An attempt has been made to investigate occurrence and bioaccumulation of metallic elements in river Ganga water at Allahabad using laser induced breakdown spectroscopy technique. The recorded spectrum shows the presence of atomic lines of the micronutrients (Ti, Si, Cr, Co, Br, Ba, Sr), macronutrients (H, N, Na, O, K, Ca, Mg, Cl, C) and toxic metals (Hg, Pb, Cd).
