“…Only 7% of the mothers reported using glazed pottery to cook or serve food, and it was more common among the families of children with B-Pb within the permissible limits. This suggests that better-quality glazed pottery were being used [25], or that children were not eating from food served in pottery. As for passive smoking, the fact that 68% of the children were exposed may have reduced the power of detecting a significant difference.…”

“…Acra et coll. [13] ont montré que la concentration de plomb lessivable à l'acide acétique était en moyenne respectivement de 97,7 mg/L et de 3,8 mg/L pour les poteries artisanales et les poteries industrielles. L'essai de migration du plomb dans le second plat à tajine (37,8 mg/L), vendu comme une poterie artisanale, semble confirmer l'origine de celle-ci.…”

Intérêt de la mesure des isotopes du plomb dans un cas d’intoxication familiale par un plat à tajine

Résumé -Objectifs : Le dosage de la plombémie présente un intérêt majeur pour surveiller et mettre en évidence une exposition professionnelle ou environnementale à cet élément. Nous rapportons trois cas de saturnisme environnemental liés à l'usage d'une poterie artisanale, documentés par l'analyse du plomb dans les milieux biologiques, ainsi que dans un plat à tajine. La confirmation de la source de plomb est réalisée par la mesure de ses isotopes. Méthodes : Après consultation médicale, trois sujets de nationalité marocaine utilisant quotidiennement un plat à tajine ramené du Maroc en 2003 ont fait l'objet de divers prélèvements biologiques (sang, urines, phanères). Le dosage du plomb est réalisé dans le sang, les urines et les phanères par spectrométrie à plasma induit couplée à la spectrométrie de masse (ICP-MS.) Une optimisation des acquisitions est mise en oeuvre pour la mesure des isotopes du plomb ( 206 Pb, 207 Pb, 208 Pb). Le plomb est également quantifié dans une solution d'acide acétique à 4 %, après 24 heures de contact dans le plat à tajine à une température de 22• C selon la directive européenne relative aux ustensiles de cuisson en céramique de catégorie 3 en contact avec les aliments. Résultats : Pour les trois sujets (le père, la mère, le fils), les plombémies sont comprises entre 168 et 296 µg/L (témoins < 63 µg/L) et les plomburies entre 20,0 et 22,7 µg/g de créatinine (témoins < 2,1 µg/g). Les dosages dans les ongles de pied révèlent des concentrations s'échelonnant entre 3,8 et 34,0 ng/mg (témoins < 1,8 ng/mg) ; alors que les teneurs capillaires varient de 1,2 à 27,5 ng/mg (témoins < 4,6 ng/mg). La concentration en plomb de la solution acétique à 4 % est de 13 680 mg/L (norme < 1,5 mg/L). L'analyse graphique des rapports isotopiques du plomb montre une forte convergence entre les ratios isotopiques de la solution acétique et ceux obtenus chez les trois sujets. Conclusions : Le dosage du plomb dans les milieux biologiques par ICP-MS constitue la méthode de choix pour mettre en évidence une intoxication par cet élément. De plus, l'analyse isotopique permet de préciser l'origine du métal. Outre l'exposition professionnelle, les sources environnementales de plomb pouvant être multiples, il convient de mener une enquête, sans oublier les causes plus rares constituées par les poteries artisanales à glaçure plombifère destinées à stocker des boissons ou utilisées pour la cuisine.

We report three environmental cases of lead poisoning due to the use of traditional earthenware for cooking. Lead was assessed in biological matrices and in the traditional earthenware. Lead isotope measurement was consistent with contamination by traditional earthenware. Methods: Three Moroccans daily using traditional earthenware brought from Morocco in 2003 were taken samples of blood, urine, hair and nails. Lead was determined in biological ma...

“…Lead glazing is still used today. Such pottery sufficiently contaminates food and liquids to represent a significant health hazard, especially in some ethnic groups and regional distribution networks [7][8][9][10][11][12][13][14][15][16][17]. Much of the problem in recent decades comes from everyday pottery made for relatively limited and poorly regulated markets; therefore, this sort of Pb-exposure has an uneven geographical distribution.…”

Release of lead from Renaissance lead-glazed ceramics from southern Denmark and northern Germany: implications from acetic acid etching experiments

et al. 2022

Lead-glazed potsherds from archaeological excavations at six Renaissance (1536–1660 CE) sites in southern Denmark and northern Germany have been subjected to etching experiments using 4 wt% acetic acid. The extracts of 45 sherds were analysed by Inductively Coupled Plasma Mass Spectrometry. At one site, the ducal hunting castle of Grøngaard, Pb levels in acid extracts from glazed dishes were so high (up to 29,000 µg Pb cm−2 day−1) that acute toxic effects likely occurred if the dishes were used for serving food containing vinegar. More moderate acid-etching Pb levels were found in dishes from other sites, but they still exceed the WHO critical level if used daily. Acetic acid etching experiments performed on pipkins (three-legged cooking pots with a handle) yielded somewhat lower Pb extract values, averaging ca. 25 µg Pb cm−2 day−1. Taking into account the widespread use of pipkins for cooking, they might easily have led to a higher weekly Pb intake than the use of the moderate-level dishes. The question remains whether such high levels of Pb exposure during meals led to injurious Pb intake. Prior skeletal analyses have shown that medieval to early modern individuals from the area, especially in towns, were exposed to Pb. While exposure could have come from various sources other than lead-glazed ceramics, such as cosmetics, paint, antibacterial ointments, and lead water pipes, widely distributed lead-glazed ceramics had the potential of being a main source of Pb. How the pottery was actually used is uncertain, and it certainly was not evenly distributed across all segments of society, but the etching experiment results suggest that severe poisonous effects could have resulted from the use of lead-glazed Renaissance ceramics.
