原始语种摘要: To assess the roadside soils contamination with Pb, Cd, and Zn, 34 soil samples were collected along Alexandria-Marsa Matruh highway, Egypt, and analyzed by using the atomic absorption. The contamination with these metals was evaluated by applying index of geoaccumulation ( I g e o ) , contamination factor (CF), pollution load index (PLI), the single ecological risk index ( E i ) , and the potential ecological risk index (PERI). The average concentrations of Pb, Cd, and Zn were 38.2, 2.3, and 43.4 μ g/g, respectively. I g e o indicates the pollution of soil with Pb and Cd as opposed to Zn. E i shows that the roadside soils had low risk from Pb and Zn and had considerable to high risk from Cd. Most of the samples (62%) present low PERI risk associated with metal exposure and the rest of...
