Air Quality Working Group (AQWG)

With the involvement of undergraduate and doctoral students, as well as researchers from other institutions, air quality has become one of the core research areas of the Environmental Technology Group. This research encompasses both outdoor and indoor environmental air. Under the leadership of Associate Professor Dr. Gábor Géczi, head of the group, the Air Quality Working Group (AQWG) has been publishing research outcomes (scientific articles and studies) since 2013 in areas such as:

• Nationwide assessment of air pollution in thermal baths, with a particular focus on hydrogen sulfide (H₂S) emissions.
• Investigation of chlorine exposure in indoor spaces associated with public swimming pools (including training and recreational pools), aimed at addressing both air quality and energy efficiency challenges (e.g., air temperature, fresh air supply), as well as parallel water quality issues related to disinfection.
• Indoor air quality studies, including analyses of air in residential buildings with special attention to radon (²²²Rn) and carbon dioxide (CO₂) concentrations, incorporating other comfort-related parameters (temperature, humidity, air movement) and building energy efficiency considerations.

AQWG is also responsible for recruitment into the postgraduate program in Air Quality Control and contributes to curriculum development and course delivery in the undergraduate Environmental Engineering program, specifically the Air Quality Control course.

Since 2021, continuous measurements have been conducted in three municipalities in Pest County and on the university campus using newly acquired laser-based PM sensors. These efforts to monitor and model particulate matter (PM) concentrations provide doctoral students with valuable research opportunities.

Two international researchers have joined the group: Dr. Kenza Khomsi (Casablanca, Morocco), who contributes as a co-supervisor, and Dr. Amine Ajdour (Agadir, Morocco), who, despite the lack of financial support, has joined as a postdoctoral researcher, strengthening the group’s publication output.

Achievements include the successful defense of a doctoral dissertation by Achraf Qor El Aine (Morocco) under the Doctoral School of Engineering Sciences in 2024. Houria Bouzghiba (Morocco) is currently pursuing her PhD in the Doctoral School of Environmental Sciences and is expected to submit her dissertation in 2026.

The group actively supervises thesis and diploma projects for students in Environmental Engineering and Environmental Management in Agriculture.
