Science: Ozone Depletion. In the stratosphere, the region of the atmosphere between about 6 and 30 miles (10 and 50 kilometers) above the Earth's surface, ozone (O3) plays a vital role by absorbing harmful ultraviolet radiation from the sun.Stratospheric ozone is threatened by some of the human-made gases that have been released into the atmosphere, including those known as chlorofluorocarbons ...

Halocarbons: Ozone Depletion and Global Warming Overview

Ozone Depletion and Global Warming Overview PAGE 1 OF 5 Halocarbons are chemical compounds containing carbon, one or more halogens, and sometimes hydrogen.

Ozone Levels - Environmental Factors Influencing Health ...

Ozone in the upper levels is beneficial because it protects the earth from the harmful ultraviolet rays of the sun. Ozone at ground level, however, is considered an air pollutant and can cause harm when inhaled. Ozone irritates our lungs, and can trigger many health problems including chest pain, coughing, throat irritation, and congestion.

Ozone Depletion Potential - an overview | ScienceDirect Topics

The Montreal Protocol (1987) identified refrigerants that were destroying the ozone layer and those with the potential of destroying it. The Ozone Depletion Potential (ODP) was defined in order to classify refrigerants. As they were the worst ones, R11 and R12 are assigned a value of unity, i.e., ODP-R11≡1 and ODP-R12≡1.

(PDF) Ozone Layer Depletion and Its Effects: A Review

The depletion on the ozone layer results in the arrival of the ultraviolet radiation to the surface of the Earth introducing the risk of eye cancer, skin cancers and infectious diseases because of ...

Direct Observation on p- to n-Type Transformation of ...

We demonstrated a complete transformation of perovskite surface region energetics from p- to n-type during defect passivation via a nature molecule, capsaicin. We further observed the p-n homojunction locating at ∼100 nm below the perovskite surface. The synergies between defect passivation and energetics modification not only promoted charge transport but also suppressed the defect-assisted ...

Ozone Layer Protection | Environmental Protection Department

May 17, 2019·Scientists have reached consensus that ozone depletion in the stratosphere is caused by ozone depleting chemicals. These chemicals contain chlorine or bromine atom with inherent chemical stability and have long lifetime in the atmosphere, in the range of 40 to 150 years. These chemicals and other trace gases drift up into the stratosphere and ...

Author information: (1)Department of Photobiology, St John's Institute of Dermatology, University of London, United Medical School of Guy's Hospital, UK. Thinning of the ozone layer is predicted to result in increased levels of ultraviolet (UV) B radiation at the earth's surface.

The Ozone Hole and Global Warming | Union of Concerned ...

Jul 16, 2008·Human activities cause ozone depletion and global warming. Ozone (O 3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.. Global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to …

Ozone Depleting Substances (ODS) and Synthetic Greenhouse ...

Why do we need to manage ozone depleting substances and synthetic greenhouse gases? The ozone layer protects life on Earth by absorbing ultra-violet (UV) radiation from the sun. UV radiation causes many problems from skin cancer and cataracts in people to damaged farm crops. The ozone layer is like sunscreen for the Earth – it reduces sunburn.

Ozone depleting substances | Ministry for the Environment

New Zealand is a signatory to the Montreal Protocol on Substances that Deplete the Ozone Layer which sets targets for reducing the production and consumption of ozone depleting substances.
