The Air Pollution Control Act is the main legislation concerning air pollution in Japan. Niigata Minamata was caused by methylmercury poisoning in the Agano River basin. Today, Chisso makes compensation payments to all certified (recognized) patients of Minamata disease. Specific diseases such as bronchial asthma, chronic bronchitis, pulmonary emphysema, and their complications. [6] The methylmercury inside the contaminated fish attacked the afflicted patient's central nervous system, which caused a variety of symptoms. Since the end of World War II, Japan has strongly upgraded the industrial infrastructure and developed heavy-industrialization since about the 25th year of the Showa period. The four big pollution diseases of Japan (四大公害病, yondai kōgai-byō) were a group of man-made diseases all caused by environmental pollution due to improper handling of industrial wastes by Japanese corporations. The cause of this contamination in Minamata bay was then traced back to Chisso Corporation’s dumping of methylmercury into Minamata Bay. In specific areas where the prevalence of that disease has increased. The first symptoms were spine and leg pain. Current Status on Tackling Air Pollution in Japan Author: Mr. Tatsuya Yanase Subject: The 2nd Roundtable on Transboundary Air Pollution in Northeast Asia Keywords: Air, Environment, Environmental Damage, Environmental Impact Assessment, Transboundary Air Pollution, Transboundary Environmental Impact, Transboundary Pollution Created Date Unfortunately, this refinery was not equipped with machines that could lower the sulfur dioxide emissions before releasing them into the air. Mitsui Mining was also obliged to pay recovery costs for the land. pollution over east China A number of prefectures are issuing an increased number of photochemical smog warning, in one case causing the canceling of athletic events at 85 primary schools. Japan began tackling its pollution problem back in the 1970s when particulate matter levels in the air (PM2.5) reached dangerously high levels around all the major cities. The source of cadmium was discovered to be from Mitsui Mining and Smelting Company. A large amount of pollutants had been emitted because of the massive increase in industrial ma… Rediscovery of the Minamata disease in Niigata", "AIR POLLUTION IN YOKKAICHI AREA WITH SPECIAL REGARDS TO THE PROBLEM OF "YOKKAICHI -ASTHMA", "AIR POLLUTION IN YOKKAICHI AREA WITH SPECIAL REGARDS TO THE PROBLEM OF "YOKKAICHI -ASTHMA, "Mortality and life expectancy of Yokkaichi Asthma patients, Japan: Late effects of air pollution in 1960–70s", https://en.wikipedia.org/w/index.php?title=Four_Big_Pollution_Diseases_of_Japan&oldid=985189469, Articles containing Japanese-language text, Wikipedia articles needing clarification from April 2014, Creative Commons Attribution-ShareAlike License, decrease in communication skills (slurred speech). [1] The first occurred in 1912, and the other three occurred in the 1950s and 1960s. Most patients exhibited combinations of symptoms and did not show all symptoms. "The Wound Left by the Sharp Knife of Industrial Pollution", "What is ouch ouch or Itai itai disease? Japanese Environmental Pollution Experience The history of pollution in Japan. Once connected, air pollution levels are reported instantaneously and in real-time on our maps The cadmium poisoned the river, thus poisoning locals' source of water. As such, much of that air pollution gets blown east from northeastern China over the Korean Peninsula and Japan, and sometimes you get really bad air in Japan, especially when the dust storms that start in the Gobi Desert get blown eastwards and turn the skies of Japan into a tan-color haze like the old Stage II alert smog that used to plague Los Angeles up until the early 1990’s. In fact, the worst region in Japa… Along the Agano River basin there were several plants that used mercury in production, agricultural chemicals were widely used in the area, and the last possible cause of the outbreak was said to be the cause of an earthquake that took place a year before the disease was discovered in Niigata. The degree of this outbreak was minimal[clarification needed] compared to that of the first Minamata disease that took place in Kumamoto prefecture. [3] Mitsui Mining began to discharge cadmium into the Jinzū River in 1910. Japan Air Quality Index (AQI). This increase in respiratory problems was then specified as Yokkaichi asthma. acidic precipitation). The cause of itai-itai disease was determined to be cadmium poisoning in the drinking water from the Jinzū River basin. Around the 20th year of the Meiji Period, the mineral pollution case of the Ashio Copper Mine came to be known as the first pollution case that occurred in Japan. The methylmercury was then dumped into Minamata Bay as chemical waste. In the middle of this city was the largest heavy oil-fired power station and refinery in Japan during this time period. - Tokyo's History with Air Pollution The history of institutional steps by the government to address environmental issues this century begins with anti-pollution measures. Furthermore, the majority of the western side of Japan receives large amounts of wet deposition acidic compounds (i.e. Around the 20th year of the Meiji Period, the mineral pollution case of the Ashio Copper Mine came to be known as the first pollution case that occurred in Japan. Three years of residence within the specified area. Residents won this lawsuit and began to conduct negotiations. Due to lawsuits, publicity, and other actions against the corporations responsible for the pollution, as well as the creation of the Environmental Agency in 1971, increased public awareness, and changes in industrial practices, the incidence of these kinds of diseases declined after the 1970s. The air pollution is resulted mostly from the combusion of fossil fuels, e. g. factories, thermal power plants and motor vehicles. Then in 1997, after fourteen years and $359 million,[7] the Governor of Kumamoto Prefecture deemed Minamata Bay safe.