturally grown around Mahad AD’Dahab Mine, have been selected to study its ability to accumulate heavy metals (Cd, Cu, Pb, Zn). Twenty four samples from roots, stems, and leaves of Rhazya stricta were collected...
The atmospheric concentration of natural greenhouse gases has increased steadily since the industrial revolution. Soil scientists and ecologists recognize the importance of the global carbon cycle and its role in the greenhouse effect. This book...
Because of very limited information of the clay minerals of Southern Jazan region (Saudi Arabia), the mineralogy of the clay fraction has been studied. A total of nineteen soil samples from five sites representing the main landforms in the...
The concentrations of nine heavy metals (Fe, Mn, Zn, Cu, Ni, Cd, Cr, Co, and Pb) in soil samples of Arabian Gulf coast, Saudi Arabia, were investigated. Sediment Quality Guideline (SQGs), SQG-Quotient (SQG-Q), toxicity degree index (TDI), enrichment...
أثبتت الدراسة تلوث ترب مدينة مهد الذهب قرب المنجم وحتى بعد 7 كلم بالعناصر الثقيلة، وقد سجلت المواقع قرب المنجم تركيزاً كبيراً، انخفض مع البعد عنها. حيث أظهر اعتماد بعض المقياس الهولندي والصيني والأسكتلندي تلوث التربة بالعناصر الثقيلة. وبالرغم من...
