Determinación electroquímica de plumbemia en niños residentes en la Ciudad de Córdoba, Argentina

With the purpose of evaluating the incidence of environmental factors in the intoxication for lead in the infantile population, blood samples from 92 children which attended the Hospital Municipal Infantil of the City of Córdoba were studied. The lead concentration in blood was determined by means o...
