2. Asbestos is a term for a group of naturally occurring
fibrous minerals that have been used in a wide range of
cement-based building products
They are made mainly of silicon and oxygen, but they
also contain other elements. There are 2 main types
of asbestos:
Chrysotile asbestos, also known as white asbestos, is the
most common type of asbestos in industrial applications
Amphibole asbestos fibers are straight and needle-
like.

3. The method of choice for the quantitative determination of
asbestos in ambient air and water
is transmission electron microscopy (TEM) with
identification by energy-dispersive X-ray
analysis and selected-area electron diffraction (TEM/SAED)
DETERMINATION
Analysis by TEM/SAED is
costly, and preliminary screening with TEM alone
which has a detection limit of below
0.1 million fibres per litre (MFL) in water is therefore
often used.

4. No amount of asbestos is considered safe. Products
that contain greater than 1 percent of asbestos
minerals are considered to be asbestos-containing.
The more asbestos you are exposed to, the more
likely you are to get an asbestos disease
Usually, it takes years of continued exposure to high
levels of asbestos—like those in an industrial
environment—to cause health problems

7. Mesothelioma
Mesothelioma is a cancer which affects the lining of the
lungs (pleura) and the lining surrounding the lower
digestive tract (peritoneum). It is almost exclusively related
to asbestos exposure and by the time it is diagnosed, it is
almost always fatal.
Asbestos-related lung cancer
Asbestos-related lung cancer is the same as lung cancer
caused by smoking and other causes. It is estimated that
there is around one lung cancer for every mesothelioma
deat

8. Asbestosis
Asbestosis is a serious scarring condition of the lung that
normally occurs after heavy exposure to asbestos over many
years. This condition can cause progressive shortness of
breath, and in severe cases can be fatal.
Pleural thickening
Pleural thickening is generally a problem that happens
after heavy asbestos exposure. The lining of the lung
(pleura) thickens and swells. If this gets worse, the lung
itself can be squeezed, and can cause shortness of breath
and discomfort in the chest
