“…This suggests that Fe concentration in the various vegetables was safe for consumption. However, In Pakistan, Nisa et al (2020), reported low Fe concentration in vegetables contrariwise, to the Fe concentration reported by Eid et al (2020), in Corchorus olitorius L. cultivated in Abha -Saudi Arabia.…”

Several studies have been carried out on leafy vegetables but many did not assess the heavy metals in soil and leafy vegetables along urban-peri-urban gradient of Lagos State. The study assessed the concentration of heavy metals in the soil and leaves of three commonly consumed vegetables (Amaranthus hybridus, Celosia argentea and Corchorus olitorius) in Lagos State. Sampling was conducted in 2019 and 2020. Fe, Pb, Cu and Cd residues in the soil and the leafy vegetables samples were digested and determined using Atomic Absorption Spectrophotometer. The collected data were analyzed using simple descriptive statistics and Analysis of Variance. The range of values of the mean concentrations of the heavy metals in soil showed that Fe =20.76±0.20mg/kg – 107.83±17.02mg/kg, Pb = 0.13±0.07mg/kg –2.47± 0.45mg /kg, Cd=0.08 ± 0.02mg/kg – 6.07 ± 2.90mg/kg and Cu = 0.24±0.11mg/kg–40.20±4.90mg/kg. The range of values of the mean concentrations of the heavy metals in the leafy vegetables showed that Fe = 113.10±14.05mg/kg – 1.51±0.02mg/kg, Pb=0.51±0.09mg/kg - 0.001±0.001 mg/kg, Cd=0.51±0.01mg/kg-0.001±0.01amg/ kg, Cu=7.54±0.97 mg/kg - 0.36±0.03mg/kg. The Level of heavy metals residues in soil and the three leafy vegetables were at safe levels set by WHO/FAO except for Pb and Cd found in vegetables in Ketu and Yaba study locations.

“…The soils heavy metals content from three (3) different locations along Rivers Jakara and Getsi were presented in Table 5 and 6 (Zhou et al, 2019), lower soil pH and higher abundance of organic matter favour heavy metals uptake by crops Hou et al, 2019;Eid et al, 2020;Liu et al, 2020 andOuyang et al, 2020). Alkaline pH lowers heavy metals solubility (Swiatek et al, 2019), therefore alkaline soil retain heavy metals.…”

Three samples of soil, lettuce and cabbage were collected from three sites along River Jakara (Zungeru, Airport Road and P.R.P) and River Getsi (Gama, Gayawa and Getsi) and were analyzed for Fe, Pb, Zn, Cu, Mn, Cr, As, Ni, Cd, Co, and Hg content using Atomic Absorption Spectrophotometer and the toxicological indices of the soils and vegetables were determined. The metal content of the soil exceeded the FAO/WHO approved limits in irrigation soil. Pb and As exceeded the approved limit in all the vegetables and levels of Zn, Cr and Cd in the lettuce collected from sites along River Getsi exceeded the approved limits by FAO/WHO as the irrigation area were dotted with leather, paint, foam and chemical industries coupled with the activities of auto mechanics, furniture and wood processing companies. It was found that lettuce accumulated more toxic metals of Pb, Cr, As, and Cd than cabbage with values ranging from 0.59 – 3.48, 0.2 – 0.4, 2.2 -5.0 and 0.6 – 3.12mg/Kg respectively. The soil Pollution Load Index (PLI) in all the sites was found to be above 1 while the Degree of Contamination (Cd) was found to be from highly to extremely contaminated soils with the lowest Cd of 2.67 found in Gama while the highest was 5.35 in Getsi site. The Geometrical Index (Igeo) ranged from 0.07 in samples from P.R.P to 1.17 in samples collected from Zungeru suggesting an uncontaminated to moderately contaminated soils. The Bioaccumulation factor showed highest transfer of Fe and Zn in both cabbage and lettuce and most metals have Transfer Coefficient value above 1 suggesting excessive transfer. Based, on the above findings, Government at all levels should initiate policies that will mitigate the effects of heavy metals in the study area.

“…Since there is not much literature available relating to the establishment of regression models specifically for the absorption of metals by A. esculentus grown in media combined with varying sewage sludge concentrations, the obtained data were compared with studies that evaluated similar concepts using regression models pertaining to alternative crops. When judged against the tissues of A. esculentus in which Cd variability was 77.7-92.5%, Cd variabilities within the plant components for cucumber [1], barley [43], kidney bean [47], garden pea [48], Corchorus olitorius [49], Eruca sativa [50], and spinach [51] were 49-76%, 45-88%, 44-61%, 25-67%, 69-75%, 49-81%, and 83-88%, respectively. Bešter et al [44] used models to measure the impact of Cd in tomato and endive, which exhibited R 2 values of 41% and 90%, respectively.…”

Prediction models were developed to estimate the extent to which the metals Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn were taken up by the fruits, the leaves, the stems, and the roots of the okra plant, Abelmoschus esculentus (L.) Moench., grown under greenhouse conditions in soil modified with a spectrum of sewage sludge concentrations: 0, 10, 20, 30, 40, and 50 g/kg. All the metals under investigation, apart from Cd, were more concentrated in the A. esculentus roots than in any other organ. Overall, the sum of the metal concentration (mg/kg) within the varying plant tissues can be ranked in the following order: roots (13,795.5) > leaves (1252.7) > fruits (489.3) > stems (469.6). For five of the metals (i.e., Cd, Co, Fe, Mn, and Pb), the BCF was <1; for the remaining four metals, the BCF was >1, (i.e., Cr, 1.074; Cu, 1.347; Ni, 1.576; and Zn, 1.031). The metal BCFs were negatively correlated with the pH of the soil and positively correlated with soil OM content. The above-ground tissues exhibited a TF < 1 for all metals, apart from Cd with respect to the leaves (2.003) and the fruits (2.489), and with the exception of Mn in relation to the leaves (1.149). Further positive associations were demonstrated for the concentrations of all the metals in each examined plant tissue and the corresponding soil metal concentration. The tissue uptakes of the nine metals were negatively correlated with soil pH, but positively associated with the OM content in the soil. The generated models showed high performance accuracy; students’ t-tests indicated that any differences between the measured and forecasted concentrations of the nine metals within the four tissue types of A. esculentus failed to reach significance. It can, therefore, be surmised that the prediction models described in the current research form a feasible method with which to determine the safety and risk to human health when cultivating the tested species in soils modified with sewage sludge.
