March. % 1949 Sr* H* G* Dyktor, CoimaissiGner Division of Air Pollution Control 1404 East Math Street Cleveland 14* Ohio Dear Mr. Doctors In general I an in accord with your draft of the report of the American Medina! Association Committee on Atmospheric Pollution. However, there are a few changes that I would suggest. I have in my notes the statement: "Health hazards need not be demon strated to establish the mad for air pollution control", which I believe we agreed upon in Chicago. I suggest that it be added as a second sentence in Paragraph 4. It is ay impression that -m need not stress to the extant of paragraph ? the need for procedures for sampling and assessment of dustfall, aerosols and &s in the atmosphere. 1 as reasonably well satisfied with the techniques -that are already available* Specifically we are using the modified Cascade impa pastor, the electrostatic precipitator, the freeze-out train, the thermal settling chaatber* and the electronic microscope in the investigation of air pollution. Par igraph 8 to my way of thinking expresses the situation very effectively. I surest that paragraph 7 be deleted. / Isn't there a typographical error in paragraph 12? The statement is aa&e that an air pollution control program should H------- apprise the community of the fact that elimination of air pollution is economically impracticable.8 In paragraph 1 we say "Air pollution means the excessive concentration of foreign matter in the atmosphere which my adversely affect the well-being of the individ..m or cause damage to property.8 % reaction is that if we define air pollution as the excessive concentration of foreign matter, that we should not say that it is econoBically Inpracticable to eliminate it* I feel that if this statement were released to the nubile the reaction would be that we are saying that noting be done which would be a most unfortunate impression to leave. It is certainly desirable that municipalities should "eschew political considerations" as you suggest in paragraph 13 but I worrier, this being an Imper fect world, whether they will'do so. Perhaps it is all right to set it as a goal to be attained. Hr. K, G. Dyktor, Ckanaisaioner Division of Air Pollution Control -2- March Bs 1949 T5r. ft. f. Johnstons told as this coming on the telephone that he plants to further define the medical position. I -rrould like to see us encourage some serious research into this question of the physiological effect of air pollution. Such work by reputable medical foundation or the United States Public Health Service vmuld remove a great deal of confusion and backbiting, lie country can well afford to support such uork and I believe it would be a credit to the American Medical Association to sponsor it. I am enclosing a copy of the program of the American Chemical Society Symposium on Atmospheric fontaalnation and Purification which will coae off in San Francisco on March 2fi and 29. I urge yon to attend if it is at all possible I have had-letters indicating that Great Britain and South Africa will send a representative* I again extend my sympathies for your recent bereavement and I hope that the duties of your office have hot been overburdensOa as a result* Sincerely yours, LGItLS Sac. 1 cc Each member of Committee Louis C.
