Health risks posed to people who work with tiny fibres used in manufacturing industries could be reduced, thanks to new research.
Research into the health risks posed by nanofibres - used to strengthen objects from tennis rackets to airplane wings - has pinpointed the lengths at which these fibres are harmful to the lungs.
Health risks Nanofibres, which can be made from a range of materials including carbon, are about 1,000 times smaller than the width of a human hair and can reach the lung cavity when inhaled.
This may lead to a cancer known as mesothelioma, which is known to be caused by breathing in asbestos fibres, which are similar to nanofibres.
Length of fibres The University study found that lung cells were not affected by short fibres that were less than five-thousandths of a millimetre long.
However, longer fibres can reach the lung cavity, where they become stuck and cause disease.
We knew that long fibres, compared with shorter fibres, could cause tumours but until now we did not know the cut-off length at which this happened. Knowing the length beyond which the tiny fibres can cause disease is important in ensuring that safe fibres are made in the future as well as helping to understand the current risk from asbestos and other fibres

Super-Strong, High-Tech Material Found to be Toxic to Aquatic Animals
Columbia MO (SPX) Aug 27, 2012
Carbon nanotubes (CNTs) are some of the strongest materials on Earth and are used to strengthen composite materials, such as those used in high-performance tennis rackets. CNTs have potential uses in everything from medicine to electronics to construction. However, CNTs are not without risks. A joint study by the University of Missouri and United States Geological Survey found that they ca ... read more
