The blood lead measurement in pottery-glaze workers was carried out by graphite furnace atomic absorption spectrometry (GFAAS) and the LCS. this last method was also used in the general population. The food lead level was quantified through GFAAS. The paired data showed a significant correlation (r = 0.976, p < 0.001), a mean difference of 3.3 µg/dL with limits of agreement between - 2.4 to 9 and an intraclass correlation coefficient of 0.928. These results indicate a good concordance between both methods. The blood lead median of 32.0 µg/dL and interquartile range (IQR) of 16.1 was higher in the pottery-glaze workers than in the general population (children = 5.4 µg/dL, IQR = 5.9 and adults = 8.3 µg/dL, IQR = 2.7). Lead in food exceeded the maximum level considered in the Codex alimentarius. Pottery persists as a potential risk in the Tlaxcala State population. 2017 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37050971005 https://www.redalyc.org/journal/370/37050971005/ https://www.redalyc.org/journal/370/37050971005/html/ https://www.redalyc.org/journal/370/37050971005/37050971005.epub https://www.redalyc.org/journal/370/37050971005/movil 10.20937/RICA.2017.33.01.05 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.1 Vol.33 |
