Air Pollution In South Korea
Air pollution in South Korea is an increasing threat to people and the environment. The air pollution comes from many sources, both domestic and international. Many forms of pollution have increased in South Korea since its rapid industrialization, especially in Seoul and other cities. According to the U.S. National Aeronautics and Space Administration (NASA), Seoul is one of the world's cities with the worst air pollution. From 2009 and 2013, the city's mean PM10 were higher than in many of the largest metropolitan cities in the world such as: Los Angeles, Tokyo, Paris, and London. This has resulted in health and environmental problems. Koreans buy masks and air purifiers to breathe cleaner air, and are working to reduce the country's emissions. Overview South Korea has the worst air quality of the 35 richest countries in the world that are part of the OECD. Without the pollution coming from China, South Korea would be below the OECD average. According to the 2019 World Air Qual ...

Pollution In South-Korea
Pollution in Korea has become diversified and serious due to rapid industrialization and urbanization since the 1960s. The causes of environmental pollution, both in South and North Korea, can be found in population growth, urban concentration, and industrial structure, similar to the rest of the world. Pollution in South Korea Air pollution Air pollution refers to the fact that the constituents of the atmosphere change due to the excessive presence of pollutants emitted artificially and naturally, and their quality deteriorates, which adversely affects the life activities of humans and animals, and plants. Air pollutants can be broadly divided into gaseous substances and particulate matter. Gaseous substances are generated by the combustion, synthesis, and decomposition of substances. Particulate matter occurs when the material is crushed, sorted, transported, or otherwise mechanically treated or burned, synthesized, or decomposed. When air pollutants are classified accord ...

Construction Equipment
Heavy equipment or heavy machinery refers to heavy-duty vehicles specially designed to execute construction tasks, most frequently involving earthwork operations or other large construction tasks. ''Heavy equipment'' usually comprises five equipment systems: the implement, traction, structure, power train, and control/information. Heavy equipment has been used since at least the 1st century BC when the ancient Roman engineer Vitruvius described a crane in ''De architectura'' when it was powered via human or animal labor. Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature. Some equipment uses hydraulic drives as a primary source of motion. The term "plant" is used to refer to any mobile type of heavy machinery. History The use of heavy equipment has ...

Fossil Fuel
A fossil fuel is a hydrocarbon-containing material formed naturally in the Earth's crust from the remains of dead plants and animals that is extracted and burned as a fuel. The main fossil fuels are coal, oil, and natural gas. Fossil fuels may be burned to provide heat for use directly (such as for cooking or heating), to power engines (such as internal combustion engines in motor vehicles), or to generate electricity. Some fossil fuels are refined into derivatives such as kerosene, gasoline and propane before burning. The origin of fossil fuels is the anaerobic decomposition of buried dead organisms, containing organic molecules created by photosynthesis. The conversion from these materials to high-carbon fossil fuels typically require a geological process of millions of years. In 2019, 84% of primary energy consumption in the world and 64% of its electricity was from fossil fuels. The large-scale burning of fossil fuels causes serious environmental damage. Over 80% of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal In China
China is the largest producer and consumer of coal in the world. It is also the largest user of coal-generated electricity, with over a thousand coal-fired power stations. The share of coal in the energy mix declined during the 2010s, falling from 80% in 2010 to 58% in 2019. China emits over 10% of global greenhouse gas. China's large demand was in part responsible for the delay in peak global coal production, coal production reached a record high in December 2021 and coal consumption in China is forecast to reach a record high in 2021. Overall electricity consumption continued to rise in the 2010s, and new coal-fired power plants were constructed to help meet demand. But to curtail the pace of coal-fired power station construction, the National Energy Administration in 2017 canceled coal-fired power plant permits that would have amounted to 120 GW of future capacity. However, local authorities seeking to create jobs resisted the efforts of central authorities to cut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Pollutants
Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane, carbon dioxide and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and food crops, and may damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). Air pollution can be caused by both human activities and natural phenomena. Air pollution is a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, ...

Smog
Smog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a portmanteau of the words ''smoke'' and '' fog'' to refer to smoky fog due to its opacity, and odor. The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid-20th century. This kind of visible air pollution is composed of nitrogen oxides, sulfur oxide, ozone, smoke and other particulates. Man-made smog is derived from coal combustion emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions. Smog is often categorized as being either summer smog or winter smog. Summer smog is primarily associated with the photochemical formation of ozone. During the summer season when the temperatures are warmer and there is more sunlight present, photochemical smog is the dominant type of smog formation. Du ...

Coal-fired Powerplants
A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. Worldwide, there are about 8,500 coal-fired power stations totaling over 2,000 gigawatts capacity. They generate about a third of the world's electricity, but cause many illnesses and early deaths, mainly from air pollution. A coal-fired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators. Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy. Coal-fired power stations emit over 10 Gt of carbon dioxide each year, about one fifth of world greenhouse gas emissions, so are the single largest cause of climate change. More than half of all the coal-fired electricity in the world is generated in C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
