dc.descriptionFifteen workers from a rayon plant in Brazil were monitored. Air samples were taken during a mean period of 5.8 hours out of an 8 hour workshift, in three different adsorbing tubes. Five urine samples were taken at 4 hour interval from the beginning of the shift, and at the beginning of the next shift in which 2-thiothiazolidine-4-carboxylic acid (TTCA) concentration was analysed. Data from seventeen individuals were statistically studied, with the aim of establishing the best and the most practical sampling strategy of biological monitoring for workers occupationally exposed to CS2. For those chronically exposed to CS2, TWA air concentration lower than 30 and higher than 10 mg/m3, it was found that the higher the exposure levels, the lower was TTCA concentration in the end of shift urine samples. The results may be explained by dietary habits and/or by the small number of examined population or even eventual casualty. On the other hand they raise other hypothesis involving the chronicity of exposure which may lead to important changes in metabolism influencing the excretion rate of TTCA.
