Title: Chemicals in the atmosphere: Solubilities in aqueous
Media
Task Group
Chairman: P.G.T. Fogg
Member: J. Sangster
Remarks: Series: Wiley Series in Solution Chemistry
Completion Date: 2002 - project completed
Objective:
To produce a book containing an account of interaction of chemicals
in the atmosphere with aqueous systems. Relevant solubility data form
a major portion of the book.
Description:
Solubilities of natural and man-made gases and vapours present in
the atmosphere are important in determining their fate in the environment.
A high solubility implies that the gas or vapour will be readily removed
from the atmosphere by rain. A low solubility implies that it will be
removed more slowly.
The book covers the description and experimental measurement of phenomena
related to dissolution in an aqueous phase of stable and unstable species
in the atmosphere. It includes:
(i) The collection, evaluation and publication of solubility data
which are fundamental to the understanding of:
- (a) the partitioning of gases and vapours between aqueous solutions
and the atmosphere;
- (b) chemical processes occurring in clouds and other aqueous environmental
aerosols.
(ii) The evaluation of theoretical models to interpret or predict solubilities
in solutions containing dissolved componenets, and with compositions
typical of atmospheric clouds and other natural waters. Substances are
included if
- (a) aqueous solubility is important in determining the release of
the substance to the atmosphere, from the oceans for example, or its
removal from the atmosphere;
- (b) a substance, though its physical solubility may be low, is involved
in important aqueous phase reactions.
Progress:
The project involves the cooperation of 10 contributors who are
either chemists or atmospheric physicists. There has been appreciable
progress during the past year. A contract for publication by John Wiley
& Sons (England) has been agreed, as a volume in "Wiley Series
in Solution Chemistry".
