ets exposure, lung cancer - Legacy Tobacco Documents Library

ETS, such as banning of smoking, have little to no effect on
levels of these other pollutants or their health effects .
Some of these other pollutants have particular relevance t
Asia and especially Korea . A high use of automobiles, energy
conservation measures resulting in "tight", poorly ventilated
buildings, and the utilization of relatively polluting fuels ha e
contributed to making the indoor air in many Asian cities, ~
including a number of Korean cities, highly polluted . Thus, fo
example, studies in 1990 demonstrated that the mean sulphur
dioxide level in Seoul and several other Korean industrial
centers exceeded the applicable environmental standard, i .e ., t e
recommended safe exposure level .

recently, studies done in Seoul by Kim and associates have
demonstrated higher indoor than outdoor levels of not only carbbn
monoxide, but nitrogen dioxide and formaldehyde as well, largely
attributable to indoor cocking and heating, coupled with poo Ir
ventilation . These studies have also demonstrated that selected
homes in Seoul have significantly elevated levels of radon, a~
naturally occurring radioactive gas that is a potentially
important cause of lung cancer . I
Conclusions
our analysis of the data reveals that there is little to n~o
good evidence that chronic exposure to ETS is a health risk to I
adult individuals . While parental smoking appears to be f
associated with an increased incidence of acute respira-,-)r !'y
illness in pre-school children, no such finding or imoai-r-,ent c ;f
pulmonary function is consistently evident in school-age or oldI ~ar
children . The role of confounding variables and other factors,~
such as in utero effects of smoking during pregnancy, family
health history, and breast feeding, alone or in combination, on
the apparent association between parental smoking and r=_spiratc~ry
illness in young children remains to be elucidated . Althougtl
acute ETS exposure may produce eye, nose and throat irrication~in
a concentration-related fashion, there is little to no
that it results in adverse lower respiratory or cardiovascular (
