Air quality in Singapore improved slightly, but the haze stayed in the “unhealthy” range across the island.

At 7am on Oct 11, PSI readings were 116 to 153, down from a peak of 183 in the central region the day before.

NEA said haze from southern Sumatra and Kalimantan will keep drifting towards Singapore, with PSI forecast in the “unhealthy to high unhealthy range”.

SINGAPORE - The haze situation here eased slightly overnight even as the air quality across the island remained in the unhealthy range.

At 7am on Oct 11, the 24-hour Pollutant Standards Index (PSI) readings stood at 119 in the north, 116 in the south, 140 in the east, 153 in the west and 153 in the central region.

This marks a slight improvement from a day before when the PSI value peaked at 183 in the central region at midnight before gradually dropping throughout the day.

Air quality is considered unhealthy when the PSI – a 24-hour rolling average of six key air pollutants – is in the range of 101 to 200.

Meanwhile, the PM2.5 reading remained in the elevated range across Singapore - 56 in the north, 64 in the south, 103 in the east, 108 in the west and 101 in the central region.

The hourly PM2.5 reading is used as a gauge for immediate air quality, with scores from 56 to 150 indicating elevated pollution levels while values of 151 to 250 represent high pollution levels.

In its daily advisory issued at 7pm on Oct 10, the National Environment Agency (NEA) said the 24-hour PSI is forecast to be in the “unhealthy to high unhealthy range”, staying out of the “very unhealthy” range of 201 to 300.

“Moderate to dense smoke haze from southern Sumatra was observed to drift towards Singapore. Smoke haze was also observed in many parts of Kalimantan,” it noted.

It added that the haze will continue to drift towards Singapore under prevailing east-south-easterly or southerlywinds.

新加坡的空气质量略有改善，但全岛的雾霾仍然处于“不健康”范围。

10 月 11 日上午 7 点，PSI 读数为 116 至 153，低于前一天中部地区 183 的峰值。

新加坡国家环境局表示，来自苏门答腊南部和加里曼丹的雾霾将继续向新加坡飘来，预计空气污染指数将处于“不健康至高度不健康”的范围内。

新加坡——尽管全岛空气质量仍处于不健康水平，但此地的雾霾情况一夜之间略有缓解。

10 月 11 日上午 7 点，24 小时污染物标准指数 (PSI) 读数北部为 119，南部为 116，东部为 140，西部为 153，中部地区为 153。

这比前一天略有改善，前一天午夜时分，中部地区的 PSI 值达到峰值 183，之后在一天内逐渐下降。

当 PSI（六种主要空气污染物的 24 小时滚动平均值）在 101 到 200 之间时，空气质量被认为是不健康的。

与此同时，新加坡各地的 PM2.5 读数仍然处于较高水平——北部 56，南部 64，东部 103，西部 108，中部地区 101。

每小时 PM2.5 读数被用作衡量即时空气质量的指标，56 至 150 的分数表示污染水平升高，而 151 至 250 的值表示污染水平极高。

国家环境局 (NEA) 在 10 月 10 日晚上 7 点发布的每日公告中表示，预计 24 小时空气污染指数 (PSI) 将处于“不健康至高度不健康”的范围内，不会进入 201 至 300 的“非常不健康”范围。

报告指出：“来自苏门答腊南部的中度至重度烟霾向新加坡飘移。加里曼丹许多地区也观测到了烟霾。”

报告还指出，在盛行的东南风或南风的影响下，雾霾将继续向新加坡方向飘移。
