This paper is a follow-up on thirty-eight workers exposed from 1 to 24 years to average benzene concentrations generally between 5 and 50 ppm, but as high as 90 (peak of 140) in the case of one worker. One individual was diagnosed as suffering from m

A four-year longitudinal study of ventilatory function in polyurethane-foam production workers exposed to toluene diisocyanate (TDI) revealed a dose-response relationship between average exposure to TDI and change in forced expiratory volume per seco

Studies have been made of the vapor pressure of benzene in mixtures with various aliphatic hydrocarbons and a positive deviation from Raoult's Law was shown. Because of this the benzene vapor concentration resulting from the handling of such mixtures

Workers in a factory producing polyurethane foam have been studied at six-month intervals for a period of 18 months. On each of the four surveys the forced expiratory volume in one second (FEV1) was determined on Monday morning and afternoon. The con

Over twenty years’ experience with the specific gravity adjustment in urinalysis has been reviewed. It is concluded that this method of expressing results of analysis of urine for heavy metals, solvent metabolites, and radioactive isotopes is prefe

The measurement of 2,5-dichlorophenol in urine as a metabolic product of p-dichlorobenzene was studied in relation to its usefulness in industrial exposures to p-dichlorobenzene. The chlorinated phenol was steam-distilled from, acidified urine and de
