The environmental movement, also including conservation and green politics, is a diverse scientific, social, and political movement for addressing environmental issues. Environmentalists advocate the sustainable management of resources and stewardship of the environment through changes in public policy and individual behavior. In its recognition of humanity as a participant in ecosystems, the movement is centered on ecology, health, and human rights.
A toxic heavy metal is any relatively dense metal or metalloid that is noted for its potential toxicity, especially in environmental contexts. The term has particular application to cadmium, mercury, lead and arsenic, all of which appear in the World Health Organization's list of 10 chemicals of major public concern. Other examples include manganese, chromium, cobalt, nickel, copper, zinc, selenium, silver, antimony and thallium.
Metal fume fever, also known as brass founders' ague, brass shakes, zinc shakes, galvie flu, metal dust fever, Welding Shivers, or Monday morning fever, is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al2O3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are heated. Other common sources are fuming silver, gold, platinum, chromium (from stainless steel), nickel, arsenic, manganese, beryllium, cadmium, cobalt, lead, selenium, and zinc.
Environmental pollution in Japan has accompanied industrialization since the Meiji period. One of the earliest cases was the copper poisoning caused by drainage from the Ashio Copper Mine in Tochigi Prefecture, beginning as early as 1878. Repeated floods occurred in the Watarase River basin, and 1,600 hectares of farmland and towns and villages in Tochigi and Gunma prefectures were damaged by the floodwater, which contained excessive inorganic copper compounds from the Ashio mine. The local breeders led by Shōzō Tanaka, a member of the Lower House from Tochigi appealed to the prefecture and the government to call a halt to the mining operations. Although the mining company paid compensatory money and the government engaged in the embankment works of the Watarase river, no fundamental solution of the problem was achieved.
The environment of South Korea is the natural environment of the South Korean nation, which occupies the southern half of the Korean peninsula. Environment - current issues: air pollution in large cities; water pollution from the discharge of sewage and industrial effluents; acid rain; drift net fishing Forests were cleared over many centuries for use as firewood and as building materials. However, they have rebounded since the 1970s as a result of intensive reforestation efforts. The country's few remaining old-growth forests are protected in nature reserves. South Korea also has twenty national parks. One of the world's most interesting wildlife sanctuaries has developed in the DMZ, having been virtually untouched since 1953. The uninhabited zone has become a haven for many kinds of wildlife, particularly migrating birds.
Asian Dust is a meteorological phenomenon which affects much of East Asia year round but especially during the spring months. The dust originates in the deserts of Mongolia, northern China and Kazakhstan where high-speed surface winds and intense dust storms kick up dense clouds of fine, dry soil particles. These clouds are then carried eastward by prevailing winds and pass over China, North and South Korea, and Japan, as well as parts of the Russian Far East. Sometimes, the airborne particulates are carried much further, in significant concentrations which affect air quality as far east as the United States.
The four big pollution diseases of Japan were a group of man-made diseases all caused by environmental pollution due to improper handling of industrial wastes by Japanese corporations. The first occurred in 1912, and the other three occurred in the 1950s and 1960s.
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 and health problems.
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life. Some metals are toxic when they form poisonous soluble compounds. Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain form. In the case of lead, any measurable amount may have negative health effects. Often heavy metals are thought as synonymous, but lighter metals may also be toxic in certain circumstances, such as beryllium and lithium. Not all heavy metals are particularly toxic, and some are essential, such as iron. The definition may also include trace elements when in abnormally high doses may be toxic. An option for treatment of metal poisoning may be chelation therapy, which is a technique which involves the administration of chelation agents to remove metals from the body.
Environmental toxicology is a multidisciplinary field of science concerned with the study of the harmful effects of various chemical, biological and physical agents on living organisms. Ecotoxicology is a subdiscipline of environmental toxicology concerned with studying the harmful effects of toxicants at the population and ecosystem levels.
Fish and shellfish concentrate mercury in their bodies, often in the form of methylmercury, a highly toxic organomercury compound. Fish products have been shown to contain varying amounts of heavy metals, particularly mercury and fat-soluble pollutants from water pollution. Species of fish that are long-lived and high on the food chain, such as marlin, tuna, shark, swordfish, king mackerel and tilefish contain higher concentrations of mercury than others.
The Camelford water pollution incident involved the accidental contamination of the drinking water supply to the town of Camelford, Cornwall, in July 1988. Twenty tonnes of aluminium sulphate was inadvertently added to the water supply, raising the concentration to 3,000 times the admissible level. As the aluminium sulphate broke down it produced several tonnes of sulphuric acid which "stripped a cocktail of chemicals from the pipe networks as well as lead and copper piping in people’s homes." Many people who came into contact with the contaminated water experienced a range of short-term health effects, and many victims suffered long-term effects whose implications remained unclear as of 2012. There has been no rigorous examination or monitoring of the health of the victims since the incident, which is Britain's worst mass poisoning event. Inquests on people who died many years later found very high levels of aluminium in the brain. Dame Barbara Clayton led a Royal Commission on Environmental Pollution enquiry into the incident.
Suicide in South Korea is the 10th highest rate in the world according to the World Health Organization, as well as the second highest suicide rate in the OECD after Lithuania.
The anti-nuclear movement in South Korea consists of environmental groups, religious groups, unions, co-ops, and professional associations. In December 2011, protesters demonstrated in Seoul and other areas after the government announced it had picked sites for two new nuclear plants.
Yunnan Jinding Zinc Corporation Ltd., founded in 2003, is a subsidiary of Sichuan Hongda, a larger mining firm which itself is a subsidiary of the Hanlong Group. It operates a mine and smelter near Jinding in Lanping County, Yunnan with an annual capacity of over 100,000 tons of zinc.
