Worldwide, PM 10 concentrations of 70 μg/m 3 and PM 2.5 concentrations of 35 μg/m 3 have been shown to increase long-term mortality by 15%. [29] More so, approximately 4.2 million of all premature deaths observed in 2016 occurred due to airborne particulate pollution, 91% of which occurred in countries with low to middle socioeconomic status.
This list contains the top 500 cities by PM2.5 annual mean concentration measurement as documented by the World Health Organization covering the period from 2008 to 2017. The 2018 version of the WHO database contains results of ambient (outdoor) air pollution monitoring from almost 2700 towns and cities in 91 countries.
Below is a list of 526 cities sorted by their annual mean concentration of PM2.5 (μg/m 3) in 2022. [1] [2] By default the least polluted cities which have fewest particulates in the air come first.
Iran is among the most vulnerable countries to climate change in the Middle East and North Africa (MENA). Iran contributes to about 1.8% of global greenhouse gas emissions (GHG), and is ranked 8th in greenhouse gas emissions (GHG) world wide and is ranked first in the MENA region due to its reliance on oil and natural gas. Climate change has ...
Similarly, fine particulate matter (PM 2.5) tends to penetrate into the gas exchange regions of the lung (alveoli), and very small particles (ultrafine particulate matter PM 0.1) may pass through the lungs to affect other organs. Penetration of particles is not wholly dependent on their size; shape and chemical composition also play a part.
Lebanon (/ ˈ l ɛ b ə n ɒ n,-n ə n / ⓘ LEB-ə-non, -nən; Arabic: لُبْنَان, romanized: Lubnān, local pronunciation: [lɪbˈneːn]), officially the Republic of Lebanon, [c] is a country in the Levant region of West Asia, bordered by Syria to the north and east, Israel to the south, and the Mediterranean Sea to the west; Cyprus lies a short distance from the country's coas
The Middle East and North Africa (MENA), also referred to as West Asia and North Africa (WANA) [1] or South West Asia and North Africa (SWANA), [2][3] is a geographic region which comprises the Middle East (also called West Asia) and North Africa together. However, it is widely considered to be a more defined and apolitical alternative to the ...
The mandate system was established by Article 22 of the Covenant of the League of Nations, drafted by the victors of World War I. The article referred to territories which after the war were no longer ruled by their previous sovereign, but their peoples were not considered "able to stand by themselves under the strenuous conditions of the modern world".
