That New Home Aroma May Disguise Bad Air

Smog alerts have become part of summer in big cities like Toronto,

Vancouver and Montreal but air pollution--the scourge of our urban society--is

more of a problem in Canadian houses, condominiums, and buildings than outside

of them.

According to Canada Mortgage and Housing Corporation (CMHC), indoor air

quality can be up to five times more polluted than outdoor air. " The level of

some contaminants can be up to 100 times greater inside buildings and 1,000

times more potent in a new or recently renovated workplace, " reports a senior

CMHC researcher.

Your home, your haven, your sanctuary, may be your worst enemy.

Twenty-five percent of Canadians have asthma, allergies or another

respiratory condition aggravated by poor indoor air. Since Canadians spend an

average of 90% of their time inside one building or another, indoor air quality

is a health concern.

How can this invisible threat occur in a tidy, clean home? Sometimes it is

built in, sometimes it grows and sometimes it occurs by accident. Depending on

your sensitivity, you may be troubled by anything from furniture to wallpaper

and from caulking to combustion gases. In new and remodeled homes, some building

materials and furnishings can give off toxic chemicals. In older homes, dampness

can encourage the growth of molds and fungi. Problems with furnaces, ventilation

and appliances can occur in any home. Outside pollutants, biological and

chemical, may " leak in " and mix with indoor contaminates to create or intensify

interior hazards.

To improve indoor air quality, focus on two questions: How do I keep

what's inside from polluting the air? and How can I get more clean air in while

conserving energy? The answer lies in three words: eliminate, separate and

ventilate.

One good source of healthy air strategies and air quality solutions is

British Columbia's Healthy Home Centre, a joint project of CMHC and Safe Start,

a provincial injury prevention program The Centre produces the unique Healthy

Housing BC Directory, which focuses on healthy indoor air products and services

available in BC, including contact information for many manufacturers.

The Directory warns that moisture levels, air temperature, physical aging

and rough or porous surfaces can cause air quality problems. This resource

listing offers suggestions on which materials have the greatest impact on what

you breathe and raises some important questions: How much of the material will

be exposed to indoor air? Will the material be installed in close proximity to

the home's occupants or air handling systems? If the product emits gases or

dusts, what is the hazard level? Is the material likely to break down during its

service life?

The Healthy Home Centre offers a Healthy Home Kit that leads you to

solutions such as:

a.. Use air-friendly paint, furniture and cleansers which have no or low

volatile organic compounds.

b.. Install carbon monoxide detectors to alert you to a deadly gas you

cannot smell.

c.. Install a balanced ventilation system with a heat recovery

ventilator that eliminates stale air and replaces it with fresh air.

Remember, that " new " smell may be hazardous to your health.
