It does seen appropriate for you to bare determined tha proper order of magnitude of toxicity to that suitable handling precautions aa have been developed for both types of ctaqtouada could be applied. X vould suggest, therefore, that consideration be given to determining toxicity by oral aad percutaneous routes for nil cenpotods, aad that of toxicity follow ing Inhalation by ccapouada which aay have a elgnlfleant vapor pressure. At thin stage only order of nagaltude figures need be obtained, aad ve propose to use our nodlflcatlcn of the standard method of Celcbaaan, la tdklch tha aad LDj q voild be bracketed by adalnletratloo of tbs compounds over a range of doses or concentrations. At such tine as further Infcreation U needed concerning the ccnpouod.

Ve are appending our recommendations for aoecapllahlag this preliminary toxicity evaluation and tha coats relative to these. Ve should like to point out that our laboratory baa bad considerable experience la the - of dangerous and highly toxic compounds, including explosive materials, sad that cur staff, therefore, le Competent to handle compounds of any degree of toxicity end potestlei baiard.

What la at Issue is the aaowt of leed uhlch can leech fron piping Mmo It la used for potable ester supplies. Bines the use of rigid P.V.C. p'pe has a food future potential as a replacement for metallic pips. It will be wU for us to measure the leed release or leecbshlllty from the pipe Mmo It la used la standard household water supply systems. Producers of P.V.C. pipe appeer to hesitate to use lead as a stabiliser becsuse of the possibility of such pips beInc Inadvertantly used la a water eupply system. If, however, ws could reessure the plastics industry with ipproprlate measurements at lead leachabUlty (asaiming that tha lead release la low enou>) then sueh producere would feel free to use theaa hltfily desirable lead compounds. ecopt da purpose of this proposedprogram la to obtain lead release data from standard formulations of rigid P.V.C. piping In order to promote tha use of such leed stabinters In the industry. Cm program will be carried cm la two cooeecvtlve phases, the first at Milch will stealns la preliminary fashion vbetber or not excessive anoucts of lead will be released frea standard -3 piping system. If tha lead release is satisfactorily lew than tha second * phase of the program will be carried co Milch will involve obtaining testa and approval at such piping systems for use la potable water supplies. Of oourse, if tha first phase at the pragma shows that ws are not la the rlfit ball park and that lead leaches fits the piping systasM la esceaslva aaotete, we Mil go no further. Bo c bc w c THcrrrvrt Ki&ld vinyl pipe la presently being pradueed la the aaost f about 80,000,000 pounds per year of Milch only 2011 la presently stabHired with leed cavounds. Ve estimate that this provides a market at not mors than 80 tons at lead per year at the present tine. If all of the rigid P.V.C. pipe were etehlllsed with lead compounds, the present market would be att MO tens of leed per year, gcwtvtr, this Is a rapidly expanding market and tha future potential looks good, sueh that la 1967 It la estimated that 100,000,000 pounds of rigid P.V.C. pipe will be produced. Therefore, the present situation Is of ltts Importance to us than tha future and, since It will taka sema time to oarry on a tasting sad approval program, and since the ratultc of the testing and approval program should ha available before the reel aarkat potential tea be realised, it would be Inombent upon us to carry out such a program.
