Yeah, make sure to get a lot of ventilation, but that doesn't require any study. Even without any any pollutants, indoor air will have a bad quality. And your body deals with minor amount of bad stuff just fine.

I think that the crowd on HN tend to enjoy learning, and thus wouldn’t find it pointless to read.
