I don't know what to say about this subject, not having been subjected to it (and also having a lawn and sometimes considering getting a (battery-powered) blower). I found this part of the article annoying in a misleading bad-sciency kind of way, though: The rest is emitted as toxic fumes of nitrogen oxides and volatile organic compounds (VOCs), two of the main ingredients in ground-level ozone, which both trigger asthma attacks and contribute to premature death. I know ground-level ozone is bad news, but it's still just O3 so there is no way any organic compounds are ingredients in it. Perhaps they play a part in the formation of ozone (I'm no chemist) but then say that. I had to look it up, and the US Environmental Protection Agency says [1]: [Ground-level ozone] is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC). This happens when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources chemically react in the presence of sunlight. So that sounds about right then, and was a very quick search away.
