Ozone depletion in the Stratosphere - A Report by B. Lever - Abstract

OZONE - Depletion in the Stratosphere


Theories for ozone depletion in the stratosphere are based on the ionisation of CFC’s and halogenated hydrocarbons to liberate chlorine through the sun’s radiation. After several years of measures to restrict their use the ozone continues to be depleted in the stratosphere.

Environmental researchers today are mostly concerned with global warming and increasing levels of carbon dioxide emissions and less with the regeneration of stratospheric ozone.

The ozone layer especially seen in the Arctic & Antarctic is still thinning with ultraviolet radiation becoming noticeably more intense (e.g. in Chile) but it is currently predicted that ozone will be regenerated within a few decades. There is no real evidence to support this optimism.

This report gives evidence for the formation of water vapour and polar mesospheric clouds in the upper atmosphere. It also predicts a continuous depletion of oxygen in the stratosphere. Oxygen from the lower atmosphere is necessary for the ozone regeneration process.

Leaked hydrogen from industry which depletes the ozone was estimated to be in excess of 100,000,000 cubic metres a year from power generation and water treatment plants throughout the world in 1985.

This amount together with leakage from the petroleum and gas producing industries could easily exceed 250,000,000 cubic metres a year today. However, hydrogen present in the general atmosphere is considered to be negligible and ‘climate neutral’.

Chlorine in the upper atmosphere associated with the hydrogen will be present as hydrogen chloride, hypochlorous acid (HOCL) and oxychlorides sourced from the electrolysis of sea water and volcanoes.

NASA the space agency that monitors the atmosphere has no real evidence for the cause of mini holes that space shuttles and rockets make in the ozone layer. The mini holes may be caused by unreacted hydrogen from the rocket’s fuel.
