Carbon nanoparticles are carbon nanotubes, which as a synthetic nanoscale material are only one of hundreds of carbon containing nanoscale particulate matter in the air. The toxicity of this material is not representative of the impact of all carbon nanoparticles on air quality.
There are tens of thousands of carbon nanoparticles in the air. For example, in PM1, submicron, or nanoscale, carbon containing particles make up fifty percent of the total.
Carbon Nanoparticles - The Dangers Nanoparticles are approximately 1-100 nanometres in size (10,000 times smaller than the diameter of a human hair). Nanoparticle research has potential applications in areas such as diagnostics, cancer detection and targeted drug delivery. However, the safety of nanoparticles has been questioned, especially since the toxicity of nanoparticles in sunscreen oils has been found and it is difficult to evaluate the reaction properties of nanoparticles, so their functional properties are not yet clear. Scientists have also shown that nanoparticles can cross cell membranes and cause harm to other healthy cells.
