(It is a natural range of fluid consisting of silica crystals of salt minerals) CRYSTALLINE HYDRTATED SILICATES), which is a very small fibers do not see with the naked eye and need a microscope; to be able to see it. It characterized by asbestos fibers such as strong and hardy and resistant to heat and combustion, as well as resistance to acids and friction. There are two families of asbestos fibers differ in quite Joasma:1. Ahalzonyat family or spirochetes (serpsntine family):Featuring family fibers as corrugated and flexible, and this is more prevalent in industrial products fiber, and fortunately that this family is less serious, and this family type named (chrysotile CHRYSOTILE), white fibers corrugated, and represents about 90% of asbestos in industrial products.2. family (amphibole family):The fibers of this family are characterized as being straight and dry and brittle, and these fibers are less prevalent in the industrial products and more dangerous, and types of fibers (amosite amosite), which are either brown or gray, and fiber (Alkrukire crocidolie) blue and fibers.As used asbestos?Previous to the properties of asbestos fibers has been combined with other materials in the following industries:1. insulators: such as insulated pipes, insulation bricks and cement asbestos2. shipbuilding.3. power units and refineries.4. construction companies for the production of building materials fire-resistant and sound-proofed and heat and restoration materials and material surfaces.5. textile industries such as: manufacturing gloves and blankets.6. brakes and gears cars.7. electrical wiring.8. hair dryers.9. home baking ovens toasters)).How asbestos causes the disease?The harmful effects of asbestos fibers occur if inhaled or swallowed, and this does not happen if the asbestos fibers combined well with other materials so that these materials prevent the spread of these fibers in the air, and is a high risk when exposed to these materials for cracks or fall, rising asbestos fibers in the air; where inhale or swallow without feeling person; because of their small fiber size, and I've had exposure to asbestos fibers in the past only in the factories going, but now occurs exposure to this dangerous fiber in schools, homes and public buildings such as hospitals, where he used large quantities of materials containing asbestos in the construction of schools in the period from 1946 to the year 1972 in the United States, and the cracking of this article leads to the spread of asbestos fibers in the air is very high and dangerous proportions, affecting the health of school children and their personnel, and after reviewing numerous studies of the US Congress confirmed that there is no safe limit for exposure to asbestos fibers; because it is very dangerous fibers, particularly on children's health.It was found that the severity of the injury depends on the asbestos fiber concentration in the air and the duration of exposure to the fibers and in response the same person, as vulnerable varies depending on the size and shape of the fiber and the degree of solubility, Volaav family Ahalzonyat (serpentine family) the advantage of being flexible and corrugated; so are held in the upper airways (nose and nasopharynx, larynx and trachea), and it is being driven by cilia mucous, and if you reach the fibers into the lungs can easily be removed because they are more soluble; therefore this type does not cause tumors cavity malignant, while the straight fiber stiff for a family (amphibole family), they lined up in the air direction to reach the depths of the lungs and thus causing tumors cavity malignant, long fibers of more than 8 mm, less than 0.5 mm high and be more serious, it is worth mentioning that the two families fibers are causing lung fibrosis.And it works asbestos - unlike all the dust is other organic that cause fibrosis in the lung - creator of the tumors (tumor initiator), as well as a catalyst for tumors (tumor promoter), along with the Tdamj asbestos fibers with toxic chemicals are carcinogens (such as found in cigarette smoke) leading to increased the incidence of malignant lung tumors, and in one study found that exposure to asbestos fibers only lead to increased 5 times in the incidence of lung cancers, but exposure to asbestos with cigarette smoke leads to increased incidence 55 times.What are caused by the inhalation of asbestos diseases?1. fibrosis cavity Limited (Localized Fibrous Plaques), and rarely occurs in cirrhosis of the cavity Diffuse Fibrosis). )2. edema Alblora. (Pleural Effusion)3. metastatic lung fibrosis (Asbestosis) which leads to a drop in the Yemeni effort of the heart due to high pressure in the pulmonary circulation.4. tumors serous membranes malignant Mesothelioma)) that occur in the crystal membrane or peritoneum, and this rare tumor in people who are not exposed to asbestos fibers and increases the incidence upon exposure to 1000 times.5. malignant lung tumors (Bronchogenic Carcinona) and more than five times the rate for natural person.6. tumors outside the lung, such as tumors of the larynx, stomach, intestine and rectum.What are the symptoms?These symptoms usually do not begin to emerge from 10 years before exposure, and can show after 40 years or more; because the harmful fibers that remain in the lung for life, and symptoms include the following:? Shortness of breath and usually begins with the effort then becomes present at rest.? Cough with sputum? Chronic stress? The right part of the heart muscle failure (Right Sided Heart Failure) as a result of high-pressure pulmonary circulation as a result of cirrhosis of the lung, which leads to swelling of the body (Oedema) with ascites in the peritoneum (Ascitis).
