新加坡：周二（10月6日）上午，新加坡五个地区中有四个地区的空气质量仍处于不健康范围，而南部地区在周一所有地区均录得不健康读数后，空气质量已改善至中度范围。
SINGAPORE: Air quality in four of Singapore’s five regions remained in the unhealthy range on Tuesday (Oct 6) morning, while the south improved to the moderate range after all regions recorded unhealthy readings on Monday.
截至早上6点，新加坡中部24小时污染物标准指数（PSI）读数为130，西部为117，东部为112，北部为107。新加坡南部的24小时防扩散指数为95，处于中等范围内。
As of 6am, the 24-hour Pollutant Standards Index (PSI) readings were 130 in central Singapore, 117 in the west, 112 in the east and 107 in the north. The 24-hour PSI reading in southern Singapore was 95, within the moderate range.
凌晨6点，新加坡中部、西部和东部的1小时PM2.5读数处于升高范围内，该读数提供了更新的空气质量指标。
The 1-hour PM2.5 readings, which give a more current indication of air quality, were in the elevated band in central, western and eastern Singapore at 6am.
国家环境局（NEA）表示，对于立即进行户外活动，人们应参考1小时PM2.5读数和相应的个人指南。
For immediate outdoor activities, people should refer to the 1-hour PM2.5 readings and corresponding personal guide, the National Environment Agency (NEA) said.
在计划未来24小时的户外活动时，应使用24小时防过敏指数预报和健康建议。
The 24-hour PSI forecast and health advisories should be used when planning outdoor activities for the next 24 hours.
当1小时PM2.5水平升高时，建议健康人减少接下来一小时的剧烈户外活动，而老年人、孕妇、儿童和患有慢性心肺疾病的人则应避免此类活动。
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.
在周一晚上的更新中，NEA表示，苏门答腊南部的中等至密集的烟雾羽流被观察到漂移到新加坡，而加里曼丹部分地区也观察到烟雾。
In an update on Monday evening, NEA said moderate to dense smoke plumes in the southern parts of Sumatra were observed drifting into Singapore, while smoke haze was also observed in parts of Kalimantan.
预计苏门答腊南部和加里曼丹将持续干旱。NEA说，由于预计盛行风将从东南或东南偏东方向吹来，烟雾可能继续向新加坡飘去。
Dry conditions are expected to persist over southern Sumatra and Kalimantan. With prevailing winds expected to blow from the southeast or east-southeast, smoke haze could continue to drift towards Singapore, NEA said.
NEA说，新加坡24小时的PSI预计将处于高中度至中度不健康范围。
The 24-hour PSI for Singapore was forecast to be in the high moderate to mid unhealthy range, NEA said.
24小时防污染指数是新加坡每日空气质量的指标，也是NEA每日健康宣传的基础。它是使用六种空气污染物-- PM2.5、PM10、臭氧、二氧化氮和一氧化碳--计算的，反映了过去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读数是PM2.5污染物水平的小时平均值。PM2.5是直径为2.5微米或更短的细颗粒物，是雾霾期间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.
24小时PSI读数在101至200范围内时被认为是“不健康”，在201至300范围内时被认为是“非常不健康”，超过300时被认为是“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.
每小时的PM2.5读数分为四个级别：正常，升高，高和非常高。当它在56到150之间时被认为是升高的。“高”带的范围是151至250，高于该值的读数被归类为“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".
