Fish and water resources that promoted as natural sources that free of contaminant, were selected from three states (Khartoum, Nahr elnile and Sinnar). Water and Fish samples were assayed for Lead, Cadmium, Mercury, Arsenic, Zink and Copper. Fish samples showed low levels of Zinc, Cadmium and Copper compared to the standard acceptable levels, while lead showed a significant high level compared to the standard acceptable level. Zinc and copper levels in water samples were significantly lower than the standard acceptable levels, while cadmium level was higher at Gabal awalia dam area (Khartoum state). Mercury and arsenic showed high and low levels respectively compared to standard levels. All water samples recorded significant high level of lead compared to the standard acceptable level.
