The course Indoor Air Quality belongs to the scientific area of air pollution.

The course focus on human exposure and dose in the indoor environment. Air pollutants arising from the indoor environment are studied, as well, as transport of pollutants from the outdoor environment indoors. Specific pollutants are studied as those arising from smoking, ozone, radon, carbon monoxide, heavy metals, asbestos, formaldehyde and PAHs. In addition, it is studied the dynamics of particulate matter and bioaerosols indoors including physico-chemical processes. Building characteristics are also examined and climatic parameters. Microenviromental models are also introduced together with applications in the different indoor environments. Measurement techniques in the indoor environment is also examined and human health effects. We focus on air quality in schools, public places and hospitals. During the lab work the students receive all the necessary skills to perform the laboratory exercises. Upon successful completion of this course the students will acquire new knowledge and specific skills on the following subjects:

• Will have knowledge of air pollutants and their physico-chemical characteristics in the indoor environment.
• Will learn the methods and techniques for measuring air pollutants.
• Will be able to understand microclimatic conditions indoors.
• Can compose a microenvironmental model and apply it in different indoor environments.
• Can evaluate or assess human exposure and dose from air pollutants.
• Can analyze air quality data.
• Can work with writing a simple scientific report on measurements of air pollutants.

• Adaptation ability
• Decision making
• Work in teams
• Advance of free, creative and inductive thought

Use of Information and Communication Technology

• E-class support with specialized educational material (Extra lectures for better understanding basic principles, additional exercises, proposed literature)

Assessment Method

Ι) 3 group (per 3 persons) laboratory reports (10%) delivered within the semester of the course.

Ι. Written final examination of the theory (65%) involving 3 or 4 exercises covering the whole curriculum.

III. A project on modelling the physicochemical processes of PM indoors (25%).

It is noted that each student must have a grade ≥ 5 in each of the above assessment procedures.
