How have Malaysia's PM2.5 and PM10 concentrations moved over time?

Annual averages calculated from DOE's published monthly national particulate concentrations.

Method & notes

IN BRIEF

This view keeps only PM2.5 and PM10, which share the same concentration unit.

METHOD & LIMITATIONS

How the numbers were calculated

PulseKita averages the available monthly national PM2.5 and PM10 concentration values within each calendar year. Only particulate pollutants are compared because both use µg/m³; gaseous pollutants reported in ppm are deliberately excluded from this chart.

This is an average of published monthly concentrations, not a population-weighted exposure estimate.
Missing monthly observations are excluded from that year's arithmetic mean rather than filled with zero.
PM2.5 and PM10 are comparable in unit but represent different particle-size fractions.
PulseKita does not mix CO, NO2, O3 or SO2 into this chart because their source unit is ppm.