It remains the last question which is the solution to this problem?The solution lies in preventing the use of asbestos in various industries, and has been to prevent its use in several industries including insulation pipes and building materials, and even be prevented in all industries, the periodic disclosure of the factory workers become the only way to save these workers from the disease do not treat her. As for those who live in places where the use of asbestos in construction, the danger lies in the event of cracks in the material or try to remove them, and here we must be the same person presents a specialized health places to conduct the necessary tests to make sure the presence of asbestos fibers in the lung, and here is the solution set insulating layer or cover these walls to prevent the spread of asbestos fibers, and warns - just - of trying to remove these materials; because removal could cause the most dangerous to human health.Newspapers around the world carried Finally, including Arab newspapers, an advertisement warning afraid many of our readers, with most of them did not understand the meaning of it. According to the announcement verbatim as follows: * If you have been exposed to asbestos or products containing asbestos manufactured or distributed or sold or possessed by Federal Mogul company ... which is under reorganization and bankruptcy in the United States, Britain and procedures, it may be you right to participate in those measures *.Text explains that the manufacturer of the asbestos (asbestos) sought by the US and British courts to approve the request, the establishment of compensation for those affected by the potential of its products Fund. The declaration calls from anyone, anywhere in the world, has a claim against the company * respect to exposure to asbestos or products containing it manufactured by the company or its agents, to vote to accept or reject the compensation plan *. It sets out how to get the details and vote * prior to the court hearing to make a decision on 9 December (December 2004) *.The announcement carries with it a lot of connotations. It confirms, once again, on the seriousness of asbestos, which was used until recently common in Arab countries. When launched * Environment and Development * wide campaign against asbestos in 1997, accused us manufacturers in Lebanon, Saudi Arabia and the UAE bias. One argument put forward by defenders of the asbestos that * does not prove as damaging to health, if the body entered the water, because the harm is certain respiratory tract do not *. That argument flimsy to justify the use of asbestos pipes in water systems have been used. It is ironic that the Lebanese Ministry of Environment supported this position at the time, Vnscherna pictures of children playing on the pieces of pipes asbestos broken and discarded on the roadside in the workplace, and we said that when volatilized dust in the air can not ask people to dissolve in water instead of breathing with air, because it is invisible. It is also ironic that the asbestos brokers based their time to fragmentary reports from the World Health Organization, without that the organization correct their information.Fortunately, the asbestos was out of use now in most Arab countries, with or without the law, because the awareness campaigns have led to his rejection by the people and officials alike. However, some of his factories which stopped, including asbestos factory in northern Lebanon, are still stored manufactured pieces that hit by the recession, and the waste of raw materials, outdoor, posing a serious threat to people. While you need remove one square meter of the panels or walls of the asbestos used in the old buildings in Europe to prior authorization, before being allowed to specialized companies licensed to do the work and the burial of waste as toxic waste, we are dealing with the remnants of asbestos still in our countries freely without restrictions.May be the most prominent sign of the announcement, we began our article with excerpts of it is to give people informed and involved in the decision right. Before the courts accept the liberalization of the companies responsible for possible damage claims from asbestos, imposed on these companies place your ad around the world to grant any right to object and victim compensation. It gave the public a long time to allow him to submit an objection, simple measures is complex, instead of smuggling * * Case of trading. This contrasts completely with that practiced by most of our countries, where the environmental impact report for the project remain, if you originally found, hidden in the drawers do not allow people affected to look at it, arguing it a state secret. The polluting industries in the Arab world live on borrowed time phase, between the law of the jungle and the rule of law. But it can not continue indefinitely to evade its responsibilities.(Various sources).Reuters news agency published on its pages on the Internet news report from Britain, referring to the large size of the victims of asbestos in Britain, which reached four thousand people a year, and then became it represents the biggest killer of British men less than 66 years, in over twenty years years, it is worth mentioning that the European Union had recommended in July last year to ban all current uses of asbestos, the Member States and gave a chance until 2005 to complete it.In addition, it has published a page environment Al-Ahram newspaper story on 27 June that there was 45 people working in one sector companies in Egypt - which manufactures many of the products of asbestos - have suffered cavity cancer and peritoneal due Chemicals asbestos are inhaled, high prevalence of injuries resulting from asbestos has led to the establishment of numerous legal claims for compensation and the emergence of the movement of civil institutions to defend the rights of these victims to the companies, and calls for the prohibition of the use of that substance devastating human lung, and then was this article in order to know what is asbestos and its uses and its impacts health:http: //ar.wikipedia.org/wiki/%D9%85%D8%B3%D8%AA%D8%AE%D8%AF%D9%85: Walaa _...http://www.lightpollution.org.uk/dwnLoads/Asbestos_JoM1976.pdfA good idea of how to get rid of this article:American University of Beirut began to apply the safe way to get rid of asbestos "Asbestos", being a private carcinogen when volatilization of atoms in the air.And notes the way you put the environmental health and safety director of risk