Generation of NPS for Exposure Experiments from Copper Acetylacetone.
Moravec, P. ; Schwarz, J. ; Vodička, P. ; Kupčík, Jaroslav ; Švehla, J.
Particles containing copper are emitted from smelters, iron foundries, power stations, and municipal incinerators (WHO, 1998) and also from brake linings during breaking, Kukutschová et al. (2011). Nanoparticles (NPs) of copper are ingredients in polymers, inks, and bioactive coatings inhibiting the growth of microorganisms, Cioffi at al. (2005), and CuO NPs has been used in antimicrobial textiles, Gabbay and Borkow (2006), therefore they can be easily inhaled. Even though CuO NPs were found highly toxic, Karlsson et al. (2008), in vivo studies of their toxicity are still rather rare. In this work we tested a method of long lasting nanoparticle generation from copper acetylacetonate (CuAA) for use in follow up exposure experiments with laboratory animals. The exposure chamber for inhalation experiments was constructed in the Institute of Analytical Chemistry AS CR (Večeřa et al., 2011) and some methods of NPs generation for these experiments were already tested in our laboratory (Moravec et al., 2015, Moravec et al., 2016).
