Acute health effects common during graffiti removal

Area of Science:

• Occupational Health
• Environmental Health
• Toxicology

Background:

• Graffiti removal utilizes various cleaning agents, primarily organic solvents.
• Worker exposure to these chemicals is a potential occupational health concern.

Purpose of the Study:

• To identify potential health effects linked to different cleaning agents used in graffiti removal.
• To assess exposure levels and health outcomes in graffiti removal workers.

Main Methods:

• 38 graffiti removers in Stockholm underwent air sampling, biological monitoring, interviews, and questionnaires.
• Health effects were evaluated through physical examinations, spirometry, and questionnaires.
• Symptom prevalence was compared to depot and population controls.

Main Results:

• Average organic solvent exposure was below 20% of the Swedish permissible exposure limit (PEL).
• Short-term exposures occasionally exceeded short-term exposure limit values (STEL), particularly in poorly ventilated areas.
• Graffiti removers reported significantly higher rates of fatigue, headaches, and irritative symptoms (airways, eyes, skin) compared to controls.
• Seven workers showed a reduction in peak expiratory flow (PEF) during their work shift.

Conclusions:

• Despite low average exposure, graffiti removers experienced increased non-specific and irritative symptoms.
• Informing workers about health risks and restricting hazardous chemical use are essential.
• Developing good working practices and promoting personal protective equipment (PPE) are recommended.
