SINGAPORE - Residents are enjoying clear skies again as Sunday began with the 24-hour Pollutant Standards Index (PSI) in the moderate range.

The better air conditions have persisted into mid-day, with the 24-hour PSI, a measure of air quality here, at 12pm standing at between 66 and 76.

The National Environment Agency has forecast that the 24-hour PSI to be in the high-end of the moderate range (51 to 100) and low-end of the unhealthy range (101 to200) on Sunday.

But if the haze does return, those living on Pulau Ubin will be well-equipped with haze protection kits to protect themselves from the air pollutants.

The WeCare Packs contain items such as N95 masks, lozenges, vitamin C tablets and food items such as instant noodles and canned sardines.

Dr Maliki Osman, Minister of State for National Development and Defence, together with volunteers from Siglap grassroots organisations, distributed the packs to seven households and three shops on the island on Sunday morning.

Madam Huang Ya Shan, 77, who received a WeCare Pack, said she is thankful for the items.

"It shows they care or they wouldn't have come all the way to give it to me personally," said the drink stall owner.

Most households have already received N95 masks from the Siglap grassroots leaders, and those who have not will get them in the coming days.

Currently, 30 residents, mostly old folk, live permanently on the small island to the north-east of the main Singapore island.

Dr Maliki said: "We are very concerned about the haze situation and how our pioneers who are living alone are managing on their own here. Over the last couple of days, I've sent my grassroots leaders to give them masks first, and today we visited them again to see how else we can support and help them."

A mask collection point has also been set up at a bicycle shop near the jetty, run by the village chief, Mr Chu Yok Choon, 70.
