Oxides and acids of nitrogen play an important role in regulating
atmospheric radical levels, in particular, that of the OH radical the
main initiator of the degradation of chemicals in the atmosphere. A
comprehensive overview on the methods used to measure nitrogen oxides
and acids in the troposphere is given and difficulties and artefacts
associated with the use of the techniques for measurements in urban
and mega city environments is illustrated. State-of-the-art methods
for the measurement of OH and HO2 radicals are reviewed and recently
recognised difficulties, in particular with the measurement of HO2
radicals, are highlighted. Other contributions to the book cover our
present understanding of the gas, aqueous and particulate/aerosol
phase atmospheric degradation chemistry of volatile organic compounds
(VOCs) under NOx conditions typical of rural, urban and mega city
environments. Examples of measurements of NOx and VOCs in the
atmospheres of these environments are given, in particular for the
megacities Cairo and Beijing, in conjunction with modelling studies
which attempt to simulate the field observations using state-of-the
art knowledge on the chemistry of the VOCs and radical levels.
