Air Pollution in Singapore
Pollution is always a concern to people, and air pollution is something people are more concerned about since you cannot selectively breath in air (whereas you can filter water or even buy imported mineral water).
Amongst air pollutants, sulfur dioxide is a major source of acid rain. While emissions are controlled under the government's regulation, it is interesting to note that more than half of our country's sulfur dioxide emissions come from three companies that run the refineries in Singapore.
Yes, the three refineries in Singapore belch out 51% of Singapore's sulfur dioxide. The power plants cough out another 27% and ships another 18%. This means that all other industries and modes of transport only contribute the residual 4%, or about 5000 tons.
Well, that is as much as NEA lets us know about air pollution. No statistics on carbon monoxide or nitrogen oxides is given, nor is there a record of particulate matter published (outside the incidences when we are shrouded by the haze). Even then, we only get the PM10 numbers, and not the PM2.5. Isn't it time that we start publishing this data?
