Lso Yates Family Life Spacialist Cooperative Extension Service Ciomson University Ciemson, South Carolina 29631 Dear Mr. Yates: i We hove yowr recent circular letter requesting answers to a list of questions on the subject of "Lead Paint Poisoning of Children". Our answers to these questions are as fellows: Question * 1: Do children become poisoned by liquid or dried paint or both? Answer: Lead is a cumulative poison. Lead poisoning results from continued ingestion of lead. For this reason, St is likely that any lead poisoning related to paint develops from eat ing dried paint chips. I have never heard of a cose of lead poisoning which developed from the ingestion of a liquid paint. \ -Q--u-e-s--ti-o-n---f--2-- uI* jlteatfd based paint poisonou"s"t"h"ro' ugh giving off fumes?: How volatile Answer: At normal temperatures the femes or vapors given off by lead based paints contain no lead and are no more danger ous than the vapors given off by another paint which contains the same volatile solvents . In other words, the matter of toxicity Involved in breathing paint vapors depends net on - we lead content b^r ,,pon the composition of the volatile solvents and the concentration of the vapors. There is no "iecd feme" problem with paint. f*ft` * MOOMItt THROUGH COOPERATION Js 0007-SWP-0000057X9 2.

Interior points hove r.ot csnroir.es white ieed pigments hr opproximerely thirty ytors. The greatest danger, therefore, occurs in old tenement dwellings which heve wails that were painted 25 to 30 yean ego, and which . ..have not been maintained properly. Picq, me craving of some children for unnatural food (point and wood chips, for example)is probably related to a nutritional deficiency. Question * 4 : Does poisoning come from inhalation, touch,or ingestion of the lead based paint? Answer; To our knowledge, lead poisoning as it relates to paint is caused only by ingestion of dried point chips which contain lead. Question * 5 : Whot are some sources of studies done on characteristics common to cases of poisoning of children by leod based point^ Answer; rot information on studies of characteristics common to coses of poisoning of children by Ieed based points, I would suggest contacting the Public Health Deportments of lotge cities. The Lead Industries Association, 292 Modison Avenue, New York City, can also be helpful in providing this type information.

It is very important, however, to have a chiId,suspected of eating paint chips, examined at once by a doctor. Question i 8: What points generally use lead os p base? by function, by type - Answer: As stated earlier, lead it rerely used in modem interior paints. There is no longer any purpose; in using lead pigments in paints intanded for interior us* since better lead-ire* pigments for this purpose are available at lower cost. Lead pigments are used today in structural steel primers, in soma exterior house paints, and other exterior coatings. Load pigments are relatively expen sive end their us* is generally confined to providing rust-inhibitive properties on steel surfaces and for good exterior durability in certain exterior wood end metal paints. I am enclosing a copy of a publication entitled, "How to Prevent Lead Poisoning in the Home". This booklet was published several years ego end is now out of print. W* ere in the process of revising the subject matter and expect to publish a new booklet on this subject in the near future. I am also enclosing a copy of our booklet directed to the painting of childrens' toys and furniture which you may find of interest. W* would certainly appreciate having you send us a summory of the'findings you develop from your questionnaire. Sincerely yours. RAB/fms Enclosures Technical Director I .. -I . 0007-SWP-000005721
