Waste water samples from three different industrial areas in Lagos state (Ikeja, Apapa and Victoria Island) spanning the dry and wet seasons, were analyzed for Pb, Cu, Cd, Mn and Fe using the atomic absorption spectroscopic method. The mean values of Fe were within the FMEnV and WHO limits used as standard while the mean values of Cd, Cu, Pb and Mn exceeded these limits indicating that these industries constitute source of pollution to the human lives and ecosystem in the areas involved. Utilization of improved method of treatment and frequent awareness to the compliance of the industries were recommended
