Heavy metals such as cadmium, lead, iron and zinc were investigated in soil and lettuce obtained from irrigated farmlands of Kaduna metropolis. Concentrations of heavy metals were determined using atomic absorption spectrophotometer. The results obtained were compared with limit recommended by FAO/WHO standard (2007) so as to ascertain the extent of their pollution. The level of cadmium in cabbage ranged from 0.04-1.20μg/g. The concentrations of lead was found to be in range of 0.61-3.87 μg/g ,these were above the limit stipulated by WHO while iron concentration ranged from 0.50-12.40μg/g and zinc 2.72:g/g-18.53μg/g were within the recommended limit given by the FAO/WHO standard. This suggests that consumers of cabbage grown in the studied areas might be liable to lead and cadmium toxicity as at the time of this research work. Pearson correlation shows positive correlation between soil and cabbage in these irrigation sites.
