 * Well, I thought that dust explosions of carbon nanotubes were a non-obvious hazard... A lot of the more interesting facts of the article are a bit too technical for a DYK hook (two examples: filters are better at capturing smaller nanoparticles because they have more Brownian motion; nanoparticle size doesn't affect the combustion rate because volitilization is so fast that the combustion itself is the rate-limiting step).  ALT1 below emphasizes the dust explosions more, ALT2 is along the lines of what you suggested.  John P. Sadowski (NIOSH) (talk) 05:31, 21 July 2017 (UTC)
 * ALT1: ... that the health and safety hazards of nanomaterials include not only inhalation exposure (pictured) but also dust explosions?
 * ALT2: ... that in animal studies of the health and safety hazards of nanomaterials, carbon nanotubes had similar inhalation exposure effects (pictured) to asbestos?
 * I'll pass ALT2 if you make it "similar ... to" rather than "similar ... as", which I find too grating. The prose style is still too ponderous and wordy for my taste but that shouldn't be a blocker at DYK which is for new material.  (I was amused by an item in the news this morning about a hyper-local multi-passenger pooled vehicle – a bus!)  I checked the hook length and it's 154 which is inside the DYK limit of 200.  Andrew D.

 * Symbol confirmed.svg Thanks -- we're good to go then. I'm still interested in dust hazards myself -- for example, the metal dust in the London Underground -- and so will continue to follow the progress of the topic. Andrew D. (talk) 09:00, 21 July 2017 (UTC)
