The following list of countries by air pollution sorts the countries of the world according to their average measured concentration of particulate matter in micrograms per cubic meter (μg/m 3). The World Health Organization's recommended limit is 10 micrograms per cubic meter, although there are also various national guideline values, which ...
The most commonly used air quality index in the UK is the Daily Air Quality Index recommended by the Committee on the Medical Effects of Air Pollutants (COMEAP). [39] This index has ten points, which are further grouped into four bands: low, moderate, high and very high. Each of the bands comes with advice for at-risk groups and the general ...

An AQI value of 50 or below represents good air quality, per the EPA, while an AQI value over 300 represents hazardous air quality. An AQI value of 100 is considered the threshold for safe air ...
The highest massif is Mount Fukushima (2,470 m). The Japanese Antarctic Research Expedition (JARE) found the Yamato 000593 Martian meteorite in 2000 on the Yamato Glacier, at the Queen Fabiola Mountains. [2] With a mass of 13.7 kg (30.2 lb), Yamato 000593 is the second largest meteorite from Mars found on Earth. [2] [3] [4]
Scale reading for fine particulate matter crosses the 1,000 mark in Delhi for the first time this year
Eastern Antarctica is to the right of the Transantarctic Mountains and Western Antarctica is to the left. Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle (one of the five major circles of latitude that mark maps of the world), Antarctica is surrounded by the Southern Ocean .
