Several places in Malaysia & its neighboring countries, like Singapore, Indonesia, are under the attack of serious smog. In Singapore, a record of 371 of Air Pollution Index (API) has been reported. In Malaysia couple places also reported API over 300 today, like Pasir Gudang and Kota Tinggi in Johor both reported 310 and 314, respectively.
So, what is API? API is an index to measure the quality of air. Pollutants that accounted in the index are sulfur dioxide (SO2), nitrogen dioxide (NO2), suspended particulates (PM2.5 & PM10), carbon monoxide (CO), and ozone (O3).
So, what does API number mean?
My city, Kota Kinabalu, also not spared. Even the API level is still within "Moderate" this morning but looking out far things are getting blurred.
So, better to stay indoor, drink a lot of water and Chinese herbal teas. Stay healthy!
