Yokkaichi Asthma
refers to cases of chronic obstructive pulmonary disease, chronic bronchitis, pulmonary emphysema, and bronchial asthma in humans and various environmental changes usually attributed to sulfur dioxide (SO2) emissions which appeared as smog over the city of Yokkaichi in Mie Prefecture, Japan between 1960 and 1972, though other SOx compounds have been proposed. The generally accepted source of the sulfur oxide pollution was the Yokkaichi Kombinato petrochemical processing facilities and refineries built in Yokkaichi between 1959 and 1972 which did not properly desulfurize the high sulfur content in its crude oil. Yokkaichi asthma is considered one of the Four Big Pollution Diseases of Japan and was the subject of Japan's first court case related to pollution. Industry background In 1899, wealthy Yokkaichi landowner Inaba San'emon transformed Yokkaichi's wetlands into a port for textile exports. Ishihara Industries built an oil refinery in Yokkaichi's remaining marshes in 1937. In 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chronic Obstructive Pulmonary Disease
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by long-term respiratory symptoms and airflow limitation. The main symptoms include shortness of breath and a cough, which may or may not produce mucus. COPD progressively worsens, with everyday activities such as walking or dressing becoming difficult. While COPD is incurable, it is preventable and treatable. The two most common conditions of COPD are emphysema and chronic bronchitis and they have been the two classic COPD phenotypes. Emphysema is defined as enlarged airspaces ( alveoli) whose walls have broken down resulting in permanent damage to the lung tissue. Chronic bronchitis is defined as a productive cough that is present for at least three months each year for two years. Both of these conditions can exist without airflow limitation when they are not classed as COPD. Emphysema is just one of the structural abnormalities that can limit airflow and can exist without ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flue-gas Desulfurization
Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide () from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration. Methods Since stringent environmental regulations limiting emissions have been enacted in many countries, is being removed from flue gases by a variety of methods. Common methods used: * Wet scrubbing using a slurry of alkaline sorbent, usually limestone or lime, or seawater to scrub gases; * Spray-dry scrubbing using similar sorbent slurries; *Wet sulfuric acid process recovering sulfur in the form of commercial quality sulfuric acid; * SNOX Flue gas desulfurization removes sulfur dioxide, nitrogen oxides and particulates from flue gases; *Dry sorbent injection systems that introduce powdered hydrated lime (or other sorbent material) into exhaust ducts to eliminate and from process emissions. For a typical coal-fired power station, flue-ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfur Dioxide
Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula . It is a toxic gas responsible for the odor of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of sulfur- bearing fossil fuels. Structure and bonding SO2 is a bent molecule with ''C''2v symmetry point group. A valence bond theory approach considering just ''s'' and ''p'' orbitals would describe the bonding in terms of resonance between two resonance structures. The sulfur–oxygen bond has a bond order of 1.5. There is support for this simple approach that does not invoke ''d'' orbital participation. In terms of electron-counting formalism, the sulfur atom has an oxidation state of +4 and a formal charge of +1. Occurrence Sulfur dioxide is found on Earth and exists in very small concentrations and in the atmosphere at about 1 ppm. On other planets, ...

Tsukiji
Tsukiji (築地) is a district of Chūō, Tokyo, Japan. Literally meaning "reclaimed land", it lies near the Sumida River on land reclaimed from Tokyo Bay in the 18th century during the Edo period. The eponymous Tsukiji fish market opened in 1935 and closed in 2018 when its operations were moved to the new Toyosu Market. There are also districts named ''Tsukiji'' in Kobe and Amagasaki, cities in Hyōgo Prefecture, although neither is as well known as the district in Tokyo. History Tsukiji is built on reclaimed land out of what were once lowland marshes along the Sumida River delta. Throughout the Tokugawa period, earth from the shogunate's extensive moat and canal excavations was systematically used to fill in the marshes along the river, creating new commercial districts and waterfront housing. The land was then named Tsukiji (築地), meaning "constructed land" or "reclaimed land". The Great Fire of Meireki of 1657 destroyed over two-thirds of Edo's buildings, including Hong ...

Suzuka River
The is a major river that flows through northern Mie Prefecture on the island of Honshū, Japan. It is officially classified as a Class 1 river by the Japanese government, one of four Class 1 rivers that flow solely through Mie. The river's source is on Mount Nasugahara, which stands on the border of Mie and Shiga Prefectures. From the mountain, it then flows eastwards, eventually flowing into Ise Bay. A section of the Tōkaidō, a major travel route in the Edo era, ran along the north side of the river for most of its course. The modern versions of this portion of the old Tokaido, the Kansai Main Line and Route 1, likewise run parallel with the river.

Reclaimed Land
Land reclamation, usually known as reclamation, and also known as land fill (not to be confused with a waste landfill), is the process of creating new Terrestrial ecoregion, land from oceans, list of seas, seas, Stream bed, riverbeds or lake beds. The land reclaimed is known as reclamation ground or land fill. In some jurisdictions, including parts of the United States, the term "reclamation" can refer to returning disturbed lands to an improved state. In Alberta, Canada, for example, reclamation is defined by the provincial government as "The process of reconverting disturbed land to its former or other productive uses." In Oceania, it is frequently referred to as land rehabilitation. History One of the earliest large-scale projects was the Beemster, Beemster Polder in the Netherlands, realized in 1612 adding of land. In Hong Kong the Praya Reclamation Scheme added of land in 1890 during the second phase of construction. It was one of the most ambitious projects ever tak ...
