Epidemiological study of gastrointestinal and liver effects of carbon disulfide.
In the framework of an extensive health survey, 119 viscose rayon workers exposed to carbon disulfide (CS2) and 79 workers from other plants not exposed to any toxic agent in the working environment underwent a gastrointestinal examination including a self-administered questionnaire, abdominal palpation, percussion and a number of liver function tests. In the viscose rayon factory the working conditions have not changed since 1932. Personal monitoring performed in 17 jobs showed CS2 exposures varying from 4 to 112 mg.m-3. For each individual a cumulative CS2 exposure index (CS2 index) was calculated. Univariate analysis of the questionnaire findings showed significantly higher prevalences of anorexia (37.0% vs 11.4%, P less than 0.0001), vomiting (12.6% vs 3.8%, P = 0.04), and recent weight loss (10.9% vs 1.3%, P = 0.009) in the exposed than in the non-exposed workers. The exposed workers had a larger total number of gastrointestinal complaints and a larger proportion reported at least one complaint at least once a month than the non-exposed ones. Abdominal tenderness was very rare in both groups. In multiple logistic regression analysis, adjusting for alcohol intake, smoking, body mass index (BMI), coffee consumption, commuting time, stress at work, shift work, educational level, family history of ulcer disease and intake of medication, significant associations with exposure were found for anorexia (P = 0.0001), nausea (P = 0.009), vomiting (P = 0.002) and flatulence (P = 0.03). Stress at work was a determinant for quite a few digestive complaints, but shift work was not significantly associated with any of them.(ABSTRACT TRUNCATED AT 250 WORDS)
