Vancouver was first to sound the alarm just before 4 p.m. Saturday A few minutes later,
Environment Canada issued a similar alert.
They are as follows;
Air Quality Advisory
Metro Vancouver has issued an Air Quality Advisory for eastern parts
of Metro Vancouver and the Fraser Valley because of high
concentrations of ground-level ozone that are expected to persist
through the weekend.
strenuous outdoor activities during mid-afternoon, when ozone levels
are highest. Exposure is particularly a concern for infants, the
elderly and those who have underlying medical conditions such as
lung or heart disease and asthma. If you are experiencing symptoms
such as chest discomfort, shortness of breath, cough or wheeze,
follow the advice of your health care provider and stay indoors in
air conditioned spaces.
This advisory is expected to continue until there is a change in the
current hot and sunny weather.
Metro Vancouver works in cooperation with Environment Canada, the
Fraser Valley Regional District and B.C. Ministry of Environment to
look after air quality.

and the Fraser Valley communities and potential health impacts can

What is ground-level ozone?
Ground-level ozone is not emitted directly into the air. It is
formed when nitrogen oxides (pollutants emitted when fuels are
burned) and volatile organic compounds (emitted from solvents) react
in the air in the presence of sunlight.
The highest levels of ground-level ozone are generally observed
between mid-afternoon and early evening on summer days.
Tips to reduce your personal health risk:
Stay cool and drink plenty of
Use symptom management medications such as inhalers if needed.
Continue to manage medical conditions such as asthma, chronic
respiratory disease and heart failure. If symptoms continue to
be bothersome, seek medical attention.
Maintaining good overall health is a good way to prevent
health effects resulting from short-term exposure to air
And especially for persons with chronic underlying medical
conditions: Stay in cool, air-conditioned environments,
especially during the afternoon when ground-level ozone levels
are at their highest, and reduce indoor pollution sources such
as smoking and vacuuming.
Voluntary Emission Reduction Actions
Reducing air emissions throughout Metro Vancouver and the Fraser
Valley will be beneficial to air quality. Actions people can take:
Minimize the use of vehicles.
Consider taking transit or carpooling rather than driving to
Minimize the use of other gasoline and diesel engines, such as
lawn mowers and trimmers.
Avoid refuelling with gasoline during the hottest time of day.
Avoid idling your vehicle.
Nitrogen oxides (NOx) are emitted
from transportation sources, boilers, building heating systems
and other combustion processes.
Volatile organic compounds (VOC) commonly arise from burning
fossil fuels, solvent evaporation (including paint, varnishes
and thinners), fuel refining and storage, fuel refilling, and
agricultural activities as well as natural sources such as
Under provincial legislation, Metro Vancouver is responsible for
monitoring air quality, controlling industrial, commercial and
some residential emissions, creating long-term plans, and
conducting emission inventories for the Metro Vancouver region.
To help reduce air emissions throughout the Lower Mainland,
Metro Vancouver works cooperatively with the Fraser Valley
Regional District, the B.C. Environment Ministry, Environment
Canada and other agencies to develop and implement emission
reduction programs for businesses and local residents. Further
information about air quality programs in the region can be
found on Metro Vancouvers website at
