Today, most people know the dangers of inhaling asbestos
fibres. When the asbestos fibres become airborne and breathe in by people into
their lungs, it can lead to a number of serious illnesses and conditions like
malignant lung cancer, mesothelioma and asbestosis.
The two minerals that are mostly responsible for the
hazardous nature of asbestos are amosite and crocidolite because of their long
staying power in a person’s lungs. As they stay longer in the lungs, they
become irritants, causing tumors and cancers to develop. As the body attempts
to rid and attack the foreign substance, it repeatedly fails. The repeated
failure will eventually lead to mutation as the cells try to adapt. The
uncontrolled mutation will make the cells form into cancer.
Did you know that the earliest recorded use of asbestos was
estimated to be 4,500 years ago? Archeologists found out that asbestos were
being used in strengthened earthenware pots and cooking utensils.
In most counties, asbestos is banned and usually disposed of
as hazardous waste in landfills. But are you aware that asbestos can be
recycled and turned into a harmless silicate glass? By heating the asbestos up
to 1000-1250 degrees Celsius, a mixture of non-hazardous silicates are produced;
then to transform them into silicate glass, they are heated at temperatures
above 1250 degrees Celsius.
