IT'S back. Smoke haze shrouded Singapore on Thursday morning, with an acrid burning smell hanging in the air. The Pollutant Standards Index (PSI) hit its first moderate level since February on Wednesday.
According to the National Environment Agency (NEA's) website, Wednesday's PSI level hit 52, falling into the moderate range (from 51 - 100).
Overall air quality has been falling over the past few months, with more days seeing moderate PSI levels in July than June.
Still, as long as air quality remains below 100 - which is in the good or moderate levels - the NEA website says citizens 'have no cause for concern'.
Meanwhile, across the causeway, Malaysia experienced the worst haze levels recorded this year, as smoke from blazing forest fires in Indonesia brought air quality range to unhealthy levels in six areas.
