Air quality in Taiwan is measured according to the Air Quality Index (AQI). The AQI measures for sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone and other particulates (PM10 and PM2.5). 台灣空氣品質是用空氣品質指標 (AQI)來測量。 空氣品質指標測量的內容是二氧化硫、二氧化氮、 二氧化碳、臭氧還有PM10跟PM2.5.
An AQI of 0-50 is seen as "good," 51-100 is "moderate," 101-150 is "unhealthy for sensitive groups," 151-200 is "unhealthy" and 201-250 is "very unhealthy." When the AQI reading approaches 300, governments start telling people to stay indoors and avoid strenuous exercise outdoors. 0-50AQI是 "優"， 51-100是 "良"， 101-150是 "輕度污染"， 151-200是 "中度污染"， 201-250是 "重度污染"。 AQI超過300的時候， 政府會叫民眾留在家裡不要到戶外運動。
In Tainan there are monitoring stations in downtown Tainan, Annan, Shanhua, Madou, Xuejia and Xinying. In Kaohsiung there are monitoring stations in Linyuan, Daliao, Xiaogang, Qianjhen, Fuxing, Fengshan, Qianjin, Zuoying, Renwu, Nandze, Qiaotou, Hunei and Meinong. In Pingtung there are monitoring stations in Hengchun, Fangliao, Xiaoliuqiu, Chaozhou and Pingtung City. 台南在台南市區 、 安南 、 善化 、 麻豆 、 學甲跟新營 有環境監測站。 高雄的環境監測站在林園 、 大寮 、 小港 、 前鎮 、 復興 、 鳳山 、前金 、 左營 、 仁武 、楠梓 、橋頭 、 湖內跟美濃 。 屏東的環境監測站在恆春 、 枋寮 、 小琉球、潮州跟屏東市 。
I'm using the readings for February 11, 2022 in this entry. The prevailing wind was from the east, and there was a convection cell off the west coast. The worst air in Taiwan was in central Kaohsiung, and the best was in Taitung. 下列是二月十一日的空氣品質指數 ， 風向從東到西 ， 本島西部也有個對流 ， 這一天本島高雄市區的空氣品質最差， 台東的空氣品質最好 。
The worst AQI reading in the world was in Dhaka, Bangladesh at 294.世界上空氣品質最差的地方就是孟加拉國的達卡市 ， 那邊的空氣品質是294AQI。

Most of Tainan's industry is located in and around downtown Tainan, but there are a lot of livestock and food processing operations northeast of there. Tainan has a smaller population, less industry and less traffic than Kaohsiung, so of course their air is better. 台南大部分的工廠在市區或市區附近 ， 可是它的東北部有很多畜牧業跟食品加工業 。 台南的人口 、工業 、 交通流量都比高雄少 ，所以空氣品質相對地比較好 。

It's hard to tell whether Kaohsiung's air quality has more to do with traffic or with factory emissions. Both are obvious problems in a city this size, and the distribution of industrial areas throughout the city make it harder to trace air pollution to its source. One thing's for sure, the air around Meinong, located near the mountains, is much cleaner. 高雄的空氣品質很難說是受到交通的影響比較大或是工廠排放的廢氣。 這兩個問題在那麼大的城市裡 顯而易見 ，只是高雄到處都有工廠 ， 有時候真難知道空氣污染的源頭在哪裡。 但有一件事是確定的， 靠近山區的美濃空氣品質比較良好 。

Pingtung's air quality was discussed a year ago in the the Air Quality in Pingtung entry. Pingtung's air is on average better than Kaohsiung and Tainan's. It has a smaller population, less traffic overall, and fewer factories. Pingtung City and Xiaoliuqiu, which are both closer to Kaohsiung, usually have the worst air, but as you move south toward Hengchun the air gets considerably better. 屏東的空氣品質在一年前的屏東的空氣品質討論過。 屏東的空氣品質平均比高雄跟台南好 ， 人口 、 車輛 、 工廠都比較少 。 屏東市跟小琉球都比較靠近高雄 ， 所以空氣品質常常比較差 。 往恆春的方向走， 空氣品質也越來越好 。
As said before, assigning a single number (or color) to Pingtung's air quality is very misleading. The areas south of Fangliao are shielded by the mountains, and the wind rarely blows southeast toward that part of the county. Everything from Fangliao to Pingtung City lies on a vast agricultural plain, and this plain stretches all the way north to the air monitoring stations in Tainan. 給全屏東縣空氣品質一個指數 (或是一個顏色) 是不對的資訊 。 枋寮到最南端的部分被山脈擋住 ， 風向也很少從西北吹向東南。 枋寮到屏東市中間主要都是農業平原 ， 這個平原也往北包含了台南的監測站 。
We'll see if the government's "green energy plan" brings about a change in local air quality. I'm a bit skeptical given the seeming lack of oversight and the number of private companies involved, but it's encouraging that the government realizes this is a problem and is taking steps to fix it. 我們一起看政府的 "綠色能源計畫" 能否改善當地的空氣品質。 我覺得政府的監督不夠 ，也有太多私人公司利益混在政策內 。 但往好的一面看， 政府也看到了這個問題並採取行動改善。
After all, which is more dangerous in the long term - viruses, or the air many of us are breathing? 話說回來 , 疫情或是我們吸的空氣，長遠來看哪一個比較危險 ?
