Photochemical ozone creation potential

Derwent, R. G., Jenkin, M. E., and Saunders, S. M. Photochemical ozone creation potentials for a large number of reactive hydrocarbons under European conditions, Atmos. Environ., 30, 181-199, 1996. 

Analogous approaches to assessing VOC reactivities have been developed by Derwent and co-workers (e.g., see Hough and Derwent, 1987 Derwent and Jenkin, 1991 and Derwent et al., 1996) where a trajectory model is used to calculate the additional ozone production due to the addition of a particular VOC under conditions typical of air masses advected across northwest Europe toward the British Isles. The photochemical ozone creation potential (POCP) index thus calculated is a measure of the reactivity of the particular VOC in terms of 03 formation. Andersson-Skold and co-workers (1992) followed a similar approach for the summer conditions in southern Sweden.

DMC is classified as a non-toxic and environmentally compatible chemical [69]. In addition, the photochemical ozone creation potential of DMC is the lowest among common VOCs (2.5 ethylene = 100). The areas in which DMC acts, or can act, as a potential phosgene substitute correspond to the main areas of phosgene industrial exploitation, that is, production of aromatic polycarbonates and isocyanates, leading the production of these important chemicals out of the chlorine cycle.

Photochemical ozone creation potential (POCP) measurements can give some guidance to the choice of solvent which cannot be recovered because quantities are too small. Quite surprising differences of POCP may be found with very similar volatility and solvent properties. 

Ozone depleter Ozone depletion potential is the value relative to that of CFC-11. It represents the amount of ozone destroyed by the emission of gas over its entire atmospheric life-time. Photochemical ozone creation potential is a relative value to that of etiiene to form ozone in an urban environment. Numerous solvents belong to both groups.
