There are 6 kinds of minerals in 2 categories, including serpentine asbestos, hornblende asbestos, actinolite asbestos, amphibole asbestos, chrysotile asbestos and tremolite asbestos. The hazards of asbestos to human body are:
1. Because asbestos fiber can cause diseases such as asbestosis and pleural mesothelioma, many countries have chosen to completely ban the use of this dangerous substance, and some countries are checking the dangers of asbestos.
Asbestos itself is not toxic. Its greatest harm comes from its dust. These tiny dusts will be attached and deposited in the lungs after being inhaled into the human body, causing lung diseases. Asbestos has been confirmed as a carcinogen by the International Center for Research on Cancer.
On the other hand, tiny asbestos dust flies into the air and is inhaled into human lungs. After an incubation period of 20 to 40 years, it is easy to induce lung diseases such as lung cancer. In Europe, it is predicted that by 2020, 500,000 people will die of lung cancer caused by asbestos pollution. In Japan, it is predicted that 654.38+10,000 people will die by 2040.

In addition, a survey conducted by the British Broadcasting Corporation (BBC) and the International Union of Investigative Journalists found that the international asbestos industry has been exporting asbestos to developing countries, and these countries often lack occupational safety regulations.
Asbestos is very popular in developing countries because of its low price, especially in the construction industry. Used for making fireproof, heat-insulating and sound-insulating building materials such as fireproof roofs and water pipes.
Blue and brown asbestos has been banned all over the world, because there is a lot of evidence that they can cause respiratory diseases and cancer, and lead to death. Many scientists oppose the theory that asbestos can be used safely. They quoted the World Health Organization as saying that white asbestos is also a known carcinogen, which may cause cancers such as lung cancer and mesothelial cancer.
White asbestos has been banned in EU countries, but it is still used in India, Russia and other countries. A senior scientist of WHO said that he personally thought that the exploitation, export and use of white asbestos should be banned all over the world now.
