The Paint samples were gotten from old houses in areas of Ikorodu, Onipan, Lekki, Berger, Agbado-Ijaye, Lagos Island, Moremi and Makama hall (University of Lagos) and were digested using three different methods, which include

1) Nitric acid and per-chloric acid digestion

2) Nitric acid and hydrogen peroxide digestion

3) Dry ashing digestion using muffle furnace

    These methods were compared and was discovered that oil - based paints (gloss paints) has higher concentration of lead than water - based paints (emulsion paints).

    Lead is a very poisonous metal and should not be used in paints because of its harmful effect on human lives.
