There's lots of toxins in our environment...and lots of misinformation on the internet and elsewhere, about them...especially the ones found in building materials. Air quality can be affected by VOCs (Volitile Organic Compounds).
"Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects." https://www.epa.gov/…/volatile-organic-compounds-impact-ind…
In manufactured wood products, the biggest concern is urea formaldehyde. This is often found in highly processed, interior wood products. It is NOT usually found in engineered structural wood building materials, despite common misinformation to the contrary.
This table, published in the APA Technical Note: Formaldehyde and Engineered Wood Products #J330 summarizes North American engineered wood products. Note Urea Formaldehyde is not found in these structural wood products.
This document is also relevant on the topic of Formaldehyde. Note the emphasis on interior and hardwood engineered wood products containing Urea Formaldehyde.
