Air quality in Cambodia, especially in Phnom Penh, is good during the public holiday, especially during the Water Festival, affirmed the Ministry of Environment in an announcement.
PM2.5, the atmospheric particulate matter that has a diametre of less than 2.5 micrometres, is recorded at 31.95 micrograms per cubic metre (g/m3), it added.
Air Quality Index stipulates air quality is satisfactory, and air pollution poses little or no risk if the PM2.5 is between 0-50. However, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution between 51-100.
It becomes more dangerous if the quality scale moves to between 101-150 as people with greater sensitivity can experience health impacts. In case of air quality worsen to 151-200, the condition is unhealthy, and human can start to feel it and for some people they might get ill.
