TLDR
These results fail to demonstrate a learning deficit in a T-maze discrimina- tion despite a substantial decrease in cortical noradrenaline caused by bi- lateral locus coeruleus lesions.Abstract:
A report by Cicerone et al. (1974) concerned with the potential size of the atmospheric perturbation produced by man-made chlorofluoromethanes is considered, giving attention to a number of errors made in the first investigation and their correction. However, the corrections do not significantly change the results reported. It had been found that chlorine oxides which arise from chlorofluoromethane usage will within 10 or 15 years provide a sink for stratospheric ozone which will dominate the natural sinks for ozone.read more

Stratospheric Ozone: An Introduction to Its Study
TL;DR: In this paper, an analysis is made of the various reactions in which ozone and atomic oxygen are involved in the stratosphere, and the predicted effects of these reactions are determined based on the vertical distribution of the H2O, CH4, and H2 dissociation by reaction of these molecules with electronically excited oxygen atom O(¹D).

Fragmentation of aliphatic chlorocarbons under low‐energy (≲10 eV) electron impact
TL;DR: In this paper, the fragmentation of ten aliphatic chlorocarbons (CHCl3, 1,1,1 −C2H3Cl3 and C2Cl4) under low-energy (0 −10 eV) electron impact has been investigated with a time-of-flight mass spectrometer.

Stratospheric sink for chlorofluoromethanes: chlorine atomc-atalysed destruction of ozone
Mario J. Molina,F. S. Rowland +1 more
TL;DR: Chlorofluoromethanes are being added to the environment in steadily increasing amounts as discussed by the authors and these compounds are chemically inert and may remain in the atmosphere for 40 to 150 years, and concentrations can be expected to reach 10 to 30 times present levels.

Flux of Gases across the Air-Sea Interface
Peter S. Liss,P. G. Slater +1 more
TL;DR: In this paper, the use of a two-layer model to estimate the flux of various gases across the air-sea interface has been described, and the model has been used to estimate flux of different gases across different regions of the world.

Stratospheric ozone destruction by man-made chlorofluoromethanes.
TL;DR: Present usage levels of chlorofluoromethanes can lead to chlorine-catalyzed ozone destruction rates that will exceed natural sinks of ozone by 1985 or 1990.

Estimates of possible future ozone reductions from continued use of fluoro‐chloro‐methanes (CF2Cl2, CFCl3)
TL;DR: In this paper, it was concluded that very large reductions in ozone concentrations above about 30 km may result from the continued use of fluoro-chloro-methanes (CF2Cl2 and CFCl3), which are dissociated by ultraviolet radiation in the stratosphere and mesosphere, thereby giving rise to ozone-attacking Cl and ClO.

Infrared Measurements of Stratospheric Composition
TL;DR: In this paper, the observational techniques and results of i.r.t. measurements of the minor and trace molecular composition of the lower stratosphere are reviewed and the theoretical aspects of the analysis are discussed.
