Changes in the local environment have been monitored for chemical pollution in the past. Maracaibo Lake is one of the most important water basing and oil producing regions in Venezuela. Radioisotope Concentration in Lake Sediments of Maracaibo, Venezuela At this moment, there is not definitive proofs that vanadium compounds are the etiological agents of the Neural Tube Defects, but, these compounds are presents in foods produced in the northeastern coast of Lake Maracaibo. The amounts of vanadium in the different foods analized were higher than the controls in the bibliographic reports. The digestion of the samples achieved by the methodology reported by Myron et al., with Graphite Furnace Atomic Absorption. Lagunillas, Valmore Rodriguez, and Baralt were the districts selected for the work. The main goal of this work is to measure the vanadium content in foods produced in the northeastern coast of Lake Maracaibo. In fact, some experimental works inform about the vanadium compounds cellular toxic effects mainly in the Central Nervous System of mammals. This epidemiological problem is present in other countries too (Ireland and New Zealand) and has been associated with oil activities. In the northeastern coast of Lake Maracaibo it has been reported some years ago a high incidence of congenital malformations of the Central Nervous Systems (Neural Tube Defects Type).
