A new method of producing oxidized mercury species in the gas phase

Researchers Jan Gačnik and dr. Igor Živković together with colleagues from the Department of Environmental Sciences and the Department of Gaseous Electronics of the "Jožef Stefan" Institute and a colleague from Argentina under the leadership of prof. dr. Milena Horvat developed a new method of producing oxidized mercury (Hg) species in the gas phase. 

Measurements of mercury in atmosphere in surroundings of active volcano Stromboli, Panarea, Italy

Volcanoes with accompanying phenomena are main natural source of Hg in the atmosphere that contribute several hundred tonnes of Hg on yearly basis. Within the collaboration with Istituto Nazionale Geofisica e Vulcanologia from Palermo (INGV), Italy, and CNRS, Mediterranean Institute of Oceanography from Marseille (MIO), France, in the last week of May, Asst. Prof. Dr. Jože Kotnik performed measurements of Hg in atmosphere on several locations around active volcano Stromboli over marine surface as well on nearby island Panarea.

Sampling of water and sediment in the Gulf of Trieste

Between 18. and 19. 2022 May co-workers of the Department of Environmental Sciences, dr. Jože Kotnik, Stojan Žigon and Ali Saeed, and visitors from University of Brussels, Vincent Perrot and Tianhui Ma, performed sampling of water and sediment around Soča River inflow in the Gulf of Trieste.

VIDIS SUMMER SCHOOL 2022 (July 5th-8th, Borkovac, Serbia)

The Summer School is organized as part of the H2020 VIDIS project, and it will showcase the most recent research and development activities related to air quality and atmospheric aerosols. VIDIS summer school aims to present innovative methods and tools in air quality and atmospheric aerosols monitoring, modelling and management. The summer school will provide participants with both theoretical knowledge and hands-on experience in relation to low-cost PM sensors, and other sensing technologies for air quality management and control.
