Summary
Treasury workers exposed to dirty currency notes experienced impaired lung function, particularly males. This study highlights potential respiratory risks associated with handling contaminated money.
Area of Science:
- Occupational Health
- Pulmonary Medicine
- Environmental Health
Background:
- Treasury workers handle large volumes of currency, potentially leading to exposure to contaminants.
- Previous studies have not extensively investigated the respiratory effects of prolonged currency note exposure.
Purpose of the Study:
- To assess the impact of chronic exposure to old and dirty currency notes on the lung function of treasury workers.
- To identify potential ventilatory defects in this occupational group.
Main Methods:
- Lung function tests (spirometry) were conducted on 72 treasury workers and compared to a control group.
- Participants were assessed for forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and peak expiratory flow rate (PEFR).
Main Results:
- Male treasury workers showed significantly lower FVC, FEV1, and PEFR compared to controls.
- Female workers' lung function values did not significantly differ from their matched controls.
- The observed reductions in male workers suggest a restrictive ventilatory defect.
Conclusions:
- Chronic exposure to currency notes, especially old and dirty ones, may negatively impact lung function in treasury workers.
- Occupational health strategies should consider the respiratory risks associated with handling currency.
