    I need one of those counters... I’d be super curious to know the readings from in the London tube... I bet it is insanely bad in all three measures...

      Ha, they say one hour on the Tube is like smoking a cigarette. I notice a big difference between the old trains and the newer ones. But it's the price we pay to be cosmopolitan.

      Savvas Papasavva it has to be worse... If I clean my nostrils with a piece of paper after a 30/40 min trip it comes out full of black powder(sorry it’s gross I know) but I do it every time...

      Lol. but it's true though. It's probably not much different from being in a metal workshop in some respects. I think cycling in London must be worse - behind all those vehicles. At least you catch some soot and dust in your nose, but the fumes!!! Anyway there's initiatives to improve the air quality so hopefully things improve.

    Hello sir,
    I am having airborne dust concentrations data as PM10, PM2.5, PM 1 .
    These data was taken before and during dust producing work in a civil construction site.
    N=5
    How can i compare these before and during operations data ?
    It seems that there is percent variation in dust concentrations in atmosphere between before and during operation data.
    e.g., PM 10 ( particle size less than 10 microns) is sharing 40% of total airborne dust, and PM 2.5 ( particle size less than 2. 5 micron) shares 10% of total airborne dust.
    During machine operation:
    PM 10 shares 60% and PM 2.5 10% only.
    It seems that PM 10 share is increased due to that machine operation?
    Which test is suitable for analysing these type similar data for discussion ?
    How to use statistics?
    Any comparison among these particle sizes?
    thank u.

    Any follow up details? Is it still good? Have you compared it with anything else?

    Do you try to compare it to the calibrated one?

      I think I'd picked the day to film when all the trees in London released their pollen at the same time. Lol.
