    • From the January 4th, 2008 Oprah Show


      Seventh Generation products, which are found in health food stores, Whole
      Foods, Target and online, are also nontoxic. "What I love about them is they're all
      made without dyes, without perfumes," Simran says. "All the cleaning agents are
      plant-based instead of petroleum-based."

      Mrs. Meyer's Clean Day is another company that specializes in cleaners made
      with ingredients like corn, sugar cane, coconut and palm. This company, which
      was named after the founder's mother, also sells nontoxic products for pets.
      To make your chores even more environmentally friendly, Simran suggests using
      microfiber cloths from a company like Method to apply the products to your
      furniture, counters and sinks. These cleaning cloths are machine washable and

      Even if these products are more expensive that traditional cleaners, Simran says
      the health benefits may be worth the cost. In some areas of the country, the air
      quality inside the home is twice as dangerous as the air outside the home,
      according to the EPA.

      "The reason is because of, in part, cleaning products, the paints that we
      have on our walls, varnishes on our furniture, the formaldehydes and glues
      in our carpet," Simran says. "You're creating this little chemical cocktail
      you're breathing in all the time."

    • Indoor Air Pollution Fact Sheet


      Air pollution contributes to lung disease, including respiratory tract infections,
      asthma, and lung cancer. Lung disease claims close to 335,000 lives in America
      every year and is the third leading cause of death in the United States. Over the last
      decade, the death rate for lung disease has risen faster than for almost any other
      major disease.

      • Poor indoor air quality can cause or contribute to the development of chronic
      respiratory diseases such as asthma and hypersensitivity pneumonitis. In
      addition, it can cause headaches, dry eyes, nasal congestion, nausea and
      fatigue. People who already have respiratory diseases are at greater risk.
      • Biological pollutants, including molds, bacteria, viruses, pollen, dust mites,
      and animal dander promote poor indoor air quality and may be a major cause
      of days lost from work and school. In office buildings, heating, cooling, and
      ventilation systems are frequent sources of biological substances that are
      inhaled, leading to breathing problems.
      • To help prevent growth of mold when humidity is high, make sure bathrooms,
      kitchens and basements have good air circulation and are cleaned often. The
      basement in particular may need a dehumidifier. And remember, the water in
      the dehumidifier must be emptied and the container cleaned often to prevent
      forming mildew.
      • An estimated one out of every 15 homes in the United States has radon levels
      above 4pci/L, the U. S. Environmental Protection Agency-recommended
      action level. Radon, a naturally occurring gas, can enter the home through
      cracks in the foundation floor and walls, drains, and other openings. Indoor
      radon exposure is estimated to be the second leading cause of lung cancer. A
      recent report by the National Research Council estimates that radon is
      responsible for between 15,000 and 21,000 lung cancer deaths each year in
      the United States.
      • Environmental tobacco smoke (ETS) also called "secondhand smoke," a major
      indoor air pollutant, contains about 4,000 chemicals, including 200 known
      poisons, such as formaldehyde and carbon monoxide, as well as 43
      • ETS causes an estimated 3,000 lung cancer deaths and 35,000 to 50,000
      heart disease deaths in non-smokers, as well as 150,000 to 300,000 cases of
      lower respiratory tract infections in children under 18 months of age each
      • Formaldehyde is a common chemical, found primarily in adhesive or bonding
      agents for many materials found in households and offices, including carpets,
      upholstery, particle board, and plywood paneling. The release of
      formaldehyde into the air may cause health problems, such as coughing; eye,
      nose, and throat irritation; skin rashes, headaches, and dizziness.
      • Asbestos is the name given to a group of microscopic mineral fibers that are
      flexible and durable and will not burn. Asbestos fibers are light and small
      enough to remain airborne; they can be inhaled into the lungs and can cause
      asbestosis (scarring of the lung tissue), lung cancer and mesothelioma, a
      relatively uncommon cancer of the lining of the lung or abdominal cavity.
      • Many asbestos products are found in the home, including roofing and flooring
      materials, wall and pipe insulation, spackling compounds, cement, coating
      materials, heating equipment, and acoustic insulation. These products are a
      potential problem indoors only if the asbestos-containing material is disturbed
      and becomes airborne, or when it disintegrates with age.
      • Heating systems and other home appliances using gas, fuel, or wood, can
      produce several combustion products, of which the most dangerous are
      carbon monoxide (CO) and nitrogen dioxide (NO2). Fuel burning stoves,
      furnaces, fireplaces, heaters, water heaters, and dryers are all combustion
      • Carbon monoxide is an odorless, colorless gas that interferes with the
      distribution of oxygen to the body. Depending on the amount inhaled, this gas
      can impede coordination, worsen cardiovascular conditions, and produce
      fatigue, headache, confusion, nausea, and dizziness. Very high levels can
      cause death.
      • Nitrogen dioxide is a colorless, odorless gas that irritates the mucous
      membranes in the eye, nose and throat and causes shortness of breath after
      exposure to high concentrations. Prolonged exposure to high levels of this gas
      can damage respiratory tissue and may lead to chronic bronchitis.
      • Household cleaning agents, personal care products, pesticides, paints, hobby
      products, and solvents may be sources of hundreds of potentially harmful
      chemicals. Such components in many household and personal care products
      can cause dizziness, nausea, allergic reactions, eye/skin/respiratory tract
      irritation, and cancer.
