— In the study, the team study, investigated the photochemical production of 1 O 2 by size-fractionated road dust collected in Edmonton, Alberta and compared the reactivity of this substrate to that of Arizona test dust, Niger sand, and Cape Verde dust. Researchers at the University of Alberta (Canada) have shown for the first time that road dust is photochemically active; i.e., sunlight causes chemical reactions in the dust.
