There is an increasing global concern for adverse effects of inorganic fertilizer and pesticides applied to agricultural soils. This study investigated metal speciation in soil and health risk assessment of Jute mallow (Corchorus olitoriuos) from a farm settlement in Ikorodu, Lagos State. Soil samples were collected according to the set standard procedure, sequentially extracted and analyzed for selected heavy metals using standard methods. Results showed that chromium (Cr) was associated with reducible fraction (Fe-Mn) for top soil, while cadmium (Cd), manganese (Mn), and copper (Cu); lead (Pb) and nickel (Ni); and Cr were predominantly bound to carbonate, reducible and residual mineral components respectively for sub-soil. The results of Contamination Factor (CF), Contamination Degree (CD), Pollution Load Index (PLI) and Geoaccumulation Index (I geo ) showed that the soil samples were not polluted for all the investigated metals. The Cd level in the soil (13.54 ± 1.21 mg•kg −1 ) and vegetables (0.83 ± 0.05 mg•kg −1 ) were above the USEPA critical permissible limit of 3.0 mg•kg −1 and 0.1 -1.2 mg•kg −1 respectively. The daily intake of estimated selected heavy metals from the vegetable ranged from 8.8 × 10 −03 to 1.4 × 10 −02 for adult and 3.8 × 10 −03 to 1.1 × 10 −02 for children while the Hazard Quotient (HQ) for adults ranged from 5.4 × 10 −05 to 1.1 × 10 −01 and that of children ranged from 8.3 × 10 −03 to 1.4 × 10 −02 . The cancer risk (CR) values of heavy metals in the soil ranged from 1.02 × 10 −11 to 9.90 × 10 −10 and 4.45 × 10 −09 to 8.61 × 10 −09 for children and adults respectively. The level of cancer risk was below the threshold values (10 −4 -10 −6 ) which USEPA considered as unacceptable risk.

“…Daily metal intake estimate and hazard quotient for bush okra in investigating site. RfD established at 1.5 mg•kg −1 per day (equivalent to 105 mg per day)[51].This value was also lower than that recommended by the US National Council[90] for Cr 3+ : from 0.05 to 0.2 mg. The daily intake of Cr estimated in this work was under than that reported in literature, which ranges between 0.013 and 0.098 In humans, it helps in the production of blood haemoglobin.…”
