Smoking generated PM 2.5 exposure among Transylvanian students

Area of Science:

• Public Health
• Environmental Health
• Medical Education

Background:

• A World Health Organization (WHO) project initiated in 2004 aims to reduce smoking among medical, dental, and pharmaceutical students.
• These students are future role models for patients, making their smoking habits a public health concern.
• Existing legislation on smoking in public institutions was contrasted with university-specific findings.

Purpose of the Study:

• To assess the general view of smoking and smoke exposure within a medical university.
• To compare air quality and smoking prevalence with non-medical universities.
• To evaluate compliance with and the effectiveness of smoking legislation in academic settings.

Main Methods:

• Air quality was measured using a TSI Pack Aerosol Monitor to determine PM 2.5 levels.
• Measurements were taken in various university locations during holiday and academic (didactic) periods.
• Statistical tests were employed to compare air quality data between different periods and locations.

Main Results:

• The university reported the most polluted air during the holiday period, with PM 2.5 levels of 0.016 mg/m³.
• PM 2.5 levels were significantly higher (p < 0.0001) during the didactic period compared to the holiday season.
• Airborne particulate matter readings were up to seven times higher in certain university locations during academic periods.

Conclusions:

• Smoking occurs within university buildings, contributing to indoor air pollution.
• Non-smoking students, particularly within the medical university, are exposed to exhaled cigarette smoke.
• The findings highlight the need for improved smoking control measures in universities to protect student health.
