Collaboration proposal between Collaboration proposal between NCSR “DEMOKRITOS” & Almaty KAZAKHSTAN Dr. Thomas Maggos, Senior Researcher

Environmental Research Laboratory provides research activities and service provision in the field of air pollution and environmental protection, through R&D projects and contracts with National Authorities, industries, public and private companies respectively. The activities of the lab are focused on four main actions: Indoor and Outdoor Air Quality Impact of air pollution in Human Health De-pollution Technologies (Photocatalysis) Advice and Policy support on Environmental issues QA/QC EREL is accredited by the Hellenic Accreditation System S.A (ESYD) under the terms of ELOT EN ISO/IEC 17025:2005 Standard, to carry out the following tests: Sampling and determination of PM10 Determination of PAHs-collection on sorbent backed filters with GC-MS analysis Pumped sampling and analysis of benzene by GC / TDS

Indoor and outdoor Air Quality The current action focuses on the assessment and improvement of indoor and outdoor air quality through: Airborne Particulate Matter (TSP, PM10, PM2.5 and PM1) Volatile Organic Compounds (n-alkanes, aromatic H/C, aldehydes and ketones, sulfur compounds etc) sampling and analysis. Chemical characterization of PM for the detection of OC/EC, ions and PAHs and cross-correlation with atmospheric pollution indicators in order to estimate their origin. Receptor modelling application (Principal Component Analysis, Positive Matrix Factorization, Chemical Mass Balance, ME etc) for the identification of sources and quantitative assessment of their contribution. Continuous inorganic compounds measurements (NOX, SO2, O3, CO, CO2) Isokinetic stack sampling for the determination of air pollutants emissions from industries Meteorological measurements (WS, WD, T, RH) in order to investigate the role of meteorology to the recorded air pollutants’ values. Based on the above field measurements and using mathematical models we perform calculation of atmospheric pollutants dispersion in industrial and urban areas Assess the impact of Air Pollution on Human Health Estimation of the local population exposure profile This action aims at deriving exposure profiles representative of population subgroups, which will be used to quantitatively estimate the associated adverse health impact of the major air pollutants. To this aim an Agent Based Model (ABM) platform is used. The concentration-response functions established by WHO in the HRAPIE project will be used for the health impact assessment of the major air pollutants.

Materials’ ability to degrade air pollutants are examined through their Materials’ ability to degrade air pollutants are examined through their competence to photocatalytically decomposes them under controlled external conditions. Within a Specially Designed Reactor, the evaluation of the materials’ photocatalytic performance is carried out through the calculation of certain photocatalytic and chemical kinetics parameters. Additionally, the mechanisms of the chemical reactions taking place between nanomaterials and gaseous pollutants are investigated. For the needs of the photocatalytic experiments, EREL has constructed a 0.125m3 stainless-steel, cubic photocatalytic reactor according to the provisions of the ISO standard. The reactor: is light-sealed to avoid possible light interference is equipped with two cubic glassy environmental chambers of 0.001 m3 and 0.125 m3 volume capacity is equipped with up to 10 (UV or Vis) lamps for the provision of irradiation is equipped with two fans to prevent temperature fluctuations can operate under both dynamic and static conditions
