Ventilatory function in workers exposed to tea and wood dust.
Changes in ventilatory capacity during the work shift were studied in workers exposed to tea dust in tea-packing plants, wood dust in two furniture factories, and virtually no dust in an inoperational power station. The FEV1 and FVC in workers exposed to dust were found to decline during the work shift by a small but significant volume. The MMFR, Vmax 50% and Vmax 75% were to variable to displa...
متن کاملPulmonary function and symptoms in workers exposed to wood dust.
BACKGROUND Exposure to wood dust can cause a variety of lung problems, including chronic airflow obstruction. METHODS Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory ratio (FEV1/FVC x 100), forced expiratory flow (FEF), forced mid expiratory flow (FMF), peak expiratory flow (PEF), and respiratory symptoms (cough, phlegm, breathlessness, wheezing, ...
متن کاملChronic Respiratory Symptoms and Ventilatory Function in Workers Exposed to Tea Dust: Effect of Duration of Exposure and Smoking
Many studies reviewed show that both workplace exposure to organic dust and smoking may cause chronic respiratory symptoms and airflow limitation in susceptible subjects. We performed a case-control study including 63 tea workers (36 male and 27 female, aged 36-55, duration of employment 3–30 years) and an equal number of office workers, matched by sex and age. Chronic respiratory symptoms (chr...
متن کاملWork-related symptoms among workers exposed to black tea dust.
BACKGROUND Tea may be classified as unfermented green, semi-ferinented oolong and fermented black. All of these types are derived from Camellia sinensis, the Tea Plant, which contains the low molecular weight (LMW) agent Epigallocatechin gallate (EGCg), probably responsible for allergic reactions. The aim of our study was to asses the work-related allergic symptoms and IgE-mediated sensitivity ...
متن کاملLung function in workers exposed to polyvinyl chloride dust.
Several reported studies on the effects of polyvinyl chloride (PVC) dust in animals and man have been conflicting. The present study of the ventilatory function of 509 male workers exposed to PVC dust was made in 1977. Altogether 104 men exposed to PVC dust only, 112 men exposed to non-chlorinated solvents only, and 293 men exposed to a mixture of both completed the MRC questionnaire on respira...
