Eleven working groups are currently active inside European Aerosol Assembly (EAA), covering a wide range of research interests: atmospheric aerosol processes, aerosol-based nanotechnology, combustion aerosol, electrical effects, instrumentation, PMx, indoor and working place aerosol, fundamentals, aerosol chemistry, aerosol modelling, and inhalation, exposures and health. EAA holds an annual European Aerosol Conference (EAC) with the participation of research groups from all over the world. Next EAC meeting will be EAC 2017, in Zurich. During the EAC 2017 the following special sessions will be organised: - Education, Careers, and Outreach in Aerosol Science. - Aerosols in Earth System Models - Electronic Cigarettes - Scientific Evidence - Targeted Generation and Delivery of Aerosolized Medicines -Electrohydrodynamic Atomization (EHDA) Technologies: from Fundamentals to Application.
