新加坡：周四（10月8日），新加坡所有五个地区空气质量均处于不健康范围，西部地区在早上6点记录到24小时污染物标准指数（PSI）为161。
SINGAPORE: Air quality across all five regions of Singapore remained in the unhealthy range on Thursday (Oct 8), with the west recording a 24-hour Pollutant Standards Index (PSI) reading of 161 at 6am.
周三中午，新加坡各地的24小时PSI读数进入不健康范围，并持续至周四早晨。
The 24-hour PSI readings entered the unhealthy range across Singapore at noon on Wednesday and remained there overnight into Thursday morning.
截至早上6点，新加坡中部的24小时PSI为147，东部为128，南部为120，北部为113。
As of 6am, the 24-hour PSI was 147 in central Singapore, 128 in the east, 120 in the south and 113 in the north.
1小时PM2.5读数在新加坡中部和西部地区处于偏高水平，而北部、南部和东部则处于正常水平。
The 1-hour PM2.5 readings were in the elevated band in central and western Singapore, while readings in the north, south and east were in the normal band.
周三下午4点，西部地区的1小时PM2.5读数升至152，首次进入本烟雾季的“高”水平范围，但一小时后又回落至偏高水平。
On Wednesday, the 1-hour PM2.5 reading in the west rose to 152 at 4pm, entering the "high" band for the first time this haze season, before falling back into the elevated band an hour later.
周三晚间，国家环境局（NEA）在一份通告中表示，观察到来自苏门答腊南部的中度至浓密烟雾云团正向新加坡漂移。此外，加里曼丹地区的热点也出现了中度至浓密的烟雾。
In an advisory on Wednesday evening, the National Environment Agency (NEA) said moderate to dense smoke plumes from southern Sumatra were observed drifting towards Singapore. Moderate to dense smoke haze was also observed from hotspots in Kalimantan.
预计苏门答腊中部和南部以及加里曼丹大部分地区将持续干燥。国家环境局指出，在当前的东南至南风影响下，这些地区的烟雾可能继续向新加坡漂移。新加坡的24小时PSI预计将仍处于不健康范围。
Dry conditions are expected to continue over central and southern Sumatra and many parts of Kalimantan. Under the prevailing southeasterly to southerly winds, smoke haze from these areas may continue to drift towards Singapore, NEA said. The 24-hour PSI for Singapore is forecast to be in the unhealthy range.
在规划未来24小时的户外活动时，公众建议参考24小时PSI预报和健康提示。
When planning outdoor activities for the next 24 hours, the public is advised to use the 24-hour PSI forecast and health advisories.
当1小时PM2.5水平偏高时，建议健康人群在未来一小时内减少剧烈户外活动，而老年人、孕妇、儿童以及患有慢性心脏病或肺病的人群则应避免此类活动。
When 1-hour PM2.5 levels are elevated, healthy people are advised to reduce strenuous outdoor activity for the next hour, while the elderly, pregnant women, children and people with chronic heart or lung conditions should avoid such activity.
24小时PSI是新加坡每日空气质量的指标，也是新加坡环境局（NEA）每日健康建议的基础。该指数通过六种空气污染物——PM2.5、PM10、臭氧、二氧化硫、二氧化氮和一氧化碳——计算得出，反映过去24小时的平均空气质量。
The 24-hour PSI is Singapore's indicator of daily air quality and forms the basis of NEA's daily health advisories. It is calculated using six air pollutants - PM2.5, PM10, ozone, sulphur dioxide, nitrogen dioxide and carbon monoxide - and reflects the average air quality of the past 24 hours.
另一方面，1小时PM2.5读数则是PM2.5污染物浓度的每小时平均值。PM2.5是指直径为2.5微米或更小的细颗粒物，是雾霾天气中对健康造成危害的主要污染物。
The 1-hour PM2.5 reading, on the other hand, is the hourly average of the PM2.5 pollutant levels. PM2.5 is fine particulate matter with a diameter of 2.5 micrometres or shorter, and is the dominant pollutant during haze that causes harm to health.
当24小时PSI读数处于101至200之间时，被视为“不健康”；在201至300之间时，被视为“非常不健康”；超过300时，则被视为“危险”。
A 24-hour PSI reading is considered "unhealthy" when it is in the 101 to 200 range, "very unhealthy" when it is within the 201-300 range and "hazardous" when it goes over 300.
每小时PM2.5读数分为四个等级：正常、偏高、高和非常高。当读数在56至150之间时，被视为“偏高”；“高”等级的范围是151至250；高于该范围的读数则被归类为“非常高”。
The hourly PM2.5 reading is classified in four bands: normal, elevated, high and very high. It is considered elevated when it ranges from 56 to 150. The "high" band ranges from 151 to 250, and readings above that are classified as "very high".
