What are we measuring?

Total Suspended Particles(TSP),

PM10, PM2.5, Wind Speed,

Direction and other weather

parameters

When did we start?

17th October 2014

For practical ambient air quality work, we generally recognise three

categories or fractions of particulate matter (“PM”):

Total Suspended Particulates (TSP) –full range of particle sizes,

including those larger than 10 micrometres that cannot pass the

nose and throat (ranging up to 50-100 micrometres*).

PM10 – all particles less than or equal to 10 micrometres, which can

enter the lungs

PM2.5 – all particles less than or equal to 2.5 micrometres. Penetrate

into the deepest areas of the lungs. (A subset of the PM10 fraction)

*Micrometre is one millionth of a metre
