FLUOROCARBON-OZONE. POTENTIAL OZONE DEPLETION DUE TO CFCS.

Type of article: Periodical article

Summary

ALL PREDICTIONS HAVE BEEN MADE ON COMPUTER PROGRAMS WHICH ANALYSE THE CHEMICAL REACTIONS TAKING PLACE. EARLIER PROGRAMS CONSIDERED THE EFFECT OF ONE COMPONENT AT A TIME AND PREDICTED AN EVENTUAL DEPLETION IN THE OZONE LAYER OF 16.5% DUE TO THE RELEASE ON EARTH OF FLUOROCARBONS. AS KNOWLEDGE OF THE REACTIONS BECAME BETTER UNDERSTOOD THIS FIGURE HAS BEEN REDUCED TO BETWEEN 5 AND 9%. HOWEVER A PREDICTION HAS NOW BEEN MADE USING A PROGRAM WHICH STUDIES THE SIMULTANEOUS EFFECT OF A NUMBER OF MATERIALS INCLUDING NITROGENOUS FERTILISERS, CARBON DIOXIDE AND AIRCRAFT EXHAUST AS WELL AS FLUOROCARBONS. THIS STUDY SHOWS NO DEPLETION IN THE OZONE LAYER BETWEEN THE YEARS 1911 TO 2100 AND CURRENT MEASUREMENTS SEEM TO AGREE THAT IF A CHANGE IS OCCURRING IT IS SLOW. D.W.H.
