IODINE-AZIDE TEST ON URINE OF PERSONS EXPOSED TO CARBON DISULPHIDE

Abstract

The iodine-azide test was performed on the urine of workers exposed to carbon disulphide in a viscose factory. The exposure coefficient was determined before, during, and after the working time, and showed a good correlation with the exposure. Workers exposed to a high concentration of carbon disulphide could be divided in two groups. The first group showed normal values of the exposure coefficient before work but low values at the end. (The coefficient is inversely related to the exposure.) In the second group, the workers started work with slightly decreased values and ended with greatly decreased ones. We are pursuing this study to establish why recovery in the second group was not complete.
