“…In the previous study, the Cu levels in agricultural soil sampling sites of Jiangsu Province ranged from 14.12 with 52.10 mg/kg [23], which was lower than what we evaluated in Lishui District, indicating that the pollution of Cu in agricultural soils alongside the highways in Lishui District might be more serious than that in other areas. The results stand in line with the previous studies [24][25][26].…”

The agricultural soil alongside highways has experienced multiple potential ecological risks from human activities. In this study, 100 soil samples near the highways were collected in Lishui District, Nanjing City. Using the single-factor pollution index, the Nemerow comprehensive pollution index, and the potential ecological risk index, the study investigated the heavy metal contents and distribution in roadside agricultural soil. PCA and a multiple regression model were applied to quantitatively analyze the spatial relationships between sampling soil heavy metal accumulation and the surrounding man-made landscape. The mean contents of Cu and Pb exceeded the background, while Cd, Cr, and Zn were lower than that. The potential ecological risk index exhibited a very low ecological hazard and only Cr in soils rarely showed moderate risk. Furthermore, quantitative analysis for the sources of contamination revealed that agricultural practices were the dominant contributors to the heavy metals, including Cd, Cu, and Zn, while road and heavy industrial practices contributed to Cr and Pb. The study provides sources of heavy metal pollution from human activities in roadside agricultural land and serves as a reference for ecological restoration.

“…Theses heavy metals are released into the roadside environment as a result of mechanical abrasion and normal wear and tear. Soil tends to accumulate metals on a relatively long term basis since many metals in the soil are mobile [3][4][5][6][7][8][9][10][11].…”

Heavy metal concentration in road side soils with its potential ecological effects draws much attention in the developing countries. This necessitates the study of their accumulation in the road side soils of Maiduguri (longitude 11° 13' N; latitude 13° 05' E), to ensure effective protection of soil from the potential loss of its fertility. In this study, roadside soil samples from major roads (Baga road, Bama road, Ngala road and Kano/Jos road) of Maiduguri were collected and determined the levels of heavy metals (As, Cr, Mn, Fe, Ni, Pb, Zn, Cd, and Cu) in the roadside soil using the Perkin-Elmer analyst 300 Atomic Absorption Spectroscopy (AAS). The results showed that in all the sampling locations, Mn, Zn, Fe and Pb have higher concentration of 137.4±0.04 mg/kg, 392.11±0.07 mg/kg, 13491.70±0.07 mg/kg and 928.50±0.04 mg/kg respectively in roadside soil as compared with Cd of concentration ranges from 0 to maximum of 0.87±0.04mg/kg in Ngala road. The concentrations of Pb and Cd in the soil samples were higher than the recommended value of 48 mg/kg and 5.0 mg/kg respectively. The higher concentration of these metals in the roadside soil samples may be attributed to human activities and traffic volume. Therefore, there is need to further study the concentrations of such heavy metals in agricultural soil, plants and vegetables grown in that area, animals that fed on the plants and any other source that directly or indirectly link to the source of food of the populace.

“…The results showed a positive strong correlation of Cu and Pb with the other metals (except for Cr), with the highest correlation coefficient being between Cu and Pb, implying that these latter two metals originated from the same source. The deposition of these metals in the soil is associated with the emissions of fuel engines [42].…”

This study aims to evaluate the concentration of the heavy metals (Co, Cd, Cr, Cu, Ni, Pb, and Zn) and their ecological risk in soils adjacent to the power generators of Ramadi city, Iraq. The soil samples were collected from a depth of 20cm. The obtained results showed that the mean concentrations of heavy metals (HMs) are ranked as in the following order: Cr (360.90mg/kg) > Ni (283.65mg/kg) > Zn (190.96mg/kg) > Pb (130.75 mg/kg) > Cu (36.54 mg/kg) > Co (16.62 mg/kg) > Cd (2.55 mg/kg). The mean values of HMs concentration exceed the international guidelines. The result of correlation matrix analysis at P £ 0.05 showed significant correlations between the concentrations of HMs. These correlations are interpreted in the context of a common source of pollution and/or common origin. Results of the potential ecological risk factor assessment of metal i (Eir) in soil adjacent to the power generators of Ramadi city showed that the Eir values take the following descending order: Ni (354.56, very severe) > Cd (255.31, severe) , Co (207.77, severe) > Zn (88.69, heavy) > Cu (25.73, light) > Cr (17.43, light) > Pb (12.0, light). The potential ecological risk index (RI) values are classified as severe ecological risk for all studied heavy metals. This study provides the environmental protection managers and decision-makers with important information about the risk of using electrical generators in residential neighborhoods.
