Asbestos ban

Is it not time that asbestos is prohibited completely?

Mining, manufacturing and the use of asbestos leads to a variety of diseases such as fibrosis, asbestosis, asbestos, lung cancer, pleural plaques, diffuse pleural thickening and the terrible disease, "mesothelioma" warts Asbestos has been used since the time of Greeks itself. Even Persians and the Romans used. It was used to manufacture lamp Wicks and also forged in the clothing worn by slaves.

The Greeks a first realized that something was wrong with asbestos. They found that the lungs of slaves who wore clothes woven asbestos became ill. It is only in the 20th century than medical researchers wakes to the harmful effects of asbestos. In the 1930s, diseases caused by asbestos have been identified in one by one. However, mesothelioma has been only identified in the 1940s. In England, was the first country which prohibits mining, the use and manufacture of asbestos. After that, USA has banned asbestos. If slow efforts, Japan too banned the extraction and use of asbestos. Developed countries have banned or at least strictly regulated with asbestos. However, developing countries are not even showing the effectiveness of the prohibition of asbestos.

Asbestos is a fibrous mineral fire-resistant, resistant to chemicals and flexible. It is therefore a chemical very useful for most people in developing countries. Since they are ignorant about its harmful effects, they use it extensively. Thus, the asbestos industry is a thriving industry in most developing countries. Asbestos industries are owned by rich politicians or the media. Then, they cover research reports and information on the harmful effects of asbestos free. In addition, they even argue that the scientific evidence on the harmful effects of mesothelioma are absent. Thus, this harmful chemical is to be produced and used in a manner very widespread in many countries in development such as the India and China, although the India prohibits all other types of asbestos, it has not imposed any ban on white asbestos. In India, around I0000 mesothelioma cases occur each year.

Another issue facing is that the mesothelioma latency period is very high. Otherwise said, the difference in time between exposure to asbestos fibres and the development of mesothelioma is perhaps even up to 20 to 30 years. Therefore, people spend a lot of jobs in that time, and therefore, they connect mesothelioma so that they are working or living near asbestos industry. The Sweden is the first country to show a decline in the incidence of mesothelioma after a ban of asbestos. It has about 20 cases per million population per year.
Mesothelioma has a huge lag period, medical researchers expect that a large majority of people suffer mesothelioma between 2020 and 2040. In developed countries only, it is expected that more than a million people died of mesothelioma in the next few decades. If this was the case in developed countries, while the situation in developing countries, which have neither banned asbestos or given any security work or as a precautionary measure, is frightening.

A complete ban on mining, manufacturing and use of all types of asbestos, in all countries, is the best solution for this problem.
