I would be grateful if you would take into account
in the
planning of your future work the following item
from the above.
13. The publication of the concentrations of gas
phase
constituents in smoke from German cigarettes was
discussed. It was felt that this was likely to be
expanded to cover a wider range of components,
which
might be expected to evoke a public reaction and
that
it would be followed up in other countries.
It was agreed that while we should not encourage
this
development we should aim in the event of
publication
that figures should be given for the weight of
constit-
ent delivered.
It was realised that these developments will give
rise
to marketing opportunities in some countries.
There
are a variety of possibilities arising from
research
which can come to fruition in this situation.
These
include carbon filters (including diffusion
filters),
mixed bed filters, synthetic resins and
ventilation.
The following constituents are listed in Hunter
Phase I
which could contribute to the gas phase:
Hydrogen cyanide
Steam-volatile phenols
Total volatile aldehydes,
Carbon monoxide
Total oxides of nitrogen
Organic nitriles
Oxides of sulphur
Hydrogen sulphide
Ammonia and primary amines
Nitrosamines,
Nicotine
