Short summary
Limonene is emitted in substantial quantities by plants, and also has indoor sources from air fresheners and cleaning products. We studied particle formation from the oxidation of limonene and found substantial quantities of oxidising components which are thought to be associated with the negative health effects of particulates. State-of-the-art measurements of the products of limonene–ozone chemistry were also presented.
