SINGAPORE – The air quality in Singapore improved marginally overnight but still remained within the unhealthy band on the 24-hour Pollutant Standards Index early on Oct 10.<\/p>\n

At 7am, the PSI readings were: north (125), south (141), east (157), west (162), central (176).<\/p>\n

Air quality is considered unhealthy when the PSI – a 24-hour rolling average of six key air pollutants – is in the range of 101 to 200.<\/p>\n

PM2.5 readings, which point to the current air quality and are used as a gauge for immediate activities, were also elevated in all five regions: north (69), south (89), east (112), west (104), central (124).<\/p>\n

An hourly PM2.5 reading between 56 and 150 indicates an elevated concentration of fine particles.<\/p>\n

The PSI had hit a high for the year on Oct 9<\/span><\/a>, reaching 192 on the PSI in the central region between 5pm and 8pm.<\/p>\n

In its Oct 9 daily advisory, the National Environment Agency (NEA) had forecast the PSI for Oct 10 to lie in the \u201cunhealthy to low very unhealthy range\u201d.<\/p>\n