[8]. What's the air pollution in Japan like during: During the winter, air pollution in Japan is particularly bad since the polluted air comes not only from industrial and vehicle emissions within Japan, but also from polluted air masses that are derived from China. These laws help keep the disaster of Yokkaichi Asthma from happening once again within Japan's borders. Regarding protection of the ozone layer, the Ozone Layer Protection Act regulates the manufacture and import of specified substances that deplete the ozone layer. Based on the Act, the government has established the Basic Environment Plan, and has also established environmental quality standards with regard to air pollution, water pollution, soil contamination, and noise.The prefectural governors may also formulate environmental pollution control programs for specific areas if environmental pollution in the area is currently serious or could be worse… Air Pollution in Japan clean energy production Air pollution includes particles of soot, organic hazardous material, heavy metals, acid aerosols and dust. Acetaldehyde was also used to produce acetic acid by oxidizing acetaldehyde and vinyl chloride, Japan began tackling its pollution problem back in the 1970s when particulate matter levels in the air (PM2.5) reached dangerously high levels around all the major cities. Mitsui Mining formally admitted that itai-itai disease was caused by their discharge of cadmium into the Jinzū River. [5] After an extensive investigation, the Minamata disease was identified as a heavy metal poisoning, specifically methylmercury poisoning, transmitted by the ingestion of contaminated fish from Minamata Bay. ", "10 Things to know about Minamata Disease", "Minamata Disease The History and Measures", "Japan Call Mercury-Poisoned Bay Safe Now", "VII. The problems can be traced back to the rapid industrialization of Japan that began during the Meiji period in the 19 th century. Investigation of the cause of the disease was given to the Niigata University medical department. which is polymerized to make PVC; however, the use of ferric sulfide had a downside: methylmercury (or organic mercury) was a by-product in the making of these chemicals due to its use. Read the air pollution in Japan, get real-time, historical and forecast PM2.5 and weather data with AirVisual. 1. Very easy to set up, they only require a WIFI access point and a USB power supply. The increases are believed to be linked to pollution from China. Any person who drank that water or ate food that was grown with the contaminated water, such as rice, would be likely to show signs of itai-itai disease. This meant that they had to ensure the poisoned land was returned to a safe and cultivable state. These cases also set precedents for private tort law and civil law in issues of compensation for technology-related mass damage which continue to have repercussions in legal cases in Japan today.[2]. In the early 1960s, respiratory diseases began to emerge in the general population of Yokkaichi and even in some neighboring districts. The first report of Minamata disease originated in Minamata in Kumamoto Prefecture in the year 1956. The Basic Environment Law and the Basic Environment Plan The Basic Environment Plan is based on the basic plan for environmental conservation Article 15, The Basic Environment Law, and was decided by the cabinet while consulting the Central Environment Council. Much like Chisso corporation, Showa Denko declined all charges that they were at fault for the Niigata Minamata outbreak. However, as the disease progresses symptoms include:[4]. Air Pollution in Japan from China . [10] Construction of the first oil refinery in this area first began in 1955[11] and after construction many respiratory diseases emerged within the city and among neighboring districts. The smaller particles are sometimes more dangerous because they are more easily inhaled and go deeper into the lungs. In the year that Niigata Minamata was discovered, 26 people were designated disease patients, and five died as a result of the methylmercury poisoning. The four big pollution diseases of Japan (四大公害病, yondai kōgai-byō) were a group of man-made diseases all caused by environmental pollution due to improper handling of industrial wastes by Japanese corporations. Chisso Corporation produced acetaldehyde using water, acetylene, mercury(II) sulfate as a catalyst and manganese dioxide or since August 1951, ferric sulfide as a co-catalyst. Itai-itai disease first occurred in 1912 within Toyama Prefecture. However, this second outbreak of Minamata disease was discovered early on. Read the air pollution in Japan, get real-time, historical and forecast PM2.5 and weather data with AirVisual. As the name implies, Niigata Minamata disease is similar to Minamata disease; they both share the similar symptoms: In the spring of 1966, the research team determined the most likely cause to the dumping of methylmercury from Showa Denko Corporation factory. To offer support for many of the victims of this disease, a public release system for air pollution was established in 1965. The history of pollution in Japan goes back to the beginning of the Meiji Period. This form of asthma was prevalent within Yokkaichi — 5–10% of inhabitants aged 40 in Yokkaichi were reported to suffer from chronic bronchitis, whereas less than 3% suffered from the same disease in non-polluted areas.[12]. Most victims of itai-itai disease were confined to bed because walking caused severe pain. In 1977, the Japanese government took on the task of cleaning Minamata Bay by vacuuming out 1.5 million cubic metres of methylmercury-contaminated sludge from the bottom of the bay and using them to reclaim over 50 hectares of the bay along with non-contaminated soil on top. The GAIA air quality monitoring stations are using high-tech laser particle sensors to measure in real-time PM2.5 pollution, which is one of the most harmful air pollutants. The problems can be traced back to the rapid industrialization of Japan that began during the Meiji period in the 19th century. It declare… Post-war Japan experienced a rapid economic recovery, and entered an age of high economic growth.
