No, this is not possible. The health effects of such a low oxygen level would have caused mass exhaustion, headaches, symptoms such as bluing of the lips, and probably collapse among weaker citizens (source1 source2) since no such health effects were observed this cannot have occurred.

The claimed air density is about 520 times higher than air denisty now. This means that, according to the ideal gas law, you need 520 times the air pressure - roughly 520 bar. Now the critical point of nitrogen (main consituent of air) is about 33bar, the critical point of oxygen about 50 bar. Both critical temperatures are far below 0°C. So at this density,...

Esker has no evidence to support the idea of the Earths atmosphere being more dense in the Jurrasic than it is now, other than the assertion that dinosaurs are too large to have existed otherwise. However this assertion has little support, as evolutionary adaptions (such as the unidirectional breathing discussed in the previous question) are able to explain ...

I am somewhat surprised by the findings, but there is a lot of published research on this topic. A paper published in Science in 1976 maintains that: There is convincing evidence that both negative and positive ions (i) inhibit growth of bacteria and fungi on solid media; (ii) exert a lethal effect on vegetative forms of bacteria suspended in water when ...

The study "Fine Particulate Matter Emissions from Candles" (viewable online) compared various candles. It found that the beeswax candle (called BW1 in the paper) emitted less PM2.5 (often considered the worst type of common air pollution) per wick than the paraffin candles, though it emitted far more when smouldering after being extinguished. The ...
