SINGAPORE - The haze situation improved overnight on Oct 19, with the 24-hour PSI readings falling across the board, although in four of the five regions, the pollution levels were still classified as unhealthy.

At 6am, the Pollutant Standards Index (PSI) stood at 92 in the north, 104 in the south, 107 in the east, 139 in the west and 117 in the central region.

This is a marked improvement from the day before, when the 6am readings reached significantly higher levels: north (129), south (172), east (181), west (227) and central (185).

It also hit a new season high of 230 in the west at 10am , placing it in the “very unhealthy” band.

Meanwhile, one-hour PM2.5 readings – which measured in micrograms per cubic metre and are a gauge of the current air quality – hovered between the normal and elevated bands on Oct 19.

At 6am, the readings were: north (40), south (60), east (68), west (75) and central (75).

PM2.5 scores from 0 to 55 represent normal values, those between 56 and 150 indicate an elevated concentration of fine particles, while readings between 151 and 250 are considered high and scores above 251 are classified as very high.

The highest PM2.5 reading this haze season was recorded at 3pm on Oct 14 in the western part of the island at 288.

On Oct 18, the National Environment Agency (NEA) had forecast for Oct 19 that the PSI would lie between 101 and 190 – in the unhealthy band.

Rain is forecast over Singapore and the surrounding region on Oct 19, while winds are expected to blow from the south-south-east or south, which may limit the transport of smoke haze from Kalimantan to Singapore.

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

The haze situation on Oct 19 marks a relative easing compared to the situation last week, when PSI readings remained in the unhealthy or very unhealthy bands on most days. On Oct 16, three in five regions recorded very unhealthy PSI levels.

Singapore is currently experiencing its 15th day of unhealthy air – the longest stretch since the 2015 haze crisis, during which bad air persisted for 14 days from Sept 23 to Oct 7.

新加坡——10 月 19 日晚间，雾霾情况有所改善，24 小时空气污染指数 (PSI) 全面下降，尽管五个区域中有四个区域的污染水平仍被列为不健康。

早上 6 点，污染物标准指数 (PSI) 在北部为 92，南部为 104，东部为 107，西部为 139，中部地区为 117。

与前一天相比，情况有了显著改善，前一天早上 6 点的读数明显更高：北部（129），南部（172），东部（181），西部（227），中部（185）。

上午 10 点，西部地区的气温也达到了本季新高 230，进入了“非常不健康”的区间。

与此同时，10 月 19 日，PM2.5 一小时读数（以每立方米微克为单位测量，是衡量当前空气质量的指标）在正常和偏高水平之间徘徊。

早上 6 点，读数为：北（40），南（60），东（68），西（75），中部（75）。

PM2.5 值从 0 到 55 代表正常值，56 到 150 表示细颗粒物浓度升高，151 到 250 的读数被认为是高的，而 251 以上的分数则被归类为非常高。

本雾霾季PM2.5最高读数于10月14日下午3点在岛屿西部记录到，为288。

10 月 18 日，国家环境局 (NEA) 预测 10 月 19 日的空气污染指数 (PSI) 将在 101 至 190 之间——处于不健康范围。

预计10月19日新加坡及周边地区将有降雨，风向预计为东南偏南或正南，这可能会限制加里曼丹的烟霾向新加坡的输送。

新加坡国家环境局补充说，不过，来自苏门答腊的一些烟雾可能会飘向新加坡。

10月19日的雾霾情况较上周有所缓解，上周大部分时间空气污染指数（PSI）都处于不健康或非常不健康的水平。10月16日，五个地区中有三个地区的空气污染指数达到非常不健康的水平。

新加坡目前正经历第 15 天的空气质量不佳——这是自 2015 年雾霾危机以来持续时间最长的一次，当时从 9 月 23 日到 10 月 7 日，空气质量恶劣持续了 14 天。
