Mineral elements are elements in form of minerals salts required by plants for normal growth and development and their deficiency can easily manifest on plants. Twenty (20) different samples of plant tissue from Yankaba and Janguza mar-kets of Kano State were analyzed for the level of Cu, Fe, Zn, Mn, Ca, Mg, K and Na. These elements are grouped into heavy metal (Cu, Fe, Zn, Mn) and light metals (Ca, Mg, K, Na) that affect the well being of plants and animals at high concentrations. Based on persistent nature and cumulative behaviour of these elements, there is need to test and analyze food items to ensure that the level of these elements meet international stanard. This is particularly important for farmers in West Africa where only limited data are available. The level of Cu, Fe, Mg, Zn,Ca and Mn were determined by atomic absorption spectroscopy while that of K and Na were determined by flame photometric method. Samples from Yankaba market indicated highest mean levels of Cu (0.100mg/g), Fe (0.230mg/g), Zn (0.088mg/g), Mn (0.085m/g), Ca (2.661mg/g), Mg (1.660mg/g), K (1.06mg/g) and Na (2.302mg/g). While those from Janguza market indicated highest lev-els of Cu (0.820mg/g), Fe (0.082mg/g), Zn (0.044mg/g), Mn (0.040mg/g), Ca (1.725mg/g), Mg (0.467mg/g), K (0.286mg/g) and Na (1.385mg/g). Comparison of the results obtained from the two markets showed that the mean concentration of the mineral elements of plants tissues obtained from Yankaba markets were generally lower than that of Janguza market.
