Ozone Depleting Potential. A measure of the capability of a particular chemical to destroy ozone, measured against CFC-11 which has an ozone- depleting potential of 1. For ODP values of ozone-depleting substances, see Substances and Sectors
See Ozone Depletion Potential.
Ozone Depletion Potentials (ODPs) provide a relative measure of the expected impact on stratospheric ozone per unit mass emission of a gas, as compared to that expected from the same mass emission of CFC-11 integrated over time. The Montreal Protocol uses steady state ODPs which represent the cumulative effect on ozone over an infinite time. By contrast, a 20-Year ODP is a time-weighted depletion rating, which provides a more realistic measure of medium-term depletion.
Ozone Depletion Potential. a number that refers to the amount of ozone depletion caused by a substance. The ODP is the ratio of the impact on ozone of a chemical compared to the impact of a similar mass of CFC-11. The ODP of CFC-11 itself is defined to be 1.0. Other ozone-depleting substances have ODPs ranging from 0.02 to 10. Several classes of substitutes have zero ODP because they do not contain chlorine.
Ozone depletion potential. A relative index indicating the extent to which a chemical product may cause ozone depletion. The reference level of 1 is the potential of CFC-11 and CFC-12 to cause ozone depletion. If a product has an ozone depletion potential of 0.5, a given weight of the product in the atmosphere would, in time, deplete half the ozone that the same weight of CFC-11 would deplete. The ozone depletion potentials are calculated with mathematical models that take into account factors such as the stability of the product, the rate of diffusion, the quantity of depleting atoms per molecule, and the effect of ultraviolet light and other radiation on the molecules.
ozone depletion potential. a measure of the capacity of a particular chemical to destroy ozone. It is measured against a standard: CFC-11 (chlorofluorocarbon), which has an ozone depletion potential of 1.0.
ozone depleting potential - new refrigerants have zero odp and therefore, if released do not deplete the ozone layer. However, they still must not be released to atmosphere.
