QUESTION:
Lead poisoning from Samovars, 30 Mar 2006,
Brussels Belgium
I am a lead specialist since about 30 years, I know, for example, Prof Gulson, Nriagu, Patterson (+). I have made a thesis on lead isotopes in the environment in 1977 and published already an article in EPSL on this subject in 1974. I am very surprised that we do not mention the lead source coming from traditional teapots . I have published in 2003 an article in Grenoble (conference on heavy metals in the environment) which speak about this heavy contamination. At this moment only one article speaking about the dangers of traditional metallic teapots about ten years ago (teapots and toxicity project, to be published, but unfortunately never found). These teapots were largely used among Moroccans coming from immigration (and also in tea "salons"). The result are dramatically high a lead concentration of about 400 ppb is commonly found in tea brewed with these teapots there is an increased lead leaching influence due to copper coming from tea and the teapot itself). Perhaps this source is of minor importance in your country ? If you are interested I could give you additional information and comments about my study which is still continued in Brussels.
