The Dirty Facts

The Dirty Facts



9 out of 10 breaths we draw are likely drawn indoors: at school, the workplace,

restaurants, movie theaters and home.

The average person breathes in 50,000 pollution particles a day, and takes 20,000

breaths a day.

Poor indoor air quality can cause or contribute to the development of chronic respiratory

diseases such as asthma and hypersensitivity pneumonitis. It can also cause

headaches, dry eyes, nasal congestion, nausea and fatigue.


Children are most susceptible to indoor air pollution as their small bodies and

undeveloped immune systems are less able to effectively cope. Also children’s lungs

are still developing, they breathe faster than do adults and they tend to absorb

pollutants more readily. For children and adults, this all translates to immune

deficiency, lowered IQ rates, headaches, depression, anxiety, inability to concentrate,

attention deficit hyperactivity, shortness of breath, joint pain, sexual problems, memory

loss and cancer.

According to the Canadian Institute of Child Health (published The Health of Canada’s

Children 2000), Canadian children are exposed daily to a toxic soup of chemicals in

their water, air and food, and that exposure may explain the dramatic rise in childhood

cancers, asthma, sudden infant death syndrome and behavioral problems. The

chronic, low-level exposure to pesticides, smog, food additives and other chemicals

could also create a host of public-health problems for coming generations, including

limiting the ability of prospective parents to conceive. The report states there has been

a 25% increase rate of childhood cancers in the past 25 years, all believed to be

influenced by exposure to environmental contaminants. Asthma is now the leading

cause of hospital admissions in Canada, and the most frequent trigger for an attack is

air pollution.

Pollutants including lead, mercury, pesticides, PCBs and dioxins can reduce

intelligence and slow central nervous system development in fetuses.

A Canadian study conducted on hyperactivity disorder, among 20,000 children

nationwide, found 11% of children have been diagnosed with the disorder, compared

with less than 3%, 20 years ago. Some research has pegged the level among US

children at 17%.

Canadian children spend more than 90% of their time indoors, in the home (especially

with the lure of personal computers and video games), school, hockey arenas and

shopping malls. Research has shown that concentrations of pollutants can be up to

100 times higher indoors than outdoors.

Volatile Organic Compounds

The growth of synthetic chemicals after the 1960’s has been phenomenal. US

production alone increases tenfold in each decade. By the 1980’s, 4 million new

chemicals had been recorded, of which 60,000 were in common use, with around 1000

being added to this every year.

An average home now probably stores more chemicals than a chemistry lab at the turn

of the century, about 62,000 chemicals - most of them in the kitchen and bathroom.

The Hazardous Products Act requires that manufacturers list only certain volatile

organic compounds in their products. Chemicals can evaporate right through a

container that isn’t properly sealed.

Volatile Organic Compounds are off-gassed from new furniture, often lacquered with

formaldehyde, particleboard paneling or shelving, stuffed furniture (often coated with a

stain treatment) and even carpeting. VOC’s are also emitted from air fresheners, rug

deodorizers, household cleaning products, dry cleaned clothing, glues, paints, solvents,

pesticides, garden chemicals, personal care products and more.

There are approximately 9000 Volatile Organic Compounds found in recently sprayed

perfume - similar to numbers found in butane. Toluene, a chemical in almost all

fragrances, is believed to trigger asthma attacks and other side effects.

Aerosols and air fresheners contain dozens of volatile organic compounds such as

xylene, ketones and aldehydes. The University of Bristol found that pregnant women

who used aerosols and air fresheners most days, suffered 25% more headaches than

those who used them less than once a week. The frequent users also experienced a

19% increase in postnatal depression. A study in Edinburgh found that babies under 6

months old who were exposed to air fresheners on most days, had 30% more ear

infections than those exposed once a week, plus they had a 22% increase with


According to the American Lung Association, carpets emit volatile organic compounds,

as do products that accompany carpet installation such as adhesives and padding.