management at the University Azmi Imad, and Engineer in buildings and property department Sohail Itani, was buried "asbestos" in huge blocks of cement last for thousands of years and bears all the climate changes.And the University has prepared three concrete cubes containing "asbestos", and assumed the heavy trucks loaded cubes for transport to the landfill Bsalim under the supervision of the Ministry of Environment and cooperation between them and the university.Ashraf and Environment Minister Dr. Omar Al-Halabi adviser on the process, "hoping" that "step by the university contribute to raising the level of awareness of the seriousness of the pollution of the environment and find solutions to him."Emad Azmi explained that in the absence of specialized disposal of asbestos landfills remain the means initiated by the university, the solution easier and cheaper.Imad stressed that concrete cubes containing asbestos is safe, and can be used to strengthen the collapse-prone mountains.He stressed expert from the environmental health department at the American University Said Najjar, that this method can be an example for locally and regionally.The use of fungi to absorb asbestos fibers from the ground and eliminate the dangerMost of the world's countries imposed a ban on production and use of asbestos in construction, insulation and streets in view of its high toxicity against the environment and against human basis. But environmental health scientists know very well that the asbestos problems, especially asbestos lung disease and other construction workers, is not about a period of asbestos use, but in twenty years the period after that. This is because the symptoms of asbestos diseases do not appear until after 15 to 20 years of human exposure to it. And like Germany it has banned the use of asbestos for nearly 10 years, but to account for the increased incidence of asbestos lung disease after 15 years from now to reach its peak in 2020. This means that it is necessary to eradicate the existence of industrial asbestos from the environment to human can eliminate late illnesses.That is why the Italian researcher Vobana Paes and his colleague Sylvia Biroto have suggested that the use of fungi in the contaminated areas in order to offset the impact of asbestos. It is believed that Vobana iron and other metal ions, necessary for human life, constitute the brighten fiber asbestos is very dangerous to the environment and the human factor. And it is proven through these experiences that these metal ions play a crucial role in the toxicity of asbestos and long-term impact on the environment.Because these ions launches many Radical able to resurrect the turmoil in the transfer of genetic information in the cells, which consequently leads to stimulating the emergence of the cancerous growth.And he held Voban and his colleague experiments demonstrate that the withdrawal of iron ions to brighten asbestos fibers can reduce the impact of cancer of the catalyst clearly. Can fungi that grow on the soil to undertake the task of pulling iron from asbestos efficiently estimated by Italian researchers. As some types of fungi need to continue to iron metabolism cycle and kept some of the material in their bodies.This is not to mention the roots of filamentous fungi plexiforme able to expand vertically and horizontally in the soil.Researchers Italians try many types of fungi and reached kinds of them can co-exist and grow spectacularly on the metal ions on the surfaces of asbestos account. This fungus was able to splice root nematodes with and within the asbestos fibers that absorb the harmful ions such as iron.And transformation of asbestos due to the fungus fibrous material different is able to spread, as asbestos roofs turned, as expected, to the case of ionic ineffective, it may not be conducive to cancer.Through Vobana he hopes that this discovery is used in the development of biological method for purifying contaminated land asbestos. According to statistics of the Ministry of Health to the death of German 110 thousand people work the influence of asbestos diseases since 1980 and recorded a statistic in 2001 occurrence of 931 deaths due to these diseases, but that the ministry estimates that the number of victims rises to 20 thousand in 2020==================================================Covenant sponsored symposium «damage asbestos» RiyadhSPA - RiyadhHis Royal Highness Prince Sultan bin Abdulaziz Al Saud, Crown Prince, Deputy Prime Minister and Minister of Defense and Aviation and Inspector General Symposium // damaged asbestos and disposal methods // organized by the General Directorate of Military Works, Ministry of Defense and Aviation, in cooperation with King Saud University and the General Presidency of Meteorology and environment with the participation of all relevant sectors during the period from 17 to 18 Muharram corresponding to 26 to Jan. 27 at the King Faisal conference Hall, Riyadh Intercontinental Hotel.This seminar is the first of its kind in the UK where he aims to identify the health effects of this article health and procedures to deal with them and management, as the symposium will address the need to increase community and technical awareness is required to deal with asbestos and that the seminar will not overlook the need to review domestic and international experiences in dealing with asbestos.http://www.alyaum.com/issue/article....12631&I=552400It is noted that passed two resolutions of the Council of Ministers No. 1419 and 1422 that sought to stop the use of asbestos and to prevent and put it in the specification and prevent the import and export and processing as well as the replacement of asbestos in buildings and water systems, material disposal and the continuation of the necessary studies about this article to gravity healthy and environmentally.The General Directorate of Military Works, Ministry of Defense and Aviation and General Inspection at the forefront of those who began in the activation of this decision which implemented a number of the disposal of asbestos projects are being carried out a number of other ones now.
