ABSTRACT
The dissolved heavy metals (Cu. Fe. Cd. Zn and pb)in water of
lake Bumllos Were estimated in three sectors from the lake during the
period/rom March 1997 Till March 1998.
The average mlues (ug 1)/or the 1l’hole Lake were 3.52. 2.46.
1. 93. 6.76 and 2. 67 ,Ltg I/oI’ Cu. Fe. Cd. Zn and ph respectively.
Results indicate that. levels of heavy metals decreased In a
westward direction and are correlated \I’ith Salinity changes due to
the discharge ojwater.
