%X ni, v, cr, cd, cu and pb were determined in superficial sediment samples from system maracaibo lake. thirteen sampling points were sampled in tablazo bay, maracaibo strait and maracaibo lake, four times during 2 years as follows: october 1999 (rainy season), march 2000 (dry season), november 2000 (rainy season) and may 2001 (low rainy period). mean values (minimum-maximum) of heavy metals were: cu: 27,07 (2,31-75,46), cd: 3,37 (0,46-7,9), cr: 39,50 (3,98-98,28), pb: 60,59 (17,8-143,9), v: 50,44 (1,29-121,2) y ni: 65,31 (16,76-177,62) mg.kg-1. the metal concentrations present in sediments were in the following order: ni>pb>v>cr>cu>cd. metal concentration in sediments of maracaibo lake system, are similar to the aquatic systems with a high oil activity. samples showed a clear tendency to higher values in the eastern area of maracaibo lake and lower value in the western zone.
