40.

........ . In poorly ventilated buildings,
chemical vapours emitted by furnishings
and building products can build up, as can
fumes from smoking, cooking and heating.
Airtight, energy-efficient houses and other
buildings can make the problem worse.
Moreover, the health risks are increased by
the fact that most people spend 80 to 90
percent of their time indoors.

More and more people are becoming
concerned about the effects of passive
smoking on children

Experts fear that air pollution worldwide is
on the increase as more nations become
industrialised

The air we breathe indoors may pose an
even greater health threat than outdoor
pollution

Emissions from the average car have been
reduced by the introduction of new
technology

Environmental pollution is probably the
most serious threat posed to the survival of
our planet
