Perhaps you are just a simple software developer, but there are plenty of people here who are genuine experts in every field imaginable: I have had intelligent discussions here with everyone from neuroscientists to microbiologists to carpenters to machinists.
More to your point, I think the modern idea that people must stay confined to their specialty is ridiculous. Not long ago it was common to have intelligent discussions - or do serious work - on topics where you had no formal education or experience. All of that occurred without the internet. Look at the early days of, for example, the Manhattan Project. Not a trivial undertaking, and yet many of the men did countless tasks where they had zero training or experience. Look at the history of any scientific field or large engineering project. For all of human history that is how it was: and now if you want to replace a toilet valve, or a lightswitch, or comment about a scientific topic, you must hire someone with the appropriate credentials.
Back to my point - as a matter of fact I do have a professional perspective on the question of indoor air pollutants. Perhaps not the credentials you seek, nevertheless: I develop consumer products for the home, and levels of indoor air pollutants are now high enough - due to precisely the causes I originally mentioned - that they are beginning to cause nasty interactions that destroy the products of my industry via fouling and corrosion. In fact, the professional associations for my industry have written extensively about the scale of the problem and several companies have invested significantly in R&D to identity solutions. In other words, the air we breathe is damaging the things around us; could it not damage our lungs as well? I do not make any absolute statements, but I think a serious discussion should be had and I see no reason that it shouldn’t also happen on HN.
