The exhaust of vehicles does not produce fly ash. Fly ash is a byproduct of burning coal, not gasoline or diesel fuel.

The natural sink of the stratospheric ozone layer is not SO2, HCF, or Sulphur flux of oceans. It's Freons. Freons are chlorofluorocarbons (CFCs) that have the potential to destroy the ozone layer.

Substances that are easily broken down into harmless substances by decomposers are termed biodegradable. Non-biodegradable substances cannot be broken down by natural processes.

The concentration of greenhouse gases is high today because of all of the above: use of refrigerators, increased combustion of oil and coal, and deforestation. All these activities release greenhouse gases into the atmosphere.

CO2 is usually not classified as an atmospheric pollutant. While it is a greenhouse gas and contributes to global warming, it is not considered a pollutant in the same way as CO, NOx, and SO2, which have direct harmful effects on human health and the environment.
