Lao Yates Fomily Lifa Specialist Cooperative Extarnion Sarvica Clamton University Clemson, South Caroline 29631 5f I Dear Mr. Yates: i Wa Hove your recant circular latter requesting answers to a list of questions on the subject of "Lead Paint Poisoning of Children". Our answers to these questions ere as follows: - Question f 1: Do children become poisoned by liquid or dried point or both? * ^ * Answer: Lead is a cumulative poison. Lead poisoning results horn continued ingestion of leod. For this reason, it is likely that any lead poisoning related to paint develops from eat ing dried paint chips, i have never heard of a case of \ leod poisoning which developed from the ingestion of a ** /#| liquid point. -Q--u--e--s-t-i-o--n---f--1- - I* llteatfd based paint poisonou--s --thro- ugh giving off fumes?: How volatile Answer: At normal temperatures the fumes or vapors given off by leod based paints contain no leod end ere no more danger ous than the vapors given off by another paint which contains the soma volatile solvents. In other words, the matter of toxicity involved in breathing point vapors depends not on L . -- - r.->e lead content o ^t ,,pon the composition of the volatile I solvents and the concentration of the vapors. There is no -;sed fume" problem with point. -- I tt- 1. r I Mosrtss THROUGH COOPERATION jr. 0007-SWP-000005719 i* i N te. f 1 I 2.

Pico, me craving of some children for unnatural food (paint and wood chips, for example)!* probably related to a nutritional deficiency. Question F 4 : Does poisoning come from inhalation, touch,or ingestion of the lead based paint? Answer: To our knowledge, leed poisoning cs it relates to paint is caused only by ingestion of dried paint chips which contain leed. Question * 5 : What ere some rources of studies done on characteristics common to cases cf poisoning of children by lead based point? Answer; ror information on studies of characteristics common to cases of poisoning of children by leed based pcinis, I would suggest contacting the Public Health Deportments of large cities. The Leed Industries Association, 292 Madison Avenue, New York City, can also be helpful in providing this type information. Question F 6 : What ore the symptoms exhibited by a child poisoned by a lead based ________ pqfoyfr ........ Answer: it is our understanding that typical symptoms are: 1) Pains in the stomach . 2) Frequent vomiting 3) Crossness end irritation without a visible reason 4) Many headaches 5) Muscle weakness end constant tiredness 6) Spasms 0007-SWP-000005720 ________________ - --* * ` ' r-;-' 3.

It it very important, however, to hove a chi id,.suspected of eating point chips, examined at once by a doctor. Quettion $ 8: Whot points generally use ieod os a bote? by function, by type - Answer: At stated earlier, lead is rcrely used in modern interior paints. There it no longer any purpose in using lead pigments in paints intended for interior use since better lead-free pigments for this purpose are available at lower cost. Lead pigments are used today in structural steel primers, in tome exterior house paints, and other exterior coatings. Lead pigments are relatively expen sive end their use is generally confined to providing rust-inhibitive properties on steel surfaces and for good exterior durability in certain exterior wood and metal paints. . I om enclosing a copy of a publication entitled, "How to Prevent Lead Poisoning in the Home*1*. This booklet was published several years ago end is now out of print. We 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 end furniture which you may find of interest. We would certainly appreciate having you send us a summary of the'findings you develop from your questionnaire. ' Sincerely yours. RAB/fms Enclosures Technical Director 0007-SWP-000005721
