Middlesbrough Council confirmed 10 schools in the borough still contain either Chrysotile, Amosite, or
Crocidolite - three types of the mineral also known as "white", "brown" and "blue" asbestos.
There are three main types: Chrysotile (white), Amosite (brown) and
Crocidolite (blue).
A total of 38 of the 57 schools of which the council is responsible for (66 per cent) contain the substance, with 13 containing
crocidolite - the most serious.
Chrysotile fibers, tremolite, amosite, and
crocidolite might be found in the lungs of workers even 30 years or more after their last exposure [9-11].

crocidolite asbestos during mitosis in living vertebrate lung epithelial cells.
There is a dire need to acquaint our workforce with the composition of asbestos material in the form of fibrous silicate minerals actinolite, amosite, anthophyllite,
crocidolite, tremolite and chysolite.
These imports decreased from 1997 when some forms of asbestos, such as
crocidolite and amosite, were prohibited (Park, Choi, Ryu, Park, & Paik, 2008).
Ingestion of chrysotile or
