2013 Harbin Smog
A dense wave of smog began in Northeast China, especially in major cities including Harbin, Changchun and Shenyang, as well as the surrounding Heilongjiang, Jilin, and Liaoning provinces on 20 October 2013. Unseasonably warm temperatures with very little wind across northeastern China coincided with the initiation of Northeast China's coal-powered municipal heating system. Record densities of fine particulates were measured in the city. In Harbin, the levels of PM2.5 particulate matter rose to 1,000 micrograms per cubic metre, worse than Beijing's historic highs. Visibility dropped to and authorities grounded flights and closed more than 2,000 schools. In Changchun, air pollution recorded at an all-time high and the levels of PM2.5 particulate matter rose to 845 micrograms per cubic metre on 22 October 2013. The smog eased on 25 October 2013 and had completely dissipated by the 28th due to a cold front that had moved in from Russia. Background Officials blamed the dens ...

Particulate
Particulates – also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM) or suspended particulate matter (SPM) – are microscopic particles of solid or liquid matter suspended in the air. The term ''aerosol'' commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be natural or anthropogenic. They have impacts on climate and precipitation that adversely affect human health, in ways additional to direct inhalation. Types of atmospheric particles include suspended particulate matter; thoracic and respirable particles; inhalable coarse particles, designated PM, which are coarse particles with a diameter of 10 micrometers (μm) or less; fine particles, designated PM, with a diameter of 2.5 μm or less; ultrafine particles, with a diameter of 100 nm or less; and soot. The IARC and WHO designate airborne particulates as a Group 1 carcinogen. Particulates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Respiratory
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs; in mammals and reptiles these are called alveoli, and in birds they are known as atria. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and terti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airpocalypse
Pollution in China is one aspect of the broader topic of environmental issues in China. Various forms of pollution have increased as China has industrialised, which has caused widespread environmental health problems.Jared Diamond, '' Collapse: How Societies Choose to Fail or Succeed'', Penguin Books, 2005 and 2011 (). See chapter 12 entitled "China, Lurching Giant" (pages 258–377). Pollution statistics The immense growth of the People's Republic of China since the 1980s has resulted in increased soil pollution. The State Environmental Protection Administration believes it to be a threat to the environment, food safety and sustainable agriculture. 38,610 square miles (100,000 km2) of China's cultivated land have been polluted, with contaminated water being used to irrigate further 31.5 million miles (21,670 km2.), and another 2 million miles (1,300 km2) have been covered or destroyed by solid waste.
