Interesting that the fire in the fireplace seemed to have no effect. This post gives a pessimistic estimate of 25,000 (pm2.5 I believe) in worst possible conditions and 2-3 orders of magnitude better (25-250?) under ideal conditions. Interesting that you found essentially no effect. Maybe good conditions/a flue with good draw reduces it to essentially zero?
It seems like your measurements for the candles match theirs as well “a spike to around 50-200 with particles hang in the air for 3-5 hours”. Obviously, an airtight lid (as they suggest) is not possible for Hanukkah candles (or the matches themselves), but I would be curious to see how running them under water or using a snuffer changes things (or just taking them outside to blow them out).
I’d also be curious to see how different types of lighters perform vs matches. I would guess that any type of lighter would be a lot better, but perhaps running the matches under water to extinguish them would be almost as good—though I would guess that a significant portion of their emissions comes from just lighting them.
