[:ja]NASAの地球観測衛星Suomi NPPが撮影したタイのスモッグです。これは、焼き畑農業からの煙と大気汚染の両方により健康への懸念が出る濃度で発生しています。
農業からの煙は一時的なもので、タイではむしろ大気汚染の方が深刻です。タイでは、経済発展に伴い、自動車の排気ガスや工場などからの粉塵に含まれるPM2.5が増加しています。現地報道によると、バンコク都内10カ所の観察地点における平均のPM2.5濃度は、1平方メートル当たり65マイクログラムと、タイ政府が安全と見なす50マイクログラムを大きく上回っています。また、バンコク周辺部では、137マイクログラムを計測した地域もあり、都心に限らず周辺部でも高い水準が続いています。タイ政府は、大気汚染が深刻化している現状を受け、1月31日からの2日間、バンコク市内および周辺部の幼稚園、学校、各種専門学校の臨時休校を決定しています。また、プラユット首相は「朝、昼、夜、その他粉じんの量が多い時間帯において、一時的に操業が停止できるよう、企業は準備しておくべきだ」と述べ、今後、タイ政府が一段と強い措置に踏み込む場合は、日系企業の操業にも大きな影響が出る可能性もあります。

[Earthview Wonders] No.745: Air Pollution in Thailand🇹🇭
NASA’s Suomi NPP satellite captured the severe air pollution over Thailand.
For more than a month, northern Thailand has been experiencing unhealthy, elevated levels of smoke and air pollution. The thick haze is a result of wildfires and prescribed burning by farmers clearing their land for the planting season. Meteorologists expect the unhealthy air quality to last into May. This is a combination of the haze caused by farming wildfires and the air pollution, but the latter is more significant. On the back of strong economic growth, Thailand has been choking on air pollution. Bangkok’s air quality has fallen to harmful levels with the quantity of unsafe dust particles, known as PM2.5, exceeding what is considered safe in 41 areas around the capital, according to the country’s Department of Pollution Control. On January 31, 2019, Thailand’s Ministry of Education has ordered all schools in Bangkok and some surrounding provinces to close for the remainder of the week amid concerns over dangerous levels of air pollution.
The local scenery on the ground is as follows.
