Cotton dust sampling: I. Short termed sampling.

Abstract

A short term sampler for cotton dust is introduced which, when used in conjunction with a correctly designed vertical elutriator, gives equivalent results to the Lumsden-Lynch vertical elutriator. The short termed sampler not only offers results which can be applied to the ACGIH TLV but offers an effective means of environmental surveillance in a byssinosis prevention program with the additional advantages of immediate read-out short termed sampling and truer employee exposure.

Prevalence of byssinosis and other respiratory problems among textile mill workers in Asaba, Nigeria.

OBJECTIVES: This study was conducted to determine the distribution and severity of byssinosis and other respiratory problems in the different operation sections in a textile mill industry in Asaba. PATIENTS AND METHODS: This is a cross-sectional and analytic study in which workers directly exposed to cotton dust are compared with those not directly exposed to cotton dust at one point in time. RESULTS: A total of 735 workers were interviewed and 437 workers had respiratory examinations carried out on them. Byssinosis was diagnosed in 8 out of 405 workers (prevalence of 1.98%) who were not directly exposed to cotton dust, and 21 out of 330 workers (prevalence of 6.36%) who were directly exposed to cotton dust. The difference was found to be statistically significant (chi2 =9.25; df=1; 0.01<p<0.001). The spinning department had the highest prevalence of 11.5%. The prevalence of respiratory abnormalities which did not necessarily meet the criteria for a diagnosis of byssinosis was 4.9% for persistent cough and persistent phlegm; 8.0% for dyspnoea grade 2+; 3.3% for dyspnoea grade 4 and 2.59% for dyspnoea grade 5. Smoking was not found to be associated with the disease as none of the byssinotics were current smokers CONCLUSION: Byssinosis and other respiratory problems were found to be more prevalent in sections of the textile mill industry that were directly exposed to cotton dust. These findings form a basis for making suitable recommendations for the prevention of byssinosis and respiratory diseases in textile mills in Nigeria.

A 20-year follow-up study on chronic respiratory effects of exposure to cotton dust.

In order to evaluate chronic effects of long-term exposure to cotton dust on respiratory health, and the role of dust and endotoxin, longitudinal changes in lung function and respiratory symptoms were observed prospectively from 1981 to 2001 in 447 cotton textile workers, along with 472 silk textile controls. The results from five surveys conducted over the 20-yr period are reported, including standardised questionnaires, pre- and post-shift spirometric measurements, work-area inhalable dust sample collections and airborne Gram-bacterial endotoxin analysis. Cotton workers had more persistent respiratory symptoms and greater annual declines in forced expiratory volume in one second (FEV1) and forced vital capacity as compared with silk workers. After exposure cessation, in the final 5-yr period, the rate of FEV1 decline tended to slow in nonsmoking males, but not in nonsmoking females. Workers who reported byssinotic symptoms more persistently suffered greater declines in FEV1. Chronic loss in lung function was more strongly associated with exposure to endotoxin than to dust. In conclusion, the current study suggests that long-term exposure to cotton dust, in which airborne endotoxin appears to play an important role, results in substantial adverse chronic respiratory effects.
