SINGAPORE: Air quality in Singapore was mostly unhealthy on Monday (Oct 19), with the 24-hour Pollutant Standard Index (PSI) ranging from 92 at a moderate level in the north to 139 at an unhealthy level in the west.

Hourly PM2.5 readings were elevated in the western, central, southern and eastern regions.

Singapore's air quality remained in the unhealthy band across most regions throughout Sunday. The country's west, the only outlier, was in the very unhealthy range from 8pm on Saturday and only joined the other regions at 5pm on Sunday.

At 10am, its 24-hour PSI hit 230 - marking a new high for this year's haze season.

Showers are forecast over Singapore and the surrounding region for Monday, with winds expected to blow from the south-southeast or south, which may limit smoke haze from Kalimantan to Singapore, said the agency.

However, some smoke haze from Sumatra may drift towards Singapore, it added.

Smoke haze moving from Kalimantan to Singapore could also decrease on Tuesday due to forecast southeasterly or southerly winds, as well as expected showers surrounding Singapore.

"However, the winds are likely to turn east-southeasterly from Tuesday night, which may bring smoke haze from fires in Kalimantan towards Singapore overnight," said NEA.

ADVICE FOR VULNERABLE GROUPS

NEA advises the elderly, pregnant women and children to minimise prolonged or strenuous outdoor physical exertion when the 24-hour PSI is in the unhealthy range.

Those with chronic diseases, as well as lung or heart diseases, should avoid such activities during unhealthy air quality.

For deciding whether to wear a mask during immediate outdoor activities, the public is advised to refer to the hourly PM2.5 readings instead.

When the 1-hour PM2.5 readings are in the high band, vulnerable individuals, including the elderly, pregnant women and those with chronic heart or lung conditions, should avoid outdoor activities, according to the Ministry of Health (MOH).

Those who need to go outdoors for immediate activities may wear a well-fitting N95 mask or equivalent to reduce their exposure to haze particles.

When PM2.5 readings reach the very high band of 251 and above, healthy individuals should also minimise all outdoor activities. Those who need to venture outdoors may similarly use an N95 mask for protection.

The ministry has also advised the elderly, pregnant women and those with severe heart or lung conditions who experience breathing difficulties to consult their doctor before using an N95 mask.

Those who experience discomfort while wearing one should take a break from using it.

Besides N95 masks, KN95, FFP2 and KF94 masks are also effective in reducing exposure to haze particles, according to MOH.

新加坡：周一（10 月 19 日），新加坡大部分地区的空气质量都不健康，24 小时污染物标准指数 (PSI) 从北部的 92（中等水平）到西部的 139（不健康水平）不等。

西部、中部、南部和东部地区的PM2.5小时读数均偏高。

周日，新加坡大部分地区的空气质量仍处于不健康水平。只有西部地区例外，该地区从周六晚上8点起就处于非常不健康水平，直到周日下午5点才与其他地区一样。

上午 10 点，该地区的 24 小时 PSI 值达到 230，创下今年雾霾季的新高。

国家环境局（NEA）在周日晚间的公告中表示，预计周一的24小时空气污染指数（PSI）将处于不健康范围，介于101至190之间。

该机构表示，预计周一新加坡及周边地区将有阵雨，风向预计为东南偏南或正南风，这可能会限制加里曼丹岛的烟雾扩散到新加坡。

报告还指出，苏门答腊岛的一些烟雾可能会飘向新加坡。

受预计的东南风或南风以及新加坡周边地区预计的阵雨影响，周二从加里曼丹吹向新加坡的烟霾可能会减少。

“然而，从周二晚上开始，风向可能会转为东南风，这可能会在夜间将加里曼丹岛火灾产生的烟雾带到新加坡，”国家环境局表示。

给弱势群体的建议

新加坡国家环境局建议老年人、孕妇和儿童在 24 小时 PSI 指数处于不健康范围内时，尽量减少长时间或剧烈的户外体力活动。

患有慢性疾病以及肺部或心脏疾病的人，在空气质量不佳时应避免进行此类活动。

对于决定在进行户外活动时是否佩戴口罩，建议公众参考每小时的 PM2.5 读数。

根据卫生部 (MOH) 的说法，当 1 小时 PM2.5 读数处于高位时，包括老年人、孕妇和患有慢性心脏或肺部疾病的人在内的弱势群体应避免户外活动。

那些因紧急情况需要外出的人可以佩戴贴合度良好的 N95 口罩或同等防护等级的口罩，以减少接触雾霾颗粒。

当PM2.5浓度达到251及以上（极高水平）时，健康人群也应尽量减少户外活动。必须外出的人群同样可以佩戴N95口罩进行防护。

该部还建议老年人、孕妇以及患有严重心脏或肺部疾病且出现呼吸困难的人在使用 N95 口罩前咨询医生。

如果佩戴时感到不适，应暂停使用。

卫生部表示，除了 N95 口罩外，KN95、FFP2 和 KF94 口罩也能有效减少接触雾霾颗粒。
