Funding: Hellenic Foundation for Research and Innovation (HFRI) and the General Secretariat for Research and Technology (GSRT) grant for support of Post-doctoral researchers as Principal Investigators.

Description: The project aims to evaluate the contribution of different sources to the atmospheric oxidative potential (OP) and their seasonal variability throughout a year in a heavily inhabited and polluted environment such as Athens and will provide an unprecedented dataset of ROS activity measurements both locally and regionally. A variety of state-of-the-art instrumentation and well established measurement techniques will be applied in continuous measurements and intensive field campaigns. The findings of PARADOX-H will unravel the OP-PM exposure link for the 5 million inhabitants residing in the Greater Athens Area throughout a year. It will provide important insight on the toxicity of various PM sources that can be linked to diverse health effects. Finally, PARADOX-H will quantitatively elucidate both the local and the regional influence of distinct aerosol sources in the area, inferring, thus, which sources systemically cause health problems to such a majority of the Greek population residing in Athens.

Role of APCG: Coordination of the project, implementation of measurements and dissemination of the results.
