Evaluation of the Relationship Between Outdoor Environment and Indoor Air Quality in Arid Condition

Abdulaziz B. Alharbi

Abstract:
Background and Objective: Several research studies have found a relationship between exposure to indoor particulates and serious health problems. In this research, the mass concentration of inhalable particles in four offices is measured experimentally. Materials and Methods: Three airborne particles sizes (PM1, PM2.5 and PM10), were monitored in the offices during occupancy and non-occupancy periods, Qassim University Campus, KSA. Results: The results show that most activities made in the investigated offices are a strong factor affecting PM10 and PM2.5. However, the influence of such activities on PM1 was not strong except for vacuuming where the concentration level increased during cleaning activity. The impact of outdoor particles on the air inside was significant for PM1 and PM2.5, while its effect on PM10 was moderate. Conclusion: Particulates generated outdoor contributed significantly to the particle concentrations in the offices, particularly for PM1 and PM2.5 size fractions. The concentration level of the particle fractions (PM10 and PM2.5) during the occupancy period does not satisfy the World Health Organization (WHO).
