Thanks John.

There have been a few designs for fibre monitors over the years, as I’m sure you are aware. While I was working for HSE in the UK in the 1990′s we were involved in the development of a device that ended up not taking off.

Whether your device (and I’m beginning to wonder whether it was the forerunner of the HSE instrument) would work with nanotubes is hard to tell without further details – would love it if you could dig some up.

In the 1970s I was involved in developing and testing a novel instrument I had devised for monitoring and size classifying airborne asbestos fibres. The impression I received at the time was that one way asbestos fibres presented a risk to health was because the size and shape enabled them to penetrate through the walls of lung membranes and cause irritation. It seems to me that the release of nanofibres into the air (in homes or workplaces) could equally present risks to health. I wonder whether this has received due consideration.

I published the work I did on the Fibre Monitor as: “A novel instrument to monitor and size classify airborne fibres in the respirable size range” Electrostatics ’91 IoP Confr Series 11 8 p169. Have far the approach would go towards working with nanofibres with the advantages from technology improvements since the mid 1970s would need proper consideration.

I recently finished a video for the Museum of Life and Science in Durham, NC that asks the same question: Are Carbon Nanotubes the Next Asbestos? I visited Dr. Jamie Bonner at NC State to inquire about his work on the toxicology of CNT’s.

You can view the video on the Museum’s website:

[...] Asbestos-like nanomaterials – should we be concerned? It seems that when the possible downsides of nanotechnology are broached, it doesn’t take long for the “A” word to surface. But what is the truth—if any—behind comparisons between nanomaterials and asbestos? From January 2009. [...]
