No; there is no place on earth without air pollution. The air has always been polluted to some extent. A pollutant is a contaminant that constrains performance in ecosystem functioning in one or more aspects. The atmosphere has always been polluted. However people contribute significantly to air pollution.
Somebody mentioned Texas, where I live. All of Texas receives slightly acidic rain; this means sulfates are present.
Volcanic activity has spread sulphates, chlorates and ash particulates. Smoke and carbon monoxide has been spread form natural fires. Radon gas, a result of earth's natural radiactive decay, is always seeping from the ground into the air; pine trees emit volatile organic compounds, animals emit methane, and dust , such as the Sahara desert, is spread from Afica to east North America.
And, I don't think I have to get into manmade pollutants.

Yes, very few. Only at a few high mountain peaks, but the pollution can be seen and it is rising.

Define "pollution"
Pollution is a natural occurence. The cosmos is dying.

On the surface no. Don't know how deep the oceans are affected.
