Ecposure to particulate matter PM₂.₅ and PM₁₀ in Hospital Wards, Kuala Lumpur / Nur Shahadah Yahya
The particles in the air that contribute to air pollution are made up of hundreds of different chemicals. Some of the particles were emitted through directly from the sources known as a primary pollutant such as particulate matters, which are suspended particle. Since many people were not realized a...

The particles in the air that contribute to air pollution are made up of hundreds of different chemicals. Some of the particles were emitted through directly from the sources known as a primary pollutant such as particulate matters, which are suspended particle. Since many people were not realized about the indoor air pollutants are more dangerous compared to outdoor air pollutants and it can cause bad health effects to human’s health especially respiratory problem. The public area such as the hospital is one of the places which the respiratory problems often happened. The main sources of particulate matters at the study location were mobile emission because the building of hospital wards was surrounded by the busy roadsides and also exposed to the construction activities. The aims of this study was (i) to determine the concentration of particulate matter PM₂.₅ and PM₁₀ in hospital wards, Kuala Lumpur, (ii) to compare the concentration of particulate matter PM₂.₅ and PM₁₀ at every Floor Level of hospital wards and (iii) to measure the exposure assessment of particulate matter PM₂.₅ and PM₁₀ concentration to workers in hospital wards.
