Presentation abstract: We know that nothing is more fundamental than the air we breathe. Deprived of it, we would die within minutes yet keeping it safe for humans remains an aspirational challenge. From ultrafine particles that form in the air through complex physicochemical processes involving gaseous precursors to large respiratory particles containing pathogens, the composition of the air impacts our health, as quantified in numerous studies on disease burden and airborne transmission of infections. In recent decades, the scientific understanding of every aspect of particles in indoor and outdoor air has expanded enormously thanks to the interdisciplinary efforts of experts from all scientific, engineering, public health, and related practice disciplines. However, in practice, a lot of this knowledge is not used to control particle sources or reduce exposure to them. Pieces are missing from the puzzle of science, technology, applications, and regulations that protect us from the risks of inhaled particles. How can we complete this puzzle?
