“Particle mass and number measurements in a church indicate significant increases of indoor particle concentrations during the burning of incense. Generally, varying concentration regimes can be attributed to different “modes of indoor activity” and emission sources. While periods of candle burning are negligible concerning particle concentrations, increases by a factor of 6.9 and 9.1 during incense burning were observed for PM10 and PM1, respectively. At maximum, indoor PM10 shows an 8.1-fold increase in comparison to outdoor measurements. The increase of particles < 2 microm is significantly enhanced in comparison to larger particles. Due to a particle decay rate of 0.9 h(-1) post-service concentrations are elevated for a time span of approximately 24 h above indoor background concentrations.”

    This is a bunch of low church nonsense! I prefer a church with incense and I really miss it when it is absent.

    The subsequent time I read a blog, I hope that it doesnt disappoint me as much as this one. I mean, I know it was my choice to learn, but I really thought youd have one thing fascinating to say. All I hear is a bunch of whining about one thing that you may repair in case you werent too busy on the lookout for attention.
