The Environmental Technology Centre (ETC) of
Environment Canada
deals primarily with the measurement of air pollutants in
ambient air,
air pollutants emitted from
mobile and
stationary sources,
the analysis of a wide variety of organic and inorganic compounds,
and the provision of technical research and development to support
these and other activities. Following are some of the ways ETC is
involved in keeping our air clean...

Naps Network keeps an eye on the sky...
The National Air Pollution Surveillance
(NAPS) Network;
working with the provinces and regional authorities over 30
years to measure air quality across Canada.

Air Quality Trends in Canadian Cities
In 1969, the federal government introduced the
Clean Air Act to address the problem of air
pollution. And in fact, 1994 marked the 25th
anniversary of a federal-provincial program that
measures air pollution in Canada, the National
Air Pollution Surveillance (NAPS) Network. The
network provides important information on
common pollutants
to which Canadians may be exposed in the air they breathe.

Regional Smog Episode Animations
Animations of
regional scale episodes of ground
level ozone where concentrations exceeded the Canadian acceptable air quality
objective level of 82 ppb over very large regions of Canada and the
United States.

Emissions Research and Measurement division
ERMD has had a lead role in measuring and analyzing air quality and exhaust
emissions for over two decades. The team of engineers, chemists and technologists, based at the
department's centre of technical expertise for air quality issues, conducts laboratory
and field studies of air pollution originating from
mobile and
stationary sources.
A key focus of the group is to support the research and development of new
technologies which help reduce pollution. ERMD is involved with emissions from
vehicles,
aircraft and
marine vessels.

Little vehicles, big problems...
In Pakistan, vehicle emissions account for
90% of air pollution. EC and others are working on a way to reduce the fumes
from a major troublemaker, the auto-rickshaw.
