It’s not a secret. (previous article here) Formaldehyde is in many types of composite, pressboard, and multidensity wood products. The EPA is now proposing to limit the amount of formaldehyde that can be added to these types of products.
When you build a structure, these types of products can offgass small amounts of formaldehyde. Even though the total formaldehyde is far less than 1% of the total product by weight/volume (which means it may NOT be listed on the SDS/MSDS- clue: look for the Prop 65 label). This can add up. The EPA is proposing to regulate the amount of formaldehyde a product can off-gas, and provide 3rd party certification framework for regulating it . 
Unfortunately, nowadays “GREEN” products/ or recycled goods can contain a lot of formaldehyde. (used in the process of making & adhering the different recycled materials together).
Expect some push back from industry. Even though it’s a known carcinogen, there is sure to be some push-back.
