“…The REE could be an appropriate indicator to define pedogenetic processes, weathering condition and source identification of soils [12,25]. The REE composition of SR surface soils is significantly dependent on parent materials [28,31]. So, the investigation of sewage irrigation on REE content could be helpful to determine soil geochemical variations in this area.…”

The present study identifies the effects of sewage irrigation on the surface soils geochemistry and the concentration of heavy metals in plants of Sabzevar area, which were irrigated for a long time by wastewater. This study shows that the sewage irrigation has led to decreasing pH and increasing organic matter, and also it makes the accumulation of P 2 O 5 , high-field-strength elements (Ga, Ta, Th, U and Y) and heavy metals (Cd, Co, Cu, Pb, Sn and Zn) in contaminated soils. Likewise, the concentration of rare-earth elements (REE) in contaminated soils is more than background samples with moderate enrichment of light REE compared with high REE in REE pattern diagram (mean La N /Lu N = 5.77). The calculated transfer factor and enrichment factor indexes in plants grown on the polluted soils are significantly higher than the control samples which show the heavy metal enrichment in the contaminated samples. Although the cultivated crops on this area (maize, beet, alfalfa, barely) are used only for animal feed, the heavy metal analysis indicated that the concentration of Cr, Cu, Ni and Pb in these plants, especially alfalfa and maize, is more than the maximum permitted levels defined in different standards.

“…The average concentration of vanadium and nickel in industrial areas was higher than residential areas. Therefore, it can be inferred that because nickel is released from fossil fuels into the environment [20,26], through the ceramics industry, the production of special batteries, electronics industry, manufacturing of steel tools and equipment enters the environment [35], and the release of vanadium into the environment is mainly associated with industrial resources, especially oil refineries and coal power plants [21,36], for these reasons, the amount of nickel and vanadium in the soil of industrial areas were higher than residential areas.…”

“…Heavy metal spatial distribution data helps researchers identify areas where hazards are high and then present them to decision makers so that repairing methods can be implimented [22,23]. In recent years, many studies have been conducted on heavy metal pollution, source identification, distribution pattern, pollution rate and human health risks worldwide [2,4,[24][25][26]. Ruiz-Fernandez et al [9] showed the spatial and temporal distribution of heavy metal concentrations and their enrichment in Mexican soils.…”

This study was conducted in 2017 with the aim of determining the distribution of heavy metals lead, nickel, cadmium, vanadium and the parameters of acidity, electrical conductivity and organic matter in the surface soils of the city of Khorramabad. Sampling was performed monthly from 12 stations and was repeated 3 times in the autumn. The highest amount of cadmium was observed in the soil samples of industrial areas of the city in the two sampling periods of October and December to be 7 ppm. A comparison of the mean measured values of heavy elements showed that the highest average amounts of heavy elements are in industrial areas and the lowest in residential areas. The lowest amount was measured in 8 th and 11 th stations at 2 ppm. The highest amount of lead in the 6 th station, a bustling area, was measured to be 22 ppm. The average nickel in industrial areas was higher than other areas. In industrial area, during the sampling period of October, its amount was determined to be 58 mg/kg. The highest amount of vanadium was recorded in staion9 at 52 mg/kg. Lead has a significant correlation with nickel, cadmium and soil acidity. This correlation is 0.01% for acidity and cadmium variables and 0.03% for nickel. Nickel has a significant correlation with cadmium and vanadium at the level of 0.01%. The results indicate that the surface soil of the city of Khorramabad is not contaminated with the studied metals. In general, the results showed that both human and natural factors are always involved in the distribution and concentration of heavy metals.

“…The landscapes under consideration do not receive any specific compounds, except for oxygen and various solid, liquid and gaseous products of life activity of organisms. Most of the sub stances entering the recreation areas are transported by air from nearby localities (Mazhari et al 2018). In recent years, pollution of these landscapes by exhaust fumes from cars and motorboats has become widespread.…”
