As my project at the Center fer Science in the Public Interest, I am doing a study! ef lead in feeds, Although jrei,r interests seem to lie mere in the area ef atmospheric lead, I thought yea might be able te help me anyway. In yeur paper, ttUader What Circumstances is Ingestion ef Lead Dangerous?w,published in publication #1U1;0, Symposium n Environmental Lead, by the U. 3. Public Health Services in 1966, you mention that about 30y^g ef the lead ingested is retained in the human body. I would like to know how jmuch this lead comes from food rather than water, and how much of the lead in food comes from canning and packaging prcendures rather than household sources such as badly glazed pottery. I would appreciate receiving the answers te these questions if yeu have them, and alio any ether infematien yen could supply regarding lead in foods. Thank you. Sincerely yeurs. / (Miss) Nancy Stecker 0 017 0
