“…High concentrations (i.e., above background levels) coupled with a high coefficient of variation suggest anthropogenic inputs for metal elements (Manta et al 2002). However, some researchers (Aucejo et al 1997;Facchinelli et al 2001) suggest that wastewater is the main source of these elements in Fig. 3 (continued) agricultural soils, especially in densely populated areas with inefficient cleaning processes.…”

A detailed investigation was conducted to evaluate heavy metal sources and their spatial distribution in agricultural fields in the south of Tehran using statistics, geostatistics, and a geographic information system. The content of Cd, Cu, Co, Pb, Zn, Cr, and Ni were determined in 106 samples. The results showed that the primary inputs of Cr, Co, and Ni were due to pedogenic factors, while the inputs of Zn, Pb, and Cu were due to anthropogenic sources. Cd was associated with distinct sources, such as agricultural and industrial pollution. Ordinary kriging was carried out to map the spatial patterns of heavy metals, and disjunctive kriging was used to quantify the probability of heavy metal concentrations higher than their recommended threshold values. The results show that Cd, Cu, Ni, and Zn exhibit pollution risk in the study area. The sources of the high pollution levels evaluated were related to the use of urban and industrial wastewater and agricultural practices. These results are useful for the development of proper management strategies for remediation practices in the polluted area.

“…These concentrations were comparable to the concentrations of Ni (215-mg kg -1 ) and Co (0.10.2-mg kg -1 ) found by Romero et al (2012) in citrus leaf samples collected from cultivated lands near mines, and lower than the concentrations of Pb 0.82.6-mgkg -1 ) and Cd (<0.01 mgkg -1 ) in our leaf samples. In spite of that, concentrations of Pb and Ni were still below toxic levels in citrus leaves mentioned by Aucejo et al (1997) which were 1020-mgkg -1 for Pb and 50100-mgkg -1 for Ni.…”

A UTOMOBILE exhausts are considered the main source of air pollution with heavy metals. Airborne pollutants are precipitated on soils surrounding highways causing serious ecological hazards. The current study aimed at evaluating levels of Pb, Ni, Co and Cd in surface (015-cm) and subsurface (1540-cm) soils nearby Cairo-Alexandria agricultural highway, and their accumulation in plants grown thereon. Seven locations were sampled at interval distances 50 meters on both sides of the highway road near Toukh city (Qualubya Governorate). Cabbage and citrus plants were also sampled and separated into its parts. Results revealed that the investigated soils are contaminated with Pb, Ni and Cd. These contaminants were brought to the subsurface layers of the soil at relatively high concentrations. Total and DTPA-extractable contents of Pb and Ni in the top surface soil decreased with increasing the distance from the high way on both sides of the road. Moreover, concentrations of these metals in the cabbage parts were significantly correlated with their total and DTPA-extractable contents. However, Co and Cd in soils seemed to be not affected by the exhausts of the cars on the highway. Heavy metals decreased in cabbage parts as follows: root > stem > outer leaves > inner leaves > core. Calculated BAF values for Pb, Ni and Co were very low indicating that cabbage might be an excluder for these metals whereas, their transfer from roots to shoots (transfer factor, Ts) were high. Heavy metal concentrations in citrus decreased as leaves > flavedo > albedo > segments. Generally, concentrations of heavy metals in plants particularly Pb exceeded the permissible limits. 19

“…Interpretation of foliar analysis was made by comparing results obtained with previously established standard and toxic values for each element (Aucejo et al, 1997;Legaz et al, 1995). In order to assess the transfer of metals from soil to plants, TF was calculated with total element concentration of soils.…”

“…The uptake by trees is usually lower than by small vegetables (Aucejo et al, 1997;Caselles, 1998;Oliva et al, 2008), but the problems can be enhanced when crops are cultivated close to contaminated mining sites (Pinochet et al, 1999).…”
