| contents | Cadmium and lead levels in deciduous teeth of children living in México City Juan Carlos Hernández Rocío García Raúl Belmont Armando Báez Ciencias de la Tierra teeth México children cadmium and lead exposure teeth cadmium and lead concentrations Cadmium and lead levels in 79 deciduous teeth from children between 5 and 13 years old livingin the México City Metropolitan Zone were determined by graphite furnace atomic absorptionspectrometry. Lead and cadmium concentrations showed a positively skewed distribution andresults were transformed into logarithms. The geometric mean concentrations (GM) in all teethwere 0.22 ± 3.4 and 10.2 ± 2.2 µg g-1 for cadmium and lead, respectively. No statistical differenceswere observed for cadmium and lead concentrations among tooth type, tooth position,gender, socioeconomic level, and use or no use of color crayons. Cadmium values decreasedwith childrens age and lead levels did not show a clear tendency. Statistical differences wereonly observed for cadmium according to age. 2004 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37020303 en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.3 Vol.20 |
