SINGAPORE – Smoke billowing from a hot spot in Johor caused slightly hazy conditions with the smell of burning in parts of Singapore on Tuesday morning (March 2), the National Environment Agency (NEA) said.
The hot spot was detected in Johor late Monday afternoon. The plume of smoke was blown by prevailing northeast winds towards Singapore before dissipating later that night.

The hourly concentration of fine particles (PM2.5) entered Band 2 (High) between 6 a.m. M. And 7 a. M. In East Singapore on Tuesday before returning to Band 1 (Normal) starting at 8am. M.
During foggy periods caused by forest fires in the region, the dominant pollutant is PM2.5.
At 11 a. M., The 24-hour Pollutant Standards Index (PSI) was 61-74, in the moderate range.
Hourly PM2.5 readings are normal when concentrations are between 0 and 55 micrograms per cubic meter of air. Readings reach elevated levels when concentrations are between 56 and 150 micrograms per cubic meter.
During elevated levels, people are advised to reduce strenuous activity outdoors, while vulnerable individuals such as the elderly, pregnant women, and children are advised to avoid strenuous activity until concentrations return to normal levels. .
