So for you faithful Indoor Air Nerd fans out there who like a little history, I’m sharing the link to this document: Indoor Air Pollutants: exposure and health effects. Click on the PDF icon labeled “Texto completo” to download it. After you open it up, you’ll want to go to page 23 (the 27th page of the PDF). There you’ll find a historical perspective on sick building syndrome. Don’t worry, it’s in English.
As an Indoor Air Nerd, I get excited about these things! Have a historical weekend!
