That there are pollutants in the atmosphere is one thing; where it is coming from is another.
Graphene, for example, might be in the atmosphere from the burning of coal.
Other metals can be there from refineries and founderies.
However, surfactants won’t survive being burnt or at high temperatures.
They could be in the atmosphere by dumping sewage from Airplanes or from other sources.
There are needed more detailed studies as to the sources, not just the contents of pollutants.
