Please demonstrate the TSI SMPS.. Dada analysis in concern of particle formation and its growth rate

Do you have any idea why your mass concentrations in the different sizes looks so similar?

Hello

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.
