Ozone precursors



At ground level, ozone (O3) is formed by a series of reactions, including sunlight, involving VOCs combining with NOx. VOC and NOx are called ozone precursors.

Does anyone know what solvent cleaners/degreasers are considered ozone precursors and photochemically reactive for forming ground level ozone?

Thanks,
