Want clean air this today? Skip Pasir Gudang, head for Balik Pulau or Limbang

As of October 18, Pasir Gudang in Johor is experiencing unhealthy air quality with an Air Pollutant Index (API) of 191, nearing the very unhealthy threshold.

Other areas in Johor, as well as parts of Negeri Sembilan, Selangor, Melaka, and Kuala Lumpur, also report high API levels, indicating deteriorating air quality.

Conversely, Balik Pulau in Penang and Limbang in Sarawak continue to enjoy good air quality, showcasing significant regional disparities in air conditions across Malaysia.

Most regions in East Malaysia and other states maintain moderate API readings.

KUALA LUMPUR, Oct 18 — The worst place to be in Malaysia right now is Pasir Gudang in Johor, where the Air Pollutant Index (API) stood at 191 at 10am, according to the Department of Environment’s Air Pollutant Index Management System portal.

That is unhealthy air, just nine points shy of the “very unhealthy” line at 201, which the Johor industrial town crossed yesterday with a reading of 203.

It also edged up from 190 at 8am.

Now pick the best place, and the story flips: Balik Pulau in Penang recorded 42 at 10am, less than a quarter of Pasir Gudang’s reading.

Limbang in Sarawak was not far behind at 48, and both were firmly in the “good” range.

Between them lies a country breathing very differently, and the picture is clearest state by state.

Johor was again the hardest hit, with Kota Tinggi at 183, Larkin at 181, Pengerang at 178 and Batu Pahat at 168 trailing Pasir Gudang.

Negeri Sembilan came next, where Nilai recorded 171, Seremban 167 and Port Dickson 151.

In Selangor, Johan Setia led at 164, followed by Shah Alam (160), Klang (157), Petaling Jaya (156) and Banting (155).

Yet Kuala Selangor, further north in the same state, managed a moderate 84.

Melaka was not spared, with Bukit Rambai at 163, Alor Gajah at 160 and Bandaraya Melaka at 155.

Putrajaya logged 158, while in Kuala Lumpur, Cheras recorded 156 and Batu Muda 155.

East Malaysia fared better, though Sandakan in Sabah still hit 152.

In Sarawak, Sri Aman was just over the unhealthy line at 105.

Elsewhere, Labuan and the rest of Penang, Kedah, Kelantan, Perlis, Terengganu, Pahang and Perak stayed in the moderate range.

Readings between 0 and 50 are classified as good, 51 to 100 as moderate, 101 to 200 as unhealthy, 201 to 300 as very unhealthy and above 300 as hazardous.

截至 10 月 18 日，柔佛州巴西古当的空气质量不健康，空气污染指数 (API) 为 191，接近非常不健康的阈值。

柔佛州的其他地区，以及森美兰州、雪兰莪州、马六甲和吉隆坡的部分地区，API 水平也很高，表明空气质量正在恶化。

相反，槟城的浮罗山背和砂拉越的林梦空气质量依然良好，这表明马来西亚各地空气状况存在显著的区域差异。

东马来西亚大部分地区和其他州的API读数保持在中等水平。

吉隆坡，10 月 18 日讯——根据环境部空气污染指数管理系统门户网站的数据，目前马来西亚空气污染最严重的地方是柔佛州的巴西古当，上午 10 点的空气污染指数 (API) 为 191。

空气质量不健康，距离“非常不健康”的201线仅差9个点，而柔佛州的这座工业城镇昨天的读数达到了203，超过了201线。

早上 8 点时，该数值也从 190 略微上升。

现在选择最佳地点，情况就完全不同了：槟城浮罗山背上午 10 点记录到 42 次，不到巴西古当记录的四分之一。

砂拉越的林邦紧随其后，得分为 48 分，这两个分数都稳居“良好”范围。

它们之间横亘着一个呼吸方式截然不同的国家，而逐个州来看，情况则最为清晰。

柔佛州再次成为重灾区，哥打丁宜（183）、拉金（181）、边佳兰（178）和峇株巴辖（168）落后于巴西古当（Pasir Gudang）。

其次是森美兰州，汝来录得 171 架，芙蓉 167 架，波德申 151 架。

在雪兰莪州，Johan Setia以164分领先，其次是莎阿南（160分）、巴生（157分）、八打灵再也（156分）和万津（155分）。

然而，同属一个州的北部城市瓜拉雪兰莪却取得了中等水平的84度。

马六甲也未能幸免，武吉兰拜 (Bukit Rambai) 排名第 163，亚罗牙也 (Alor Gajah) 排名第 160，马六甲城 (Bandaraya Melaka) 排名第 155。

布城录得 158 起，而吉隆坡、蕉赖和峇都慕达则分别为 156 起和 155 起。

东马表现较好，但沙巴山打根仍达到 152。

在砂拉越，斯里阿曼的血糖水平刚好超过不健康线，为 105。

在其他地方，纳闽和槟城、吉打、吉兰丹、玻璃市、登嘉楼、彭亨和霹雳州的其他地区保持在中等范围。

读数在 0 到 50 之间为良好，51 到 100 之间为中等，101 到 200 之间为不健康，201 到 300 之间为非常不健康，300 以上为危险。
