Resumen:
Research on the biological effects of vanadium in humans has shown that acute poisoning in workers can manifest itself in a number of symptoms. There are no reports in humans about reproductive and developmental effects induced by vanadium compounds in humans; however, some studies with rats and mice indicate that vanadium can cross the placental barrier and accumulate in fetal membranes rather than the fetus itself. In this case, probably most consequences of administration of vanadium to pregnant females like reabsorptions, fetal death and reduction in size can be the result of maternal toxicity. Concerning genetic and related effects in humans exposed to different vanadium compounds, data are controversial. Data on genotoxic effects in workers exposed to vanadium indicate that they can have an increased risk to develop cancer, and DNA instability can give rise to an onset of genetic syndromes, fetal malformations, and cancer. This paper presents materials presented at the 8th International Symposium on Vanadium Chemistry, Biological Chemistry, and Toxicology in a session titled 'Relationship between occupational and environmental exposure to vanadium compounds and the reprotoxic and genotoxic effects'. © 2014 Informa Healthcare USA, Inc.
