SUMAIVARY
Tiie resu
lts from Woo-Irose panels leave sliot..vn that
e
the impac of WNLIJ-:P.R1X DUAL FILTER cigarettes increas s
rLi,idly with increasing puff number, 'while the im:@;act
0- %-PAVZN SPZCIP.L MILD FILTER cigarettes or NALLMZ&R:@
cigarettes with no Gorlind on the filter increases only
slightly wit1a puff number.
An attempt has been wado to e::plcin this effect
in terns of the delivery par individual puff of various'
sm.oke components, especially nicotine. The extractable
nicotine level varied little Afroin puff to puff. The
total nicotine delivery (and the absoluto &-mount of
extractable nicotine delivered) in@zeased u-ith x@uf`
number at a faster rate for than f o r C,"j-. V E N
SPECIAL MILD. However, for any particular puff nu-.ub--r
the delivery of total.and extractable nicotine uas less
for i!ArjL:,!A.V'% than for CRAVLN SPLCIAL MILD.
The delivery of TPA, total volatile '-..,ases and
am-lonia, the smoke pH, the TPZN/aicotine ratio and the
efficiency of the filters for nicotine and TPU ware
measured, but these factors failed to show a reason for
the observed impact effect.
The affect appears to be da-acndGat or. the prcsance
in the filter of Gorlind which intcracts with one of the
smo'%-e components, but the s,-o2:e ccmponent rcszon::-;blc for CD
the eAffact haz; not bcor.
