2020 Chernobyl Exclusion Zone Wildfires
The 2020 Chernobyl Exclusion Zone wildfires were a series of wildfires that began burning inside Ukraine's Chernobyl Exclusion Zone in April 2020. The fires were largely extinguished within two weeks. At least one suspect was arrested for alleged arson. Timeline On April 6, it was reported that radiation levels inside the zone were "16 times above normal" as a result of the fires. As the fire spread, a small village near the mostly abandoned town of Poliske was evacuated on April 10. By April 13, the wildfires had spread to just over away from the Chernobyl Nuclear Power Plant and had reached the outskirts of the abandoned city of Pripyat. More than 300 firefighters worked to stop the fires from reaching the plant. By 11 April, the firefighters had reached close to 400, with many helicopters and 100 fire engines dispersed to the Chernobyl exclusion zone. The State Emergency Service of Ukraine said it was still fighting the fires, but that the situation was under control, while G ...

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire( in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurrence of wildfires throughout the history of terrestrial life invites conjecture tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haze
Haze is traditionally an atmospheric phenomenon in which dust, smoke, and other dry particulates suspended in air obscure visibility and the clarity of the sky. The World Meteorological Organization manual of codes includes a classification of particulates causing horizontal obscuration into categories of fog, ice fog, steam fog, mist, haze, smoke, volcanic ash, dust, sand, and snow. Sources for particles that cause haze include farming (ploughing in dry weather), traffic, industry, volcanic activity and wildfires. Seen from afar (e.g. an approaching airplane) and depending on the direction of view with respect to the Sun, haze may appear brownish or bluish, while mist tends to be bluish grey instead. Whereas haze often is thought of as a phenomenon occurring in dry air, mist formation is a phenomenon in saturated, humid air. However, haze particles may act as condensation nuclei that leads to the subsequent vapor condensation and formation of mist droplets; such forms of ...

Arson In Europe
Arson is the crime of willfully and deliberately setting fire to or charring property. Although the act of arson typically involves buildings, the term can also refer to the intentional burning of other things, such as motor vehicles, watercraft, or forests. The crime is typically classified as a felony, with instances involving a greater degree of risk to human life or property carrying a stricter penalty. Arson which results in death can be further prosecuted as manslaughter or murder. A common motive for arson is to commit insurance fraud. In such cases, a person destroys their own property by burning it and then lies about the cause in order to collect against their insurance policy. A person who commits arson is referred to as an arsonist, or a serial arsonist if arson has been committed several times. Arsonists normally use an accelerant (such as gasoline or kerosene) to ignite, propel and directionalize fires, and the detection and identification of ignitable ...

Fires In Ukraine
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The '' flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and property, atmospheric pollution, and water contamination. If ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Disasters In Ukraine
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term '' environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its con ...

April 2020 Events In Ukraine
April is the fourth month of the year in the Gregorian and Julian calendars. It is the first of four months to have a length of 30 days, and the second of five months to have a length of less than 31 days. April is commonly associated with the season of autumn in parts of the Southern Hemisphere, and spring in parts of the Northern Hemisphere, where it is the seasonal equivalent to October in the Southern Hemisphere and vice versa. History The Romans gave this month the Latin name '' Aprilis''"April" in ''Chambers's Encyclopædia''. London: George Newnes, 1961, Vol. 1, p. 497. but the derivation of this name is uncertain. The traditional etymology is from the verb ''aperire'', "to open", in allusion to its being the season when trees and flowers begin to "open", which is supported by comparison with the modern Greek use of άνοιξη (''ánixi'') (opening) for spring. Since some of the Roman months were named in honor of divinities, and as April was sac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Pollution In China
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. The affected area accounts of one-tenth of China's cultiva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
