Total particulate matter is made up of solid
and liquid particles under 100 micrometres in diameter that are
released into the atmosphere.
PM10 is the fraction of total particulate
matter that is less than or equal to 10 micrometres in diameter.
PM2.5 is the fraction of total particulate
matter that is less than or equal to 2.5 micrometres in diameter.
SOx is made up of gaseous oxides
of sulphur, mainly sulphur dioxide (SO2). In some cases, emissions
may contain small amounts of sulphur trioxide (SO3) and sulphurous
and sulphuric acid vapour.
NOx is made up of gaseous nitric
oxide (NO) and nitrogen dioxide (NO2).
Volatile organic compounds (VOCs) are made
up of photochemically reactive hydrocarbon compounds (That is those that participate
in chemical reactions when exposed to sunlight). They are major contributors
to smog in urban areas.
