Why Buildings?
We spend 90% of our time indoors and are constantly exposed to chemicals and substances used in our built environment.
Over time, these chemicals and substances migrate into the dust that we ingest and the air that we breathe. Many construction materials, like insulation, drywall, and sealants contain toxic chemicals that can harm human health and are not good for the environment. Finishes, such as counters, flooring, and paint may also contain many toxic chemicals. Furnishings can contain many harmful chemicals including flame retardants, heavy metals, varnishes, stain-resistant coatings, endocrine disrupters, and more. Thankfully, there are healthier choices, many of which are affordable. We are dedicated to finding practical healthier options for everyone.
Common Hazards
Heavy Metals
Some metals like lead and cadmium are harmful to health, particularly to young children. The American Academy of Pediatrics says that there is no safe level of lead. However, lead is commonly found in finishes and construction materials. For example, vintage brass can contain up to 8% lead and there are even new plumbing fixtures can contain lead.
Flame Retardants
Chemical flame retardants are added to products to meet flammability standards, but often don’t improve fire safety. They are associated with impaired neurodevelopment, cancers, hormone disruption, and reproductive harm. They can be found in construction materials like insulation and furnishing like furniture foam and textiles.
PFAS
Per- and polyfluoroalkyl substances (PFAS) are used for their oil, stain, and water repellent properties. However they are associated with many harmful health effects including cancers, reproductive harm, thyroid issues, and decreased immunity. They are be found in adhesives, sealers, furnishings, and flooring.
VOCs
Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, like formaldehyde and benzene. Acute and long term health effects include eye and airway irritation, headaches, asthma, liver and kidney damage, and cancers.
Endocrine Disruptors
Endocrine disruptors are chemicals that mimic or interfere with the body’s hormones. These chemicals, including Bisphenols like BPA, and phthalates are linked with developmental, reproductive, brain, immune, and other health problems. They are commonly used to make plastics stronger or more flexible. Endocrine disruptors can be found in flooring, adhesives, sealants, piping, and many other building materials.
Other Carcinogens
There are many other probable carcinogens that are present in building materials, finishes, and furnishings. Many are restricted or phased out in Europe, but are still in use in other countries.
