Spheroidal carbonaceous particles (SCP) are indicative of fossil fuel burning, while black carbon and ammonium suggest biomass burning of trees through human activities and/or forest fires.

Finding this type of pollution – known as fly-ash or spheroidal carbonaceous particles (SCPs) – contaminating natural deposits is seen as an indicator of the presence of human influence on the ...

First recorded presence of anthropogenic fly-ash particles in coral skeletons. Science of The Total Environment, 2024; 170665 DOI: 10.1016/j.scitotenv.2024.170665 ...

They confirmed the deposit's age using the presence of European crop pollen as well as tiny grains known as spheroidal carbonaceous particles, which are created by the burning of fossil fuels.

Other examples include natural textile fibres such as cotton and wool, Spheroidal Carbonaceous Particles (remnants of fossil fuels), and brake-wear particles from vehicles - all of which are ...

The proof is their study of the comet ATLAS (C/2019 Y4) approaching the Earth in May 2020 and disintegrated with displaying a major outbreak of the carbonaceous particles.
