“…The mean concentrations of heavy metals in spinach at Jimeta dumpsite decreased in the following order: Fe (3.7 mg/kg) > Pb (0.18 mg/kg) > Cu (0.12 mg/kg) > Cr (0.07 mg/kg) > Cd (below limit of detection), compared to the metal mean concentration in spinach at Ngurore dumpsite with lower concentration of heavy metal which decreased in the order: Fe (2.5 mg/kg) > Pb (0.16 mg/kg) > Cu (0.14 mg/kg) > Cr (0.02 mg/kg) > Cd (below limit of detection). This result differs from the report of Nanven et al (2015), who reported that spinach, bioaccumulated the metals Fe, Mn, Zn, Cd, Ni and Pb in the order Fe > Mn > Zn > Cd > Ni > Pb. This could be a reflection of the concentrations of the metals in the soil.…”

“…This could be a reflection of the concentrations of the metals in the soil. Nanven et al (2015) also reported that the concentration of iron was highest in almost all the vegetables similar to this study. The higher concentration of Fe noted in this study could be as a result of its oxygen carrying ability for chlorophyll production and also for protein synthesis (Kashif et al, 2009).…”

The study analyses the health risk assessment of the concentration of Iron, Lead, Copper, Chromium, and Cadmium heavy metals in vegetables grown near dumpsites of Jimeta and Ngurore areas of Adamawa State, Nigeria. Vegetables mainly Spinach (Spinacia oleracea) and lettuce (Lactuca sativa) were collected in triplicates and analyzed using Atomic Absorption Spectrophotometer Buck 210VGP (AAS). The result revealed that heavy metals detected in spinach at Jimeta dumpsite decreased in the following order: Fe (3.7 mg/kg) > Pb (0.18 mg/kg) > Cu (0.12 mg/kg) > Cr (0.07 mg/kg) > Cd (below limit of detection), compared to the metal concentration in spinach at Ngorure dumpsite with lower concentration of heavy metal which decreased in the order of: Fe (2.5 mg/kg) > Pb (0.16 mg/kg) > Cu (0.14 mg/kg) > Cr (0.02 mg/kg) > Cd (below limit of detection). Other result for Spinach in Jimeta decreased in the order Fe (3.31mg/kg) > Pb (0.2mg/kg) > Cu (0.11mg/kg) > Cr (0.05mg/kg) > Cd (ND) beyond the limit of detection while Lettuce decreased in the order Fe (22.54mg/kg) > Cu (0.31mg/kg) > Pb (0.12mg/kg) > Cr (0.07mg/kg) > Cd (ND) beyond the limit of detection. Fe is the most abundant element in the vegetables with a mean value of 21 mg/kg followed by Pb (0.177 mg/kg). The analyses of paired T-test for vegetables in Ngurore and Jimeta at 0.05 level of significant confirmed that Cu and Cr showed no statistically significant difference in their concentration level while Fe and Pb confirmed that there was statistically significant difference in their concentration level. However, the detection of heavy metals in these vegetables calls for close environmental monitoring and adequate public awareness. This is necessary to discourage further pollution which could lead to high metal concentration and metal poisoning in vegetables and invariably humans that consume them.

Heavy metal contamination arises from the disposal of used engine oil which is one of the environmental problems in Nigeria and is more widespread than crude oil pollution. The aim of this research is to evaluate the human risk of heavy metal and its bioaccumulation factor in soil and some edible vegetables around active auto-mechanic workshop in Chanchaga Minna Niger State, Nigeria. Soil samples were collected at 15-20 cm depth with the aid of soil auger and a control sample was also collected (generally about 100 m away from each cluster) where neither car repairs, industrial nor commercial activities are carried out. All vegetable Fluted pumpkin (Telfairia occidentalis), Jute mallow (Corchorus olitorius), water leaf (Talinum triangulare), Roselle (Hibiscus sabdariffa) and African spinach (Amaranthus cruentus) samples were collected from farms close to the workshop. The soil samples were collected at random and physicochemical parameters such as pH, total nitrogen, total phosphorus, organic matter and exchangeable cations (i.e., K+, Mg2+ and Na+) using a standard method and concentrations of the heavy metals in soils and vegetables, As, Cd, Hg and Pb were analyze using Flame Atomic Absorption Spectrometer (FAAS). The bioaccumulation factor and the risk health risk assessment from the consumption of these vegetables was calculated using standard methods and formulas. The physicochemical properties shows a significant (P<0.05) different in the auto mechanic soil and the control soil. The soil samples from auto-mechanic workshops in Chanchaga revealed elevated levels of heavy metals than the control. The concentration of all heavy metal in vegetables exceeded the permissible limits of 0.5, 0.2, 0.1 and 0.3 mg/kg for As, Cd, Hg and Pb respectively as prescribed by FAO/WHO. The Bioaccumulation factor shows that metals are transferred from the contaminated soil to the vegetable with Hg in Talinum triangulare greater than one. The estimated health risk shows that children are more prone to toxic elements from the consumption of these vegetables grown around auto mechanic site. The research conclude that these auto mechanic workshops accumulate potentially toxic elements in the soil and do have a negative impact on the plants, human and surrounding environment, which calls for stricter regulation on their location within cities.
