What does asbestos dissolve? I ve given out all my points.

Asbestos is harmful to the human body.

Asbestos itself is not toxic, its biggest harm comes from its fibers, which are very small, almost invisible fibers to the naked eye, when these small fibers are inhaled into the human body, they will be attached and deposited in the lungs, causing lung diseases, asbestos has been identified as a carcinogen by the International Agency for Research on Cancer.

Exposure (long-term inhalation) to certain amounts of asbestos fibers or metafibers can cause the following diseases:

1) Lung cancer, gastrointestinal cancer.

2) Mesothelial carcinoma of the pleura or peritoneum.

3) Asbestosis: Scarring of the lungs due to fibrosis of the tissues in the lungs (asbestosis).

4) Asbestos-related disease symptoms tend to have a long incubation period, which may not appear until about 10 to 40 years after exposure to asbestos (15-20 years for lung cancer and 20-40 years for mesothelioma).

3.possible exposure to asbestos.

1) Most of the thermal insulation and sound insulation materials of the ceilings and pipes in some old houses are asbestos products, and when these asbestos materials are dismantled, cut and reshaped, a large number of fine asbestos fibers will be scattered in the air. Some building materials and home decoration materials such as asbestos cement and vinyl plastic flooring can emit fine asbestos fibers.

2) Asbestos cement pipelines acting on water pipelines will cause drinking water pollution.

3) Decorative coatings.

4) Rubber gloves.

4) Pharmaceuticals.

5) Cosmetics, baby powder.

4.Assay method.

Chemically determining asbestos in the environment is difficult. The content of asbestos in the environment is very low, and the asbestos in the atmosphere and water only accounts for a few tens of thousands to thousands of parts of the total suspended solids, which are generally determined by electron microscopy. The metafibers of chrysotile asbestos in the environment have the characteristics of an aspect ratio greater than 3, a tubular shape, and a capillary structure in the tube.

Under the electron microscope, the meta-fibers are magnified by 10,000 to 20,000 times, and their unique morphology is counted, and the relationship between 1 gram of asbestos equals 1 million elemental fibers is converted into a gram of fiber per cubic meter to represent the asbestos content in the atmosphere. The asbestos content in water is expressed as the number of roots per liter of water containing asbestos fibers.

5.Prevention and control measures.

The construction of asbestos and asbestos processing plants is prohibited in the city, and high-efficiency dust removal devices are added to existing factories to strengthen personal protection and regular physical examinations.

Establish emission standards and maximum permissible standards for asbestos.

It is forbidden to spray refractory materials containing asbestos fibers.

It is strictly forbidden to dump asbestos garbage into rivers, lakes and seas.

Asbestos is insoluble in any substance, does not conduct heat or electricity.

Mesoevil is right, you already have 755, and you need 745 to reach 1500 to become a member. It used to take 800 points to achieve **membership, but now the upper limit has been adjusted to 1500, and I also went up today to take a look and found that **member fell to bronze, and there are still a lot of points left to rise back. The customer service's answer was to include the performance ticket in the membership points, and the performance ticket was adjusted to the upper limit because of the high ticket price.

The last question I threw at the customer service was: If I earn enough 1500 points and am promoted to ** member, will you raise the upper limit to 100 million points to beat me back to bronze? He replied that he had not been notified of another increase in the cap.

In the end, I replied to her that I bought each watch last year, and then uninstalled this crapware. I won't mention the old things that were picked on the platform of the Shanghai Film Festival before. Movie tickets alone are much cheaper than it to see glutinous rice, at least in Xuzhou, unless you are promoted to **membership and receive a voucher, it will be cheaper than glutinous rice.

The problem is that you have to throw money into it first, and after smashing it, you find that you can only get vouchers once a month, so why bother.

What do you think, you still need to come out with an extra 745, 745 + 755 = 1500, which is the points you need to save enough.

I can't change it haha, at most I can change a little bit of traffic.

Save more than 2,000 points to exchange for a 30 yuan phone card.

Since March 25, 2016, Tmall points have been gradually closed for use on the computer side, and are only available wirelessly (support scope: mobile version of Tmall app, pad version of Tmall app, mobile version of **app, pad version of **app, client browser).

Hope it helps.
