Diverse definitions of the term VOC are in use. Some examples are presented below. Health Canada classifies VOCs as organic compounds that have boiling points roughly in the range of 50 to 250 °C (122 to 482 °F). The emphasis is placed on commonly encountered VOCs that would have an effect on air quality. WebReactive organic gases (ROG) undergo a series of reactions to form radicals. The alkylperoxy radical (RO2*) reacts with and oxidizes NO to form NO2 faster than NO reacts with O3 to produce the same result. Thus, when ROGs are present, it is likely that O3 will not be destroyed to produce NO2, and the null cycle is broken.
