SINGAPORE – The air quality here continues to improve with the hourly PM2.5 readings remaining in the normal range and the 24-hour PSI staying in the good to moderate band across the island overnight and into the morning of Oct 28.

At 6am, the one-hour PM2.5 readings were between 26 and 46, while the 24-hour PSI stood between 66 and 76 across all five regions.

PM2.5 readings are gauged hourly and reflect the current air quality. Scores from zero to 55 represent normal values, and those between 56 and 150 indicate an elevated concentration of fine particles.

Air quality is considered good to moderate when the PSI – a 24-hour rolling average of six key air pollutants – is in the range of zero to 100, and unhealthy when it is in the range of 101 to 200.

When air quality breaches the “unhealthy” threshold, people, especially the elderly, children and those with health issues, should start scaling down outdoor activities.

In its daily haze advisory on the evening of Oct 27, the National Environment Agency (NEA) said the PSI for Oct 28 is forecast to be in the good-to-moderate range of 60 to 90.

Smoke haze was observed over Kalimantan and Sumatra on Oct 27, NEA said, adding that it was dry over Singapore.

NEA said that showers are expected on Oct 28 over Kalimantan, Sumatra, Singapore and the surrounding region, which could continue to help with the haze situation.

The winds are forecast to blow from the east-northeast on Oct 28, NEA added.

For Oct 29 and 30, winds are expected to blow from the east-southeast or south-southeast.

“While this could transport smoke haze from southern Sumatra, showers are forecast over the region which should help to lower the risk of haze,” said NEA.

国家环境局表示，10 月 28 日的空气污染指数 (PSI) 预计在 60 至 90 之间，属于良好至中等水平。

新加坡——新加坡的空气质量持续改善，PM2.5 小时读数保持在正常范围内，24 小时空气污染指数 (PSI) 在 10 月 28 日夜间至早晨全岛范围内保持在良好至中等水平。

早上 6 点，五个地区的 1 小时 PM2.5 读数在 26 到 46 之间，而 24 小时 PSI 在所有五个地区都在 66 到 76 之间。

PM2.5读数每小时测量一次，反映当前的空气质量。0到55之间的数值代表正常值，56到150之间的数值则表示细颗粒物浓度升高。

当 PSI（六种主要空气污染物的 24 小时滚动平均值）在 0 到 100 的范围内时，空气质量被认为是良好到中等；当 PSI 在 101 到 200 的范围内时，空气质量被认为是不健康的。

当空气质量超过“不健康”阈值时，人们，特别是老年人、儿童和有健康问题的人，应该开始减少户外活动。

国家环境局 (NEA) 在 10 月 27 日晚间发布的每日雾霾预警中表示，预计 10 月 28 日的空气污染指数 (PSI) 将在 60 至 90 之间，属于良好至中等水平。

新加坡国家环境局表示，10月27日，加里曼丹岛和苏门答腊岛上空出现烟雾，而新加坡上空则天气晴朗。

新加坡国家环境局表示，预计10月28日加里曼丹、苏门答腊、新加坡及周边地区将有降雨，这可能有助于缓解雾霾情况。

国家环境局补充说，预计10月28日风向将来自东北偏东。

10月29日和30日，预计风向为东南偏东或东南偏南。

国家环境局表示：“虽然这可能会将苏门答腊南部的烟霾输送过来，但预计该地区将有降雨，这应该有助于降低烟霾的风险。”
