What happens to asbestos when it enters the environment? iu
Asbestos fibers can alter the air or water from the breakdown of natural
deposits and manufactured asbestos products. Asbestos fibers do not
evaporate into air or dissolve in water. Small diameter fibers and
particles may remain suspended in the air for a long frme and be carried
long distances by wind or water before settling down. Larger diameter
fibers and particles tend to settle more quickly.
Asbestos fibers are not able to move through soil. Asbestos fibers are
generally not broken down to other compounds and will ronain virtually
unchanged over long periods. •
How might I be exposed to asbestos?
We are all exposed to low levels of asbestos in the air we breathe. These
levels range fem 0.00001 to 0.0001 fibers per milliliter of air and
generally are highest in cities and industrial areas.
People working in industries that make or use asbestos products or who
are involved in asbestos mining may be exposed to high levels of
asbestos. People living near these industries may also be exposed to high
levels of asbestos in air.
Asbestos fibers may be released into the air by the disturbance of
asbestos-containing material during product use, demolition work,
building or home maintenance, repair, and remodeling. In general,
exposure may occur only when the asbestos-containing material is
disturbed in some way to release particles and fibers into the air.
Drinking water may contain asbestos from natural sources or from
asbestos-containing cement pipes.
How can asbestos affect my health?
Asbestos mainly affects the lungs and the membrane that surrounds the
lungs. Breathing high levels of asbestos fibers for a long time may result
in scar-like tissue in the limgs and in the pleural membrane (lining) that
surrounds the lung. This disease is called asbestosis and is usually foimd
in workers exposal to asbestos, but not in the general public. People
with asbestosis have difficulty breathing, often a cough, and in severe
cases heart enlargement. Asbestosis is a serious disease and can
eventually lead to disability and death.
Breathing lower levels of asbestos may result in changes called plaques
in the pleural membranes. Pleural plaques can occur in workers and
sometimes in people living in areas with high environmental levels of
