Pollutant Standard Index (PSI) @ My Pharmacist House
Recently the haze topic already spam my whole facebook wall, this term – PSI keep appear in the article, it is an important air quality indicator used by Singapore to tell the public the conditions of the air around them whereas in Malaysia, we use Air Pollutant Index (API) or so called “Index Pencemar Udara” (IPU). These 2 index were similar but not identical in calculations.
These index were calculated based on the 5 major air pollutant which are CO, NO2, SO2, particulate material and ozone in the air which count on 24 hour basis (Singapore’s is based on 3 hour basis which have more reflection on real time air condition)
When inhaled these air pollutant, it will cause serious harm to our body, especially for elderly, pregnant women, children and peoples with chronic lung & heart medical conditions, you can see the impact of these air pollutant on health by visiting WHO website:
