“…Ogunyemi et al (2003), observed the same trend in a study in Ibadan. This observation also agreed with the findings of Sürücü et al, (2018). The same trend was reported by Chen et al (2010).…”

“…Similar pattern was recorded for the concentrations of Cd and Mn at PRF. The increased Pb and Cd concentration in the soils of sites near the road could probably result from the lubricating oil and/or old tires of vehicles used on the roads (Sürücü et al, 2018). However, the concentrations of each of these metals in the soil were below the permissible limit set out by WHO/FAO (2011).…”

Farmers have long considered urban agriculture as a panacea to urban food insecurity. However, growing food in cities is faced with many challenges like food contamination. Past studies on leafy vegetables focused on vegetables cultivated in urban centres. However, this paper aimed to determine and compare the level of heavy metals concentrations in soil and leafy vegetables in Urban Expressway Farms (UEF) and Peri-urban Road Farms (PRF) in Lagos, Nigeria. These two locations were purposefully selected. Soil Auger was used to drill holes to the required soil depth to collect soil samples. Sample of Amaranthus hybridus, Celosia argentea and Corchorus olitorius were collected using “envelope” principle. Pb, Cd and Mn residues in the samples were digested and determined using Atomic Absorption Spectrophotometer. The collected data were analysed using mean, standard deviation and Analysis of Variance. The mean pH value for UEF soil is 6.5 while PRF soil is 6.6. The highest Pb (0.93±0.06) was recorded in Celosia argentea at UEF. The highest mean concentration of Cd (0.51±0.11) was recorded in Amaranthus hybridus at UEF. The highest concentration for Mn was recorded in Amaranthus hybridus (0.98±0.02) at UEF. The concentrations of Pb in Celosia argentea at UEF 5 m from the expressway and Cd concentration in Amaranthus hybridus at 10 m from expressway were above the WHO/FAO permissible levels in vegetables. Level of heavy metal residue observed in soil and vegetables under this study were mostly influenced by the location of the farm-environment and not mainly the vegetable type. The relative concentrations of Pb and Cd in all the three leafy vegetables raise some serious environmental concerns and need to be monitored regularly to prevent consumption of contaminated leafy vegetables. Farmers are encouraged to cultivate in fields far away from expressway.

“…These findings are supported by the fact that these parts are close to the main road passing through the area. Most probably, these parts are highly affected by most probably by atmospheric deposition of heavy metals from vehicle exhausts, and excessive fertilizers and pesticides applications as well, these findings agree with results reported by (Sürücü, Mohammad, Günal, & Budak, 2018).

In this study, ninety agricultural soil samples were collected from Kalar and Quratoo subdistricts east of Iraq. Where soil samples have been analyzed to quantify concentrations of nine soil physicochemical properties and sixteen heavy metals by using ICP-OES with other analyzing tools. Analysis results showed that significant variations exist in concentrations of the investigated parameters among sampling sites. Multivariate statistics have been conducted to identify relationships between heavy metals and soil properties. Multiple correspondence analysis MCA showed strong relationships for total nitrogen T.N. with Cu, Ni, and Hg. Agglomerative hierarchical clustering (AHC) and factorial analysis (FA) divided soil property relationships with heavy metals into three main categories in terms of heavy metals nature; naturally occurred, generated from anthropogenic sources, and of weak relationships. Spatial variation map showed that soil properties in middle parts of the study area are more impacted by heavy metals that came from anthropogenic sources. This study aids to improve the environmental protection and monitoring of agricultural lands in Iraq.

“…Lead (Pb) is one of the most important environmental pollutants, especially in regions with high anthropogenic activities [155], and in toxic concentrations it negatively affects crop biomass as well as yield [156]. At high concentrations, it leads to reduced growth, ROS accumulation, irregular phytomorphology, and cell death [157].…”

Abiotic stressors, such as drought, heavy metals, and high salinity, are causing huge crop losses worldwide. These abiotic stressors are expected to become more extreme, less predictable, and more widespread in the near future. With the rapidly growing human population and changing global climate conditions, it is critical to prevent global crop losses to meet the increasing demand for food and other crop products. The reactive gaseous signaling molecule nitric oxide (NO) is involved in numerous plant developmental processes as well as plant responses to various abiotic stresses through its interactions with various molecules. Together, these interactions lead to the homeostasis of reactive oxygen species (ROS), proline and glutathione biosynthesis, post-translational modifications such as S-nitrosylation, and modulation of gene and protein expression. Exogenous application of various NO donors positively mitigates the negative effects of various abiotic stressors. In view of the multidimensional role of this signaling molecule, research over the past decade has investigated its potential in alleviating the deleterious effects of various abiotic stressors, particularly in ROS homeostasis. In this review, we highlight the recent molecular and physiological advances that provide insights into the functional role of NO in mediating various abiotic stress responses in plants.
