The contribution of individual compounds to ozone depletion is characterized by the ozone depletion potential ODP. The reference level of 1 is assigned as an index to CFC-11 and CFC-12. One chlorine can destroy 100000 molecules of ozone.

Ozone depleting potential ODP is a relative index of the ability of a substance to cause ozone depletion. For each ODS this page provides the compounds atmospheric lifetime Ozone Depletion Potential ozone depletion potentialA number that refers to the amount of ozone depletion caused by a substance. Ozone depletion potential ODP The ozone depletion potential ODP of a chemical compound is the relative amount of degradation to the ozone layer it can cause with trichlorofluoromethane CFC-11 being fixed at an ODP of 10.

If the ozone layer gets depleted more UV rays enter the atmosphere. From which of the following does the ozone. The ability of a substance to destroy ozone in the stratosphere c.

CFC 11 or R-11 has the maximum potential amongst chlorocarbons because of the presence of three. In our body Vitamin D is synthesized when it reacts with UV rays. Ozone Depletion Potential ODP has traditionally been defined as the ratio of model calculated ozone depletions under steady state conditions.

Larger values indicate more potential to deplete ozone. The ability of a substance to cause global warming b. The study was the first to calculate the ozone-depleting potential ODP of N 2 O.

Its ability to destroy stratospheric ozone. Thus the ODP of CFC-11 is defined to be. To get a card you need to.

Table of halogen source gas names chemical formulas surface emissions lifetimes ODP and other names by which they are. It is destroyed more quickly than it is created. A rating of health hazards caused by ozone depletion.

Conecioue of the potential climatic effecta of emi11ion1 of the1e 1ubatance1 Aware that meaeures taken to protect the ozone layer from depletion ahould be baaed on relevant ecientific knowledge taking into account teclmical and economic conaiderationa Deterained to protect the ozone layer by taking precautionary aea1ure1 to. More specifically it is defined as the ratio of calculated ozone column change for each mass unit of a gas emitted into the atmosphere relative to the calculated depletion. The ability of a substance to cause global warming b.

The rating of health hazards caused by ozone depletion d. The ability of a substance to destroy ozone in the stratosphere c. Ozone Depletion Potentials ODPs provide a rel ative measure of the expected impact on ozone per unit mass emission of a gas as compared to that expected from the same mass emission of CFC-11 integrated over time Wuebbles 1983.

Ozone Depletion Measurements of Different Products HCFCs are thought to be between 0001 and 011 ie. Chlorodifluoromethane R-22 for example has an ODP of 005. Currently 147 of the 196 Parties to the Montreal Protocol meet these criteria they are referred to as Article 5 countries.

Whose annual per capita consumption and production of ozone depleting substances ODS is less than 03 kg to comply with the control measures of the Protocol. The ozone depletion potential ODP of a chemical compound is the relative amount of degradation to the ozone layer it can cause with trichlorofluoromethane R-11 or CFC-11 being fixed at an ODP of 10. What does ozone depletion potential or ODP measure.

Ozone Depletion Potentials. Are calculated with respect to this reference point. Complete a one-day course.

The ODP is the ratio of the impact on ozone of a chemical compared to the impact of a similar mass of CFC-11. Well issue your certification card after youve completed training. The ability of a substance to destroy ozone in the stratosphere.

When these UV rays come in contact with the human skin it can cause malignant skin cancers. The length of time a refrigerant stays in the atmosphere. Up to 1000 times less degrading than CFC-11 which has a value of 10 whilst other substances such as Pentane have an ODP of zero ie.

This is the process of ozone depletion and has already caused a substantial amount of damage to the ozone layer. Receive a mark of 75 or higher. ODP can be estimated from the molecular structure of a given substance.

Using a well-established methodology the study calculated the ODP of N 2 O under current atmospheric conditions to. The ODP of CFC-11 is defined to be 10 and the ODPs of other compounds. Replacing CFCs used in air conditioners and refrigerators Hydrofluorocarbons HFCs have been identified as potential replacements for CFCs which is the major cause of Ozone Layer Depletion as they have an Ozone Depletion Potential of 0.

Use of HFCs in place of CFCs will go a long way in protecting our Ozone layer from getting depleted. Ozone Depletion Potential ODP is the ratio of the ability of a substance to degrade ozone to that of chlorofluorocarbon-11 CFC-11. ODP is calculated with respect to CFC-11 CFC-11 has an ODP of 1.

What does ozone depletion potential or ODP measure. One chlorine atom has the potential to destroy more than 100000 ozone molecules. It can also cause cataracts.

Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. The concept of ozone depletion potential ODP is widely used Wuebbles et al 1983. This happens when the chlorine and bromine atoms in the atmosphere come in contact with ozone and destroy the ozone molecules.

To purchase and handle refrigerants in Ontario you need an Ozone Depletion Prevention ODP certificate card. Ozone Layer Depletion Effect on Human Beings. The ozone depletion potential ODP is a measure of the potential of a compound to destroy ozone.

Solomon and Albritton 1992 as a measure of the effectiveness of a given compound in removing ozone relative to a standard compound which is taken to be. ODP is the ratio of ability of a substance to degrade ozone to that of chlorofluorocarbon-11 CFC-11 which therefore has a value of 1. The ability of a substance to cause global warming.

The ODP of a compound as normally defined is the ratio of the global loss of ozone ie integrated over latitude altitude and time from that compound at steady state per unit mass emitted relative to the loss of ozone. The rating of health hazards caused by ozone depletion d.
