Bad air pollution levels have returned to Singapore and Johor in the last month. So far the recent air pollution problem has been moderate compared to June of 2013 (or Bejing). The readings have been in the “moderate” problem area but those are noticeable visually and when you are outside breathing the air is obviously more polluted than normal. I don’t usually use my air conditioning but I have the last week due to the air pollution.
The air pollution readings are published by Malaysia and Singapore. Air pollution will get a bit worse at night (assuming everything else stays the same) due to air pressure.
Air pollution has dramatic health consequences. The World Health Organization released a study last month stating that 7 million premature deaths annually are linked to air pollution.
Regionally, low- and middle-income countries in the WHO South-East Asia and Western Pacific Regions had the largest air pollution-related burden in 2012, with a total of 3.3 million deaths linked to indoor air pollution and 2.6 million deaths related to outdoor air pollution.
The damage done by air pollution to health include respiratory diseases such as asthma, cardiovascular diseases, changes in lung function. There is mounting evidence that exposure to air pollution has long-term effects on lung development in children.
With effect from 1 April 2014, Singapore has moved to an integrated air quality reporting index, where PM2.5 (particulate matter 2.5 micros or larger) will be incorporated into the current Pollutant Standards Index (PSI) as its sixth pollutant parameter. The PSI will therefore reflect a total of six pollutants – sulphur dioxide (SO2), particulate matter (PM10) and fine particulate matter (PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO) and ozone (O3).
The 3-hour PSI will take into account PM2.5 concentrations. In addition, NEA will also publish the 1-hour PM2.5 concentrations every hour.
From the Malaysian site today (their update was dated September 2013)
DOE is in the midst of finalising the new Malaysian Air Quality Guidelines to include the standard limit of PM2.5 in the ambient air which based on World Health Organisation (WHO) 2006 Guidelines.
