A Healthier Materials Environment at Home is important because:
There are at least 130 substances that are considered toxic to our health, many of which are in materials or are part of a production process, as outlined by The List of Toxic Substances in Schedule 1 of the Canadian Environmental Protection Act, 1999 (CEPA 1999)
We want to avoid having asbestos, mercury or lead in our homes, in which the 1978-1979 Canada Health Survey indicated that 25% of Canadians aged 6 or older had blood concentrations of the latter higher than the recommended healthy threshold (Statistics Canada, 2015)
At least 95% of all building material ingredients lack empirical data on the impact they have on human health and the environment

Being wellness-conscious with our material choices reduces our risk of bringing harmful substances into our homes.
Of particular concern are Volatile Organic Compounds (VOCs), toxic off-gassing chemicals that are found in many building materials such as “ insulation, paints, coatings, adhesives, furniture and furnishings, composite wood products and flooring materials” (WELL v2, 2018, pg. 167), and has been shown to harm our respiratory and reproductive organs, as well as cause cancer.
Furthermore, the presence of heavy metals in our household, the use of pesticides, herbicides, biocides, wood preservatives (like chromated copper arsenate, or CCA) and polychlorinated biphenyls (PCBs) in older industrial components can further compromise our health and environment.
To ensure that our material choices are not making us sick during our fight against the COVID pandemic, we must do our due diligence in researching, managing and evaluating what substances are within our indoor and outdoor environments and to eliminate and substitute them with cleaner, healthy material alternatives when possible.
Here are therefore 12 DIY Hacks for a Healthier Materials Environment at Home (from Overall Project to External Site to Interior Spaces) within a reasonable price range:
1) Overall Project: Consider the Three Pillars of Sustainability
The three pillars of Sustainability are generally regarded as the Social, the Environmental and the Economic spheres.
When considering materials and products, it is therefore important to balance the health and wellness benefits that they bring, as well as how these three pillars impact our interior spaces, the architecture, the planning of cities, and our planet.
2) Overall Project: Ban the use of Lead, Asbestos, & Mercury
Lead*, Asbestos**, and Mercury*** are three of the most hazardous ingredients to human health and were once prominently used in the AEC industry as building materials and products (i.e. plumbing and paints, fireproofing, and lamps, respectively).
After their ban or proposed ban in Canada in 1976, 1979, and 2011 respectively, the federal government has severely limited their use in both exterior and interior products due to their harmful effect on human health upon exposure.
Lead and Asbestos slowly phased out in favour for more healthier material and product alternatives, with Mercury in the process of following suite.
3) Overall Project: Lead, Asbestos and PCB Abatement Strategy
If your house was built before the 1960s in Canada, and you are planning to renovate or demolish parts of it, consider the following information:
Homes during this era are likely to contain hazardous traces of lead in old paint, asbestos for heat resistance and fireproofing materials, and PCBs (Polychlorinated biphenyl)**** in old industrial components, such as sealants, caulking, oils, paints, lubricants, and coolants.
Despite their uses, Lead has been shown to cause anemia and neurological defects in young children; Asbestos can cause mesothelioma, a respiratory cancer in which the lungs’ linings get filled with fiber when it is inhaled; and PCBs which can adversely affect our “immune system, reproductive system, nervous system, endocrine system and other health effe
