fireworksStrontium salts are used in fireworks to produce crimson red flames after ignition and it is not possible to get into direct contact with airborne strontium carbonate nanoparticles during the burning process. Homeopathic administered strontium carbonate could be considered as a targeted approach for medical purposes but it is not clear if the medical products contain micro- or nano-scaled strontium carbonate or even a mixture of both.
Is there any risk from this material to humans and the environment?
Little information exists on the effects of strontium carbonate nanoparticles on humans or the environment. This may be due to the relatively small number of applications for this material. Laboratory studies have shown that different cell types can take up strontium carbonate nanoparticles and high doses may lead to cell death. However, no harmful effects of strontium carbonate nanoparticles have been found in whole animal studies.
Regarding the environmental behaviour of strontium carbonate nanoparticles, there are currently no data available.
