PM10 went up significantly peaking 02;00 TO 04:00 on 1 May to just over 100 µg/m³ ; not too bad for health
PM 2.5 and PM1.0 little change

How do you know it was from fireworks? Why couldn't it just be dust from Syria or one of the other usual suspects?

I have no scientific proof as to the cause. Notwithstanding, there are reasonable grounds to assume that fireworks were probably responsible for the increase in PM 10. I have never seen PM 10 to increase significantly without PM 2.5 and PM 1.0 reacting similarly. By the end of the morning the 3 PM values were more or less harmonising. I agree that this is theoretical, but, at least, it is an explanation of the observed phenomena
