Recent observations lepurted by Bogovoski indicate that aeration . feaUced the carcinogenic potency of Esthon- ian shale oil and prompted the present inves) tigation of the carcinogenicity of blown petro leum asphalt. Four materials were applied twice weekly to the clipped necks of C57 blick mice from the NIH stock: (1) benzol . soluble extract from natural Trinidad asphalt; (2) crude oil; (3) asphalt with a penetration , of 150 to 200 (ASTM method), which is obtained by distillation from the crude oil the rear of the plant where they were burned in a 55-gallon drum. Lead fumes from this operation were observed entering the open plant windows, and a large puddle of lead was later found in the burned-out drum. A unique control system was evolved by inte grating the operation of the hood, the exhaust ventilation, and a gas-fired incinerator. The hood exhaust runs horizontally a short dist ance and has a conveyor belt on the bottom. The empty sacks are placed on the conveyor and fed into the incinerator. The incinerator flue acts as the exhaust duct for the hood. and is then heated and treated with a stream of blown air to give (4) a highly oxidized "blown" asphalt. The crude oil was applied directly to the animals, but slight acetone v.--1' dilutions of the other three materials were ' used. 1 he four materials tested proved to be J.William Sghreibeis Industrial Hygiene Engineer Industrial Hygiene Foundation 4400 Fifth Avenue Pittsburgh 13, Pennsylvania Piperidine--A Hazardous Chemical Kiioriearcinogenic or so weakly carcinogenic to On August 17, 1964, a chemical operator **h6- skin of C57 black mice that they did not engaged in transferring piperidine under any cancers within the normal life span room-temperature conditions received unex |jne species and strain.
