Air pollution
The truth behind Phnom Penh’s smoggy skies
16 May 2018

A year ago, Cambodia’s Ministry of Environment began monitoring Phnom Penh’s levels of the most damaging known air pollutant, PM2.5. Will this new knowledge be used to prevent potentially deadly air pollution, or will the ministry’s efforts prove futile?

Thiv Sophearith stands on top of the Ministry of Environment building with the sun beaming down on him. The sky is clear, aside from a thin veil of smog hovering low against the skyline.

“You can see a lot of construction sites, so [these developments] can cause the PM2.5 to be a little bit high here,” he says, pointing to a cluster of scaffolding-wrapped developments where sparks fly from saws and drills.

As chief of the ministry’s Air Quality, Noise and Vibration Office, Sophearith has spent just over a year monitoring Phnom Penh’s levels of PM2.5, the most damaging air pollutant to human health, which exists as tiny particles created from dust and burning fossil fuels. These particles can contribute to heart disease, strokes and lung illnesses such as cancer and emphysema.

The device that collects the data arrived in April last year and lives beside two acidic deposition pollution monitors on the roof of the ministry building, from which the Tonle Sap river is not much more than a coin toss away. Before this machine, there was no officially recognised monitor of the capital city’s PM2.5 air pollution, leaving the issue a mystery to all.

“Thirty-one,” says Sophearith, peering into a metal cupboard in the centre of the rooftop to read the device’s monitor. This is the most recent hourly measurement of the number of micrograms of PM2.5 particles per cubic metre of air – above the World Health Organisation’s (WHO) recommended level of 25. A pole shooting up from the cabinet absorbs the particles and quickly calculates the average amount every hour, which is then added up to find a monthly average for government records.

In March, the average rate was 29, Sophearith says – well above any of the average rates of the nine months measured last year, which jumped around between levels as low as 9.9 and as high as 19.8. “This level is not a high level,” he insists of the 31 reading.

Phnom Penh has seen worse. Data from another Phnom Penh PM2.5 monitor, at the Olympic Stadium about a ten-minute drive away, tracked by global air pollution monitoring platform AirVisual, shows a morning in early April when the level skyrocketed to 111...
