The analysis of Lead (Pb), Iron (Fe), Chromium(Cr) and PH in walnuts were carried out in four different locations which includes Rumueme, Eliozu/Air Force, Oil mill and Aba road, the lead, iron and Chromium concentrations were analysed using atomic absorption spectrophotometer. (AAS) while the PH of the samples were analysed using a ph meter . the results obtained showed wide variations of concentrations of heavy metals present in these different locations as shown in tables 4.1, 4.2,4.3 and 4.4, the level of lead in the four different locations were high compared to the World Health Organisation’s recommendation which is about 0.005mg, this was actually attributed to the industrial activities taking place in these areas, and this may result to some health risks like cancer, asthma, hypertention,etc if the walnuts sold in these areas are excessively consumed, however, the PH result obtained for the four different locations were 6.20,6.50.5..30 and 6.40 respectively, this revealed that the cooked walnuts are quite acidic and may be due to the sources of water and other environmental factors.
