Toroku Arsenic Disease
was a disease resulting from air and water pollution from a refinery at a mine at Toroku, located in Takachiho, Nishiusuki District, Miyazaki, Japan. It emitted arsenic-containing air, resulting in patients with chronic arsenic poisoning producing skin changes, skin cancers and sometimes lung cancer. The Sumitomo Metal Mining Co., Ltd., which bought the right of mining, was sued by the patients for health damage, but 15 years later, the lawsuit ended with a compromise. History The pollution at Toroku dates back to 1690 according to A Table of Public Hazards of Japan *Between 1920 and 1941, and between 1955 and 1962, arsenic production was conducted at a refinery which produced smoke, which stayed deep in V-shaped valleys. Workers and inhabitants developed chronic arsenic poisoning, and five died in a family of seven in succession. * In 1925, horses and cows died possibly due to pollution, recorded a veterinarian. * In 1967, the mining rights went from a small factory to Sumi ...

The nasal septum () separates the left and right airways of the Human nose, nasal cavity, dividing the two nostrils. It is Depression (kinesiology), depressed by the depressor septi nasi muscle. Structure The fleshy external end of the nasal septum is called the Human nose#Cartilages, columella or columella nasi, and is made up of cartilage and soft tissue. The nasal septum contains bone and hyaline cartilage. It is normally about 2 mm thick. The nasal septum is composed of four structures: * Perpendicular plate of ethmoid bone * Vomer bone * Septal nasal cartilage * Maxillary bone (the crest) The lowest part of the septum is a narrow strip of bone that projects from the maxilla and the Palatine bone, palatine bones, and is the length of the septum. This strip of bone is called the maxillary crest; it articulates in front with the septal nasal cartilage, and at the back with the vomer. The maxillary crest is described in the anatomy of the nasal septum as having a maxill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Disasters In Japan
A biophysical environment is a life, biotic and Abiotic component, 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 Ecoregion#Terrestrial, terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term '':wikt:environment, 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. Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollution In Japan
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. Japan is the world's leading importer of both exhaustible and renewable natural resources and one of the largest consumers of fossil fuels. Environment dete ...

Lung Cancer
Lung cancer, also known as lung carcinoma (since about 98–99% of all lung cancers are carcinomas), is a malignant lung tumor characterized by uncontrolled cell growth in tissue (biology), tissues of the lung. Lung carcinomas derive from transformed, malignant cells that originate as epithelial cells, or from tissues composed of epithelial cells. Other lung cancers, such as the rare sarcomas of the lung, are generated by the malignant transformation of connective tissues (i.e. nerve, fat, muscle, bone), which arise from mesenchymal cells. Lymphomas and melanomas (from lymphoid and melanocyte cell lineages) can also rarely result in lung cancer. In time, this uncontrolled neoplasm, growth can metastasis, metastasize (spreading beyond the lung) either by direct extension, by entering the lymphatic circulation, or via hematogenous, bloodborne spread – into nearby tissue or other, more distant parts of the body. Most cancers that originate from within the lungs, known as primary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bowen's Disease
Squamous-cell skin cancer, also known as cutaneous squamous-cell carcinoma (cSCC), is one of the main types of skin cancer along with basal cell cancer and melanoma. It usually presents as a hard lump with a scaly top but can also form an ulcer. Onset is often over months. Squamous-cell skin cancer is more likely to spread to distant areas than basal cell cancer. When confined to the outermost layer of the skin, a precancerous or ''in situ'' form of cSCC is known as Bowen's disease. The greatest risk factor is high total exposure to ultraviolet radiation from the sun. Other risks include prior scars, chronic wounds, actinic keratosis, lighter skin, Bowen's disease, arsenic exposure, radiation therapy, tobacco smoking, poor immune system function, previous basal cell carcinoma, and HPV infection. Risk from UV radiation is related to total exposure, rather than early exposure. Tanning beds are becoming another common source of ultraviolet radiation. Risk is also elevated in cer ...

A Table Of Public Hazards Of Japan
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...
