Plants just dont show its reaction as in people it takes years to show signs of cancer that does not mean the damage is not being done. Ultraviolet light as seen in ozone generation bulbs which accurs under 200Nm although for production is produced at 185Nm works because this not natural spectrum adjusts the gravity of elements such as oxygen mutating its properties. Smell is carried in the air by organic microorganisms such as bacteria (mostly benefical) and virus's (mutant bacteria). Because the bacteria is such a simple form of life it dies much quicker do to changes of elements such as oxygen. It is radioactive and poisonous and since they can not breath it they quickly sufficate, then dehydrate, loose there water content, since solids are heavier then liquids they no longer float so to say, turn to dust and well disappear. People use ozone in their homes to clean the air so to say when they have allergies. Fine if no one who plans on breeding breaths it in but not the best solution. The people with allergies have allergies because they were not equipted with the means to handle the bacteria because they did not evolve with this symbiotic form of life or there means to deal with it was damaged some how. Things can be rebuilt with the right conditions and immunities can be obtained. The best way to combat these ailments is by taking calcium which kills virus's such as the calcium found in the olive tree as it is the most complex calcium so far publically found on earth. The calcium works as vaccines due by weakening the virus to a point where the body can learn have to break it down, as seen in the early and present vaccine technology since the days of cowpoxs back in Norway around 1801. I know this is a bit off topic but since ozone is a ultraviolet radioactive product I figured I would include it. (You should have seen the first one I typed up, God damn button mixups)
