The city with the most polluted air in the world has been revealed: It was affected by toxic fumes

Toxic smoke from ongoing forest fires in Indonesia has caused respiratory diseases in tens of thousands of people since August. Air quality in Indonesia, as well as Malaysia and Singapore, has deteriorated due to dense and toxic smoke.

According to data from Switzerland-based air quality monitoring company IQAir, Singapore, one of the richest cities in the world, became "the most polluted city in the world" by being affected by the dense and toxic smoke layer caused by fires in neighboring Indonesia. Air quality in Singapore city today measured 216, classifying it as "very unhealthy", according to IQAir.

Singapore's National Environment Agency announced that the hazy weather was caused by the recent drought in the region and fires in some parts of Indonesia. Authorities regularly issued warnings, urging the public to drink plenty of water and reduce outdoor activities. While schools were told to reduce long-term outdoor activities, some schools were provided with air purifiers for use in classrooms.

SCHOOLS WERE CLOSED IN MANY STATES

Kuala Lumpur, Malaysia, which was affected by the fires in Indonesia, ranked second in the list of "world's most polluted cities".

Air quality index values, which show the level of air pollution, are classified as "good" in the range of 0-50, "medium" in the range of 51-100, "sensitive" in the range of 101-150, "unhealthy" in the range of 151-200, "bad" in the range of 201-300 and "dangerous" in the range of 301-500.

Air quality in Malaysia's Johor state also reached "very unhealthy" levels. All schools in the state were closed for 2 days. Authorities in many other states of Malaysia, including Malacca, Negeri Sembilan and the state of Selangor, where the capital Kuala Lumpur is located, have also decided to suspend education as air quality continues to deteriorate. Authorities also ordered other schools to close if air pollution readings exceed 180.
