Ift1h A"r4l. 1957
The main purpose of this visit van to discume the
position
of vork an the presence of 31,419010 Dibenspyrons
In tobacoo omakes
The amoke gra at Bristol has done memo preliminary
mossisrements on a suvle of 340820 D.D.P. and
their ultra-violet
absorption and fluorescence spectra agree vith
cnwn at Sautbampton.
This in all I.T.Co. have done an it, and I believe
they do not Intend
to do any more, though Bentley van of the opinion
that someone should
tackle the probles. At Bouthampton ve have carried
out ams, Initial
runs vith 3s,4s9s1O D.D.P. on m-luminsp In order
that we my have saw
knowledge of Its chemistry should it be required
that v9 tackle the
problem..
If we are to tackle this problem it vill take um
of the
order of six months to establish vhother or net
the compound In
MUM
present In smoke in sufficient quantity to cause
concern.
BORSTAL
X.T.Co. are now maia1 concerned with experiments
for DORSTAL
reduotionj theq do not appear to Ibe carrying out
ari7 experiments on
variation In BORSTAL ocacentration along a
cigarette am ve are dowe
I was Interested to hear that they on t duplicate
the RAnd findings
of BOUTAL reduction using ammonium sulphaftte, and
tend to regard
the vork of Alvard, Carden and Band with
conciderable doubt.
