“…However, the toxicological assessments of CNTs should take into consideration the effect of redox-active iron, used as a catalyst during their synthesis and present as metallic clusters, entrapped within the pMWCNT, or as metal residues in their surface (Bello et al, 2010).…”

“…Studies intended to simulate active sanding processes tend to use motorized industrial or laboratory scale sanding equipment, and a few studies of manual sanding with commercial sandpaper have even been published. [2][3] Release during and after other manufacturing processes such as drilling, [4][5] grinding, 2 cutting/sawing, 2, 6-7 and shredding 8 has also been explored. Most research efforts that study the effects of abrasion on release of ENMs from nanocomposites are concerned with potential inhalation exposures, and therefore they have tended to focus exclusively on aerosol and airborne particle analysis.…”

“…Bello i wsp. w kolejnej pracy (2010) [14] opisali badanie oceniające narażenie na nanorurki węglowe podczas obróbki mechanicznej (wiercenie) kompozytów hybrydowych zawierających nanorurki węglo-we, takich, jakie były już stosowane w poprzednim badaniu (2009) [13]. Pomiary wykonywano podobnie jak w wyżej opisanej pracy: w miejscu uwalniania się cząstek oraz w strefie oddychania pracownika.…”

“…Mierzono stężenie masowe i liczbowe cząstek, wymiarowy rozkład cząstek (z zakresu 5 nm--20 μm) oraz stężenie powierzchniowe. W porównaniu z procesami ścierania/cięcia opisanymi w pracy [13] podczas wiercenia zaobserwowano różnice w rozkła-dzie wielkości i morfologii uwalnianych cząstek, stęże-niu włókien, a także agregatów nanorurek węglowych obecnych w powietrzu środowiska pracy [14].…”