Symptoms include eye, nose and throat irritation, headaches, skin irritations, shortness

of breath or cough, and fatigue. Carpet can also act as a sink for chemical and

biological pollutants including pesticides, dust mites, and fungi.

Carpets, drapes, bedding and stuffed animals are all dust magnets. A 6 year old pillow

can get 1/10 of its weight from mites and mite droppings.


Damp, moldy homes are becoming more of a problem, according to the Canada

Mortgage & Housing Corp. Tighter homes make our indoor environments more prone

to contamination by molds, spores, fungus, and mildew. Tighter homes can keep

moisture trapped. Use of more outside air for ventilation can also make a building

mold-prone, if that outside air is moisture-laden. Sinks, toilets, tubs, soap dishes and

floors are prime targets for mold. While some molds are benign, others are toxic. Mold

can suppress the immune system. One can become immediately sensitized and

develop allergies upon contact with large areas of mold growth.

Different species of mold have different potential health effects. Pathogenic molds are

those that can cause disease in humans. Toxigenic molds are those that contain

potent poisons (mycotoxins), usually on the surface of the spores. The spores of the

pathogenic and toxigenic molds can be harmful even after the mold colony has stopped


When spores are airborne or the fungal mass is disturbed, an occupant with preexisting

allergies to molds will react with running nose, eye and throat irritation, cough,

etc. Prolonged exposure to mold in buildings may result in development of allergies in

individuals who did not have allergies to mold before. Asthmatics are at risk of reacting

to indoor mold with more frequent and severe attacks.

Symptoms associated with toxigenic molds include headache, sore throat, cough, skin

rash, flu-like symptoms, nosebleeds, fatigue, fever, etc.

High exposures to stachybotrys chartarum have been implicated in several cases of

infant deaths in homes.

Bird and bat droppings are often infected with pathogenic molds and are a special

concern in renovation and demolition of older buildings.

Moldy materials remain allergenic, infectious, or toxic even after the surfaces have dried

and further growth has stopped.

Tobacco Smoke

Tobacco smoke contains more than 4700 chemicals including cyanides and carbon

monoxide. The chemicals linger past the burn, absorbed into drapes, linens, furniture

and clothes.

According to Dr. Kenneth Chapman, director of the Asthma Centre of the Toronto

Hospital, new smoking trends are fueling the rise in asthma. Although many people

have kicked the habit in recent decades, we have actually been losing the war against

smoking in young women of child-bearing age. Studies suggest that children and

fetuses exposed to cigarette smoke are more likely to develop asthma.


Both scientific and anecdotal evidence is mounting that the flames of candles, whether

aromatic or unscented, release black soot into interior environments. They also can

load the air with deep respirable particles that some compare to the particulate hazards

of second-hand tobacco smoke.

Candle burning and smokeless oil lamps often leave a trail of ghost images and

mysterious soot tracks on carpets, walls, ceilings and furniture.

Candles can vary in their soot generation, as some can produce 100 times more soot

than other varieties. A candle placed in an air draft can increase its soot production by

a factor of 50.

Soot production from certain candles can be significant and may cause indoor levels of

airborne soot to exceed concentrations allowed in outside air by the Environmental

Protection Agency.

Candle sales in the US have increased 400% in the past seven years, to approximately

$2 billion. A significant portion of the growth is in the aromatic candle market, which

now amounts to an estimated $750 million annually.


The thrust for lead abatement in the US was primarily due to health concerns. It was

recognized decades ago as a serious problem that affects children. (Research and

documentation could fill a small library).

A US federal regulation requires real estate agents and owners of dwellings built before

1978, to disclose the property’s lead history and the health hazards related to lead.

A rough gauge of how low a priority lead is in Canada, is reflected in the fact that

Deleading magazine, the official publication of the US National Lead Abatement

Council, is circulated to 8000+ readers per month in the United States, but less than

twelve issues are sent to Canada.

