“Photocopier operators reported significantly higher incidence of nasal blockage (p = 0.003) and breathing troubles (p = 0.03).”

Chronic exposure to emissions from photocopiers in copy shops causes oxidative stress and systematic inflammation among photocopier operators in India (2013). Environmental health : a global access science source. Page 5. CKB 6861

Structure

Source: Printers and photocopiers
Outcome: Respiratory symptoms
Population: photocopier operators
Setting: copy centre
Study design: cross-sectional study of photocopier operators in copy centres against a control group: respiratory symptoms, general health problems and lung function compared between the groups (class 4)
Caveat: self-reported symptoms; the study also finds excessive sputum production more common at p = 0.004
