The levels of minor metals : Sn,Mn,Zn, Cu,Cr,Cd,Pb,Fe,As,TiAl and major metals; Na, K, Ca and Mg were determined in the paint effluent, metal dump site and the associated leaves of Nicotiana tabacum plant from a Crown caps industry. Levels of Al, Mg, Na, K,, As, Cr, Cd, Ti an Ca were all correspondingly higher in the N. tabacum leaves than the soil, this could be dut to the metal bioaccumulation of the metal in the leaves. With the exception of As (with 231.5 ppm) all the values oin the plant and dump site were higher than the values in the paint effluent. The correlation coeficient between the metal dump and tobacco leaves was significatnly, high (rxy = 0.68) with a low index of forecasting efficeincy (26.7%). Since all the samples were high metal determined (particularly) the trace metals) the industrial enviornment was polluted and would need constant monitoring.