The population most likely to be affected by lead poisoning in Canada are the young

and the poor, as they have the least amount of protection. The older buildings that

contain lead paint are usually inhabited by lower income families. Child occupants

(especially those under the age of ten) are at the greatest risk, and are the most

adversely affected by lead poisoning. In many municipalities, the demolition of

buildings is allowed with no site assessment for hazardous materials.

Household Pets

A study conducted in East & West Germany, by Dr. Erika von Mutius of the University

Children’s Hospital in Munich, found that childhood asthma rates were very few for

children living in a heavily polluted city of the former Communist block, than in a

relatively cleaner city of the West.

House pets, especially cats are major culprits to initiate asthma and allergy attacks.

Cats have grown in popularity among urban dwellers, displacing the dog as man’s (or

woman’s) best friend. There are now 66 million cats in US households, compared with

53 million dogs. No figures exist for Canada, but cats are no less popular in Canada.

Dr. Meyer Balter, director of the asthma education clinic at Mount Sinai Hospital in

Toronto, has stated that an amazing amount of his patients sleep with a pet sitting on

their face.

Asthmatics don’t even need to live with a cat to suffer its ill effects, notes Dr. Malcolm

Sears, a professor of medicine at McMaster University. Cat dander easily clings to the

clothing of cat owners, who can then spread it to other homes as well as offices and



5000 Canadians die annually from air pollution - the brownish or yellowish haze most

evident on warm sunny days - according to Environment Canada. The most vulnerable

are kids, because their lungs are still developing and they breathe in more air than

adults; the elderly because of the compromised immune systems; asthmatics and

others with lung disease; and anyone with heart problems.

According to the Ontario Medical Association’s report, “The Illness Costs of Air Pollution

In Ontario” (2000), smog causes 1920 deaths per year, 9800 hospital admissions,

13,000 emergency room visits, 47 million lost work days. Approximate conservative

cost estimate to the Ontario economy is $1 billion.

As many as 5 million tons of latex particles wear off tires in the United States each year.

The Denver Allergy Institute discovered that tiny black particles flake off from tires and

are thrown into the air by motorists. The latex particles have been increasingly

associated with many medical conditions such as asthma, skin rashes, etc. The

heightened irritation might explain why asthma has become increasingly prevalent and

severe since the use of radial tires, which flake off in smaller, more readily inhaled

particles than previous tires.


Poor air worsens conditions for those with allergies, asthma, lung disease and chronic

infections. Studies have shown that pollution doesn’t actually cause asthma. It just

makes a bad situation worse. People exposed to a lot of outdoor air pollution are more

likely to suffer from other lung ailments, such as chronic bronchitis. True asthma

initiators, which provoke an inflammatory condition in the lungs, tend to be some of

same things that trigger allergies. And these allergens can be found indoors -- at home

and work.

Lung disease claims close to 335,000 lives in America every year and is the third

leading cause of death in the United States.

One in 5 Canadians has some form of respiratory problem.

According to Asthma Society of Canada .....Asthma kills 500 Canadians every year.

As many as 1 in 5 children have been diagnosed with asthma.

More women than men have asthma - 8.5% of Canadian women, compared to 7.2%

men. Women’s symptoms develop later in life.

Almost twice as many women as men die from asthma, according to Statistics Canada.

Asthma can start at any age. Boys usually start wheezing on the playground, while girls

are more likely to come down with their first symptoms in their teens or early 20’s.

Asthma can also start later in life if person is exposed to a lot of smoke or chemicals at

work or home.

Only 25-40% of asthmatics ever get diagnosed.

Up to 70% of asthmatics also suffer from allergies, which can play a role in bringing on

their symptoms.

Some studies suggest that asthma rates may also be driven up by another aspect of

modern living: fewer childhood infections. Vaccines and antibiotics have been

responsible for a decline in childhood infections - and that’s a good thing. But some

researchers now suspect that many of these once-common infections played a crucial

role in training young immune systems to combat foreign microbes. Without real

microbes to fight, it’s possible the immune system may be crusading against the measly

mite and cat dander.
