A scientific seminar was held at the Faculty of Ecology and Soil Science of Baku State University (BSU), where PhD student Orkhan Hajiyev of the Department of Ecological Chemistry presented findings from his dissertation research titled “Results of Active Biomonitoring of Atmospheric Air in Baku and Absheron Peninsula Using Sphagnum girgensohnii Moss Transplants.” The research is supervised by Doctor of Chemical Sciences, Professor Sevinc Hajiyeva and PhD in Chemistry, Associate Professor Zarifa Valiyeva.

During the seminar, Orkhan Hajiyev presented the outcomes of his environmental monitoring study. The project evaluated the quality of atmospheric air affected by industrial and transport activities using active biomonitoring methods, particularly through the use of Sphagnum girgensohnii moss transplants.

As part of the study, moss bags were installed at 21 locations. After a 12-week exposure period, collected samples were analyzed through instrumental neutron activation analysis (INAA), atomic absorption spectrometry (AAS), and gas chromatography.

The findings revealed concentrations of Na, Cl, I, Al, V, Pb, Th, U and other elements exceeding the Permissible Concentration Limits (PCL) at certain locations. Additionally, localized increases in toxic metals such as Cd, Cu, Ni, and Zn were detected. Polycyclic aromatic hydrocarbons (PAHs) were also found in several industrial zones.

The main sources of pollution were identified as petroleum refining and gas extraction facilities, metallurgy and chemical industries, and emissions from transportation.

The research offers a reliable overview of the current state of air pollution in the Absheron region. The applied methodology, proven to be effective under local conditions, is recommended for integration into future large-scale environmental monitoring programs.
