I don't think so. Various types of organics in gaseous or vapours form are released into the atmosphere. There may some Chemical reaction and there may be possibility to be converted into another form. Biodegradation is not instant phenomena. It need some time, Therefore, I don't think so.

Let us see views if other researchers also.

Thank you Dr. Mohammad for your views.

Well,

Fate of air pollutants is precipitating either as dry deposition or wet deposition, or removed as acid rains, here the question, is bacteria present in atmosphere, and what about life residence time of bacteria and the type of bacteria that affect biodegradation.

Highlight, if the biodegradation processes within atmosphere were occurred, the water vapour and green house gases decayed and may be removed, with no climatic change.

SINCERELY

Thank you Dr. Hussien for your valuable views

I am afraid that air is not a good growing place for microrganisms, so biodegradation kinetic in atmosphere is very low.

Most biodegradation will occur in soil and water.

Thank you Dr. Legorburu for your enlightened comment.

The task of evaluating how biodegradable is a certain chemical compound requires consideration of all environmental compartments. Only with the use of the multi-compartment models simulating coupling between atmosphere, hydrosphere, cryosphere and soil system, we can trace “a history” of the chemical compound migrating from the atmosphere to the terrestrial systems and back to the atmosphere. There are numerous models which can be applied; for the excellent review please see

I believe there is a little or no biodegardation of atmospheric pollutants. This is because of most of the organisms involved in this process are found on the land and in the soil.

The exchange between atmosphere and soil, biodegradation in soil and re-volatilization should be considered in order to answer the original question. For discussion of this topic please consult the paper:

Modeling long-term uptake and re-volatilization of semi-volatile organic compounds (SVOCs) across the soil–atmosphere interface

Thank you Dr. Pudykiewicz for response, I will go through the paper

Dear Dr. Rajanna,

According to the recent research, still quite preliminary, we can speculate that the microbial population of the atmosphere can indeed contribute to the biodegradation of some chemicals. This statement is particularly true in the atmosphere with clouds

Considering the time scale of the residence of the pollutants in the atmosphere, the effectiveness of this pathway of biodegradation is much smaller than in other environmental compartments.

Yes Dr. Pudykiewicz, seems microbial degradation in the atmosphere is negligible, and the suspended pollutants might be coming to earth through various agents like precipitation.
