Investigation of symptoms and lung functions in tea packaging factory employees

Abstract

Inhalation of organic powders may lead to various diseases such as asthma-like syndrome and hypersensitivity pneumonia. The study aim to evaluate respiratory health effects by respiratory function measurements, respiratory survey, ambient dust concentration, and toxic gas in workers of a tea packaging factory. 69 employees from different departments of the tea packaging factory were included. A group of 53 office workers of a separate establishment was included as a control. Sputum production in the morning was significantly higher in the tea packaging workers (p=0.013). Among the respiratory function values, only FEV1/FVC was lower in this group than in the control group. There was a significant decrease in FEF75% value among smokers in the study group compared to non-smokers. Respiratory effects observed in some food processing industry workers are also seen in the tea packaging industry. Effective dust control will positively affect the health of the workers. More studies are needed to better identify potential risks.
