“…Average (292 mg kg -1 ), maximum and minimum Pb concentrations in MI soils far exceeded the values found in the other 3 urban farms ( Figure 2). The average value for Pb was also greater than the median or mean concentrations of toxic metals in urban soils from some European cities, as compiled by Hiller et al (2016) and Poggio et al (2009). In a recent study by Antoniadis et al (2017b) undertaken in four gardens located in the vicinity of a mine dump area in Germany, Pb was the single most important element causing a health risk related to consumption of vegetables grown in the gardens.…”

Heavy metal pollution in urban-grown organic vegetables and soils of the province of Sevilla, Spain Sources of heavy metal pollution in vegetables can be varied. The focus of this study was to determine the factors affecting trace metal pollution in soils and vegetables that are grown on community urban and periurban organic farms in Spain. Results of this study shown that soil and dust deposition affected plant composition more than other anthropogenic sources, such as traffic loads, which showed a small incidence on the farm located in the largest city, Sevilla. Lettuce and broad bean samples taken at one urban farm showed high concentrations of crustal metals Fe, Ca, Mn and Cr, which was thought be due to Saharan dust deposition. The buildup of soil Cu concentration, due to the use of Cu-based fungicide over the long term, was observed on the farm where cultivation had occurred over a long period of time. On this farm, Pb in soil and vegetables had reached levels that could pose a risk to human health and/or the environment due to the random and uncontrolled locations of the disposal of demolition wastes containing lead-based white paints. The increased risks for consumers due to these several sources acting simultaneously demonstrate the need for a careful selection of the urban soils that are intended for agricultural use. Soil organic matter counteracted Pb availability, hence organic management and intensive use of organic amendments are recommended for urban farms.

The environmental quality of soil in the central part of the Northern Plateau of Spain has been analyzed by studying the heavy metal content of 166 samples belonging to the horizons A, B and C of 89 soil profiles. The analysis to assess the environmental risk of heavy metals in the soil was carried out by means of the spatial distribution of nine heavy metals and the use of several pollution indices. The results showed that the concentration values of heavy metals (normalxfalse¯ ± S) in the superficial soil horizons were the following: With a total of 6.71 ± 3.51 mg·kg−1, the contents of Cd is 0.08 ± 0.06 mg·kg−1, Co is 6.49 ± 3.21 mg·kg−1, Cu is 17.19 ± 10.69 mg·kg−1, Cr is 18.68 ± 12.28 mg·kg−1, Hg is 0.083 ± 0.063 mg·kg−1, Ni is 12.05 ± 6.76 mg·kg−1, Pb is 14.10 ± 11.32 mg·kg−1 and Zn is 35.31 ± 14.63 mg·kg−1. These nine metals exceed the values of the natural geological background level of Tertiary period sediments and rocks that form part of the Northern Plateau in Spain. Nemerow and Potential Ecological Risk indices were calculated, with the “improved” Nemerow index allowing pollution within the soil superficial horizons to be determined. The data obtained indicated that the majority of the soil (54.61%) showed low to moderate contamination, 22.31% showed moderate contamination and 21.54% of the samples were not contaminated. If we consider the Potential of Ecological Risk Index (RI), the largest percentage of soil samples showed low (70.79%) to moderate (25.38%) ecological risk of potential contamination, where the rest of the soil presented a considerable risk of contamination. The nine trace elements were divided into three principal components: PC1 (Cu, Cr, Ni, Co and Zn), PC2 (As and Hg) and PC3 (Cd). All metals accumulated in the soil came from parent rock, agricultural practices and the run-off of residual waters towards rivers and streams caused by industrial development and an increase in population density. Finally, cartography of the spatial distribution of the heavy metal contents in the soil of the Northern Plateau of Spain was generated using Kriging interpolation methods. Furthermore, the total heavy metal contents in three soil orders present in the area, namely Entisols, Inceptisols, and Alfisols, were analyzed. Other soil parameters, such as the organic matter content, pH, clay content and cation exchange capacity, was measured to determine their influence on and correlation with the heavy metal contents.

“…Iron showed a strong positive correlation with all other elements. Potentially toxic elements are bound to ferric iron minerals such as goethite and hematite with high adsorption capacities for many toxic elements and occur in oxidized soil and dust [54]. Strong positive correlated elements also suggest a similar source or origin [55].…”

The purpose of this study was to determine the concentration, sources of pollution and health risks associated with 16 potentially toxic elements (PTEs) in 120 urban road dust samples in the city environ of Lagos, southwest, Nigeria. For all road dust samples, Zn, Se, Mo, Ag, Cd and Pb were higher than background values as defined by Upper Continental Crust (UCC) values, whilst 50, 96, 3, 20, 20, 5 and 5% of the samples showed higher values for U, Cu, V, As, Cr, Ti and Fe, respectively. The spatial distribution maps showed that pollution hotspots for Pb, Zn, Cu, Cr, Se, Ag, Cd and Mo were concentrated in densely populated areas with a high volume of traffic and industrial areas such Ikeja, Ojo, Alimosho and Kosofe regions. Ninety five percent of the samples provided a Pollution Load Index (PLI) greater than 1, indicating the presence of pollution inputs. The calculated Contamination Degree (CD) was between 10 -174 for PTE's with an average of 58, exhibiting a moderate to very high degree of contamination. The potential ecological risk index (RI) ranged from 39 -3496, with a mean value of 678 where 7% of the samples provided a low ecological risk index, 5% a moderate risk, 34% and 38% a considerable and very high ecological risk. The non-carcinogenic health risk index showed that Mo, Pb and Co accounted for 87% of the Heath risk index value for both children and adults with a low to moderate exposure risk following the order: dermal > ingestion > inhalation. The carcinogenic risk showed that Ni posed no carcinogenic risk in the dust, Co and As were within low risk, Pb and Cd posed a low and moderate carcinogenic risk to both children and adults in the study area. Road dusts from industrial and densely populated residential areas with high traffic influx exhibited a higher pollution and health risk index compared to less densely populated residential areas in Lagos. This confirmed vehicular traffic as the main source of the PTEs in the dust samples of the study area.
