| Abstract | ||
| Port Said is considerd as an urbanized and industrialized city which has a rapid activity over the last few decades, and many urban environments there have metals which continuously emit gases which are seriously threatening the humankind. Ground magnetic susceptibility (MS) was carried out and soil samples were collected from selected sites of possible high risk as well as low ones in order to determine the contamination sources of heavy metals. An MS survey was carried out in the industrial area (sites A and B) and the solid-waste dump site in Port Said city (site C). MS maps of the three sites show anomalies of high values which indicate that these sites mostly affected by contamination. Ten of heavy metals concentrations (Fe, Mn, Mo, Cd, Ni, V, Pb, Cu, Co, and Zn) were calculated in the collected samples. In addition, the factor of contamination, geochemical accumulation, pollution load and Nemerow pollution indices were calculated to test heavy metals contamination in the selected sites. Sites (A & B) give a higher degree of contaminated with Cd, Pb, Ni and Zn where the industrial activities are located. Also, site A shows a moderate to low contamination with Mo, V, Fe, Co, Cu, and Mn while site B shows that the contamination originated mainly from the iron processing industries. Also, Nemerow pollution index shows that the site A represents a higher level of pollution than site B which has the moderate level of pollution, while site C represents the warning line of pollution which means that the heavy metal exposures have many consequences and is generally not safe. Finally, this study proves that the environmental magnetism used successfully as a proxy to heavy metal pollution in industry and topsoil of an open landfill and similar areas. | ||
