摘要: El mercurio genera afecciones nerviosas, comportamentales, renales, inmunes y sexuales, entre otras. personal que labora en la practica odontologica, expuesto cronicamente a vapores de mercurio, constituye una poblacion riesgo toxicologico. objetivo este trabajo fue determinar el contenido presente odontologico un hospital venezolano, con fin evaluar ocupacional. Para ello se colectaron muestras sangre orina del Unidad Odontologica, los dias lunes viernes cada semana durante cuatro semanas. determinado mediante Espectroscopia Absorcion Fluorescencia atomica vapor frio. Mediante analisis varianza probaron estadisticamente las hipotesis relacionadas similitud valores para diferentes grupos humanos analizados periodos muestreo. Los niveles analizado resultaron por debajo nivel umbral resenado Organizacion Mundial Salud 50 ?g/L (ppb) Hg. En sangre, 21% evaluada presento superiores al valor 15 Se encontraron diferencias significativas laborales. revela grupo esta toxicologico metal, recomendandose mas exhaustivos estas personas. ABSTRACT Mercury generates nervous, behavior, immune and sexual affections, among others. The personnel working in dentistry, exposed chronically mercury steam, constitutes population toxicological risk. objective of this work was to determine present dentistry Venezuelan hospital, for evaluating the occupational Blood urine samples were collected Unit Dentistry, days Monday Friday every week during four weeks. content determined by means spectroscopy absorption atomic fluorescence with cold steam. By variance analysis hypotheses related similarity values different analyzed human groups periods from sampling proven statistically. levels are underneath level threshold reviewed Health World Organization evaluated superior value ppb Hg blood samples. between labor significantly differences. reveals group is risk recommending more exhaustive analyses these people.
