Environmental modelling of heavy metals using pollution
Fewer studies have assessed the discharge of industrial, agricultural and municipal wastewaters on heavy metal pollution in the Soils of Bahr El Baqar, Egypt. Thirty-four samples were collected and analyzed for heavy metals, which were assessed using different indices. The summary statistics results indicate that Pb, Cd, Cu, Co, Cr and Ni concentrations in Bahr El Baqar soils are higher than,Naglaa Farag | Alexandria University ,Egypt – Academia.edu,sequence: Fe>Pb>Mn>Ni>Zn>Cr>Cu>Co>Cd. Over than 100% of the samples were lower than the Cr and Zn thresholds effect level (TEL) of SQGs, 79% percent of sediments would be expected to occasionally be associated with the toxic adverse effects on aquatic organisms because of Pb. While, cadmium exceeded the probable effect level (PEL),Khalid EL-MOSELHY | Professor | Ph.D. | Marine Pollution,The total concentrations of heavy metals (Cu, Zn, Pb, Cd, Fe, Mn, Ni and Co) were determined in surface sediments from the coastal area of the Red Sea in four cities (Ras-Gharib, Hurghada, Safaga
