Rada Toksikol. 11(1), 35-44(1960). Hematological and urinological examn. of galena miners (ore contained PbS 2.54, ZnS 3.37, CuFeS 0.38, FeAsS 0.58, and FeSj 15.15%) indicated that the level of Pb in blood and urine was approx, the same as the level among people not exposed to mine dust, 40 y/\. The a Pb level was higher in inhabitants of a community living in the vicinity of the mine, 60-220 y/\. The possibility of Pb poison ing by dissoln. of PbS in gastric juices was demonstrated, but no clin. case of such poisoning was established. T. Jurecic Effects of hair lacquer sprays on the lungs. A.

The granular powder provoked a mild foreign-body reaction only, without fibrosis; this is attributable to atm. oxidn. of the surface since this powder is manufd. without lubricant. The lack of pathogenic difference between I and II coated stamped powders may be due to the action of body fluids in pulmonary tissue which apparently penetrat'. either coating upon prolonged contact.
