An aforementioned study to be realeased in the next issue of the ERJ has already warranted a response from certain members of the scientific community.

The response highlights some of the reasons that could be attributed to the deaths seen as being caused by nanoparticles. There is no denial that some forms of nanoparticles are toxic to humans but there is concern mostly about the working conditions of those in the nanoparticle using factory.

Before respiratory symptoms were noticed in the patients it has come to light that the factory of 70 square metres was unventilated due to a broken ventilation system. Contained no windows and the door was kept shut due to the cold. Apart from this what has become obvious is that the workers were very poorly informed of health and safety and had no real idea about what they were using. As an addition to this the only safety measure sporadically applied was the use of cotton gauze masks, which would have been useless against nanoparticulate substances. So the main concern is that the lack of ventilation allowed incredibly high levels of nanoparticles to build up locally in the factory and this is the cause of the illness seen.

It is maintained by the paper writers that this was not the full problem and that really it was the underlying toxicity of the nanoparticles no matter what that was causing this. Either by entering through the respiratory system or even maybe through the skin or both.

What is certain about this paper and the replies it has already promepted is that it has stirred up much interest and speculation in the nanotoxicologist community. Quite rightly so no matter what technology you use you must always make sure it has no inherent health problems and if it does that its use is correctly regulated.

One of the most important things to overcome with and issue like this is to convey this knowledge in an unbiased way to those who are not specialists  in the field to form their own educated opinions. – CT
