“…OM in soil prevents the release of metals due to the formation of Metal-OM complex. This was in agreement with the findings of [18] who opined that OM content and other soluble compounds in soil influences the transfer of metals from soil to plants. As the amount of OM increases, there is atendency for more metals to be absorbed on the soilcomplex and hence reduce their mobility [19].The least amount of Cr recorded at station III may be due to higher association of the metal with residual non-extractable fractions which makes the metal less available.…”

The accumulation of heavy metals in agricultural soil is a source of concern because of food safety issues. The present study was aimed at evaluating the Transfer Factors(TFs) of potentially toxic metals (Cd, Cr, Cu, Pb and Zn) from soil into the food chain by assessing the levels of these metals in soils and vegetables (Carrot, Cabbage, Lettuce and Spinach) obtained from farmlands along River Delimi in Jos city. The metals content in soils and vegetables were determined using 210 VGP Model, Buck Scientific Atomic Absorption Spectrophotometer (AAS) after extraction with Aqua-regia. The data generated were analyzed using simple descriptive statistics followed by the determination of TFs calculated as the ratio of the concentrations of the metals in crops to the concentrations in soils. The results revealed that both the soil and crop samples collected at the study area contained more metals than those at the control site. Additionally, the metals generally had highest TFs values at the study area compared to the control site. The least TFs values for these metals in the crops at the control site could be attributed to the lower mean total metals content in the soils. This further suggests that plant absorption of these metals was mainly controlled by the content that is available in the soil. It is recommended that farmers should cultivate plant species (legumes, cereals, potatoes etc.) with low metal uptake and avoid the cultivation of crops such as carrots, spinach, lettuce that are known to accumulate high amount of metals. The metal transfer into food chain could also be reduced through cultivation of industrial crops such as Jatrophaand castor plants known for their high oil content. Furthermore Farm Yard Manure should be applied to the soil as it reduces the bioavailability of the heavy metals to the crops

Potassium (K) is one of the major essential nutrient elements that recently application of its organic or nano-chelate-fertilizers received increased attention. Cadmium (Cd) contamination in agricultural soils and environment is increasing due to over application of Cd-containing phosphate fertilizers. But few studies have been done about the environmental influences of K-nanochelate-fertilizers especially on Cd-polluted soils. Therefore, the effects of K-fertilizer application in different rates (0, 100 and 200 mg kg -1 soil) and forms (KCl, K 2 SO 4 and Knano-chelate) on Cd content and partitioning in Ocimum basilicum grown on an artificially Cd-contaminated calcareous soil (with 40 mg Cd kg -1 soil) were studied under greenhouse conditions. Cadmium decreased shoot-dry-weight (SDW); but did not affect root-dry-weigh and no consistent-trend was observed with applied K. Cadmium increased shoot and root Cd concentration or uptake. KCl and K 2 SO 4 increased shoot Cd concentration as compared to A c c e p t e d M a n u s c r i p t that of control; whereas, K-nano-chelate did not affect it. In Cd-treated-soils the mean value of Cd translocation-factor (ratio of Cd concentration in shoots to that of roots) decreased by 60% as compared to control. Application of 100 mg K-K 2 SO 4 and 100 and 200 mg K-nanochelate increased Cd-translocation-factor by 49, 59 and 112% in Cd-treated-soils, respectively. In Cd-treated-soils greater amounts of Cd accumulated in roots. K-nano-chelate could mitigate the adverse effect of Cd on SDW and Cd-accumulation in plants grown on Cdpolluted-soils, so the risk of Cd entrance to food-chain is reduced (however, in Cd-untreatedsoils, K-nano-chelate increased Cd translocation-factor higher than other K sources). In Cdpolluted-soils KCl was the most inappropriate fertilizer that may intensify Cd-accumulation in plants. However, it may be useful in phytoremediation of Cd-polluted soils.

This study was conducted to investigate the contamination level of heavy metals in soil and vegetables, chemical speciation, and their transfer to the edible part of vegetables. Metals were analyzed using inductively coupled plasma mass spectrometer (ICP-MS). The ranges of Cr, Ni, Cu, As, Cd, and Pb in agricultural soils were 3.7-41, 3.9-36, 3.7-46, 2.3-26, 0.6-13, and 4.5-32 mg/kg, respectively. The metals were predominantly associated with the residual fractions of 39, 41, 40, 40, 34, and 41 % for Cr, Ni, Cu, As, Cd, and Pb, respectively. Considering the metal transfer from soil to the edible part of vegetables, the mean transfer factors (TFs) were in the descending order of Cu > Ni > Cr > Pb > As > Cd. In the edible tissues of vegetables, the concentrations of As, Cd, and Pb in most vegetable samples exceeded the maximum permissible levels, indicating not safe for human consumption. Total target hazard quotient (THQ) of the studied metals (except Cr) from all vegetables were higher than 1, indicated that if people consume these types of vegetables in their diet, they might pose risk to these metals. Total values of carcinogenic risk (CR) were 3.2 for As and 0.15 for Pb which were higher than the US Environmental Protection Agency (USEPA) threshold level (0.000001), indicating that the inhabitants consuming these vegetables are exposed to As and Pb with a lifetime cancer risk.
