Air quality in southern Singapore improved to moderate levels, with the 24-hour PSI dropping to 99 as of Oct 6, while other regions remained unhealthy.

Hourly PM2.5 readings for north and south Singapore dropped to normal levels, indicating decreased fine particle concentration.

NEA forecasts PSI to stay in high moderate to mid unhealthy range due to dry conditions and smoke from Indonesia's Kalimantan and southern Sumatra.

SINGAPORE – Air quality in the southern region of Singapore improved on the evening of Oct 6 , with the latest 24-hour Pollutant Standards Index reading there dropping from the unhealthy band to the moderate band.

The reading there at 8pm was 99, a dip from 101 an hour before.

The PSI readings for the other parts of the island remained in the unhealthy range, falling between 104 and 131.

Air quality is considered unhealthy when the 24-hour PSI – a rolling average of six key air pollutants and used in planning for outdoor activities the next day – is in the range of 101 to 200.

The hourly PM2.5 readings for the northern and southern areas also dropped to the normal band as at 8pm , at 50 and 53 respectively.

A PM2.5 reading that falls between 56 and 150 indicates an elevated concentration of fine particles in the air .

In its daily haze advisory on Oct 6, the National Environment Agency said that with the prevailing winds expected to blow from the south-east or east-south-east, the 24-hour PSI is forecast to be in the “high moderate to mid unhealthy” range.

Dry conditions are expected to persist over Kalimantan and southern Sumatra in neighbouring Indonesia, where moderate to dense smoke plumes were observed to be drifting towards Singapore.

新加坡南部空气质量改善至中等水平，截至 10 月 6 日，24 小时 PSI 降至 99，而其他地区仍处于不健康状态。

新加坡南北两地的PM2.5小时读数均已降至正常水平，表明细颗粒物浓度下降。

尼泊尔国家环境局预测，由于干燥天气以及来自印尼加里曼丹岛和苏门答腊岛南部的烟雾，空气污染指数将保持在较高、中等至中等不健康水平。

新加坡——10月6日晚，新加坡南部地区的空气质量有所改善，最新的24小时污染物标准指数读数从不健康等级降至中等等级。

晚上 8 点的读数是 99，比一小时前的 101 下降了 101。

岛上其他地区的 PSI 读数仍然处于不健康范围内，介于 104 和 131 之间。

当 24 小时 PSI（六种主要空气污染物的滚动平均值，用于规划第二天的户外活动）在 101 到 200 的范围内时，空气质量被认为是不健康的。

截至晚上 8 点，北部和南部地区的 PM2.5 小时读数也分别降至正常范围，分别为 50 和 53。

PM2.5读数在56到150之间表示空气中细颗粒物浓度升高。

国家环境局在 10 月 6 日发布的每日雾霾预警中表示，由于预计盛行风向为东南或东南偏东，24 小时 PSI 指数预计将处于“中度偏高至中度偏低”的范围内。

预计邻近的印度尼西亚加里曼丹岛和苏门答腊岛南部将持续干旱，观测到中等至浓重的烟雾正向新加坡飘去。
