    Can someone explain to me why ozone is bad to breathe? I understand what it does but I'd like to know why.

    Also, what affects the level of ground level ozone? I was watching a map and the levels changed a lot faster than I would have expected. I know that storms create ozone (does anyone know how?) and pollution (when NOx and VOC react with eachother...or something) but can that change the levels the way it does on this map?

    And is it bad that I'm asking a question here? I feel like I shouldn't be but I don't know where else to post this.

    Ozone is a highly reactive oxidizer and reacts with plant and animal tissue. Beyond that I don't know much detail on bad stuff it is supposed to do. BTW, it does some good stuff like disinfectant.

    You have the general idea on the production on ground-level ozone. However the chemical reaction(s) chain requires sunlight. Ground level ozone only appears during the day. It does vary quite a bit because of its fast reactions it doesn't last long. E.g. about an hour after sundown, it's all gone.

    ozone is more an irritant than toxic. at ground level or in the lower atmosphere very little exist. industry, cars and produce some and unless a static air condition exist, you would never know its there.

    oxygen is transformed to ozone, by electrical shock or as some say is cooked from heat. in the upper atmosphere, where most ozone is the thunder storms do create most of this element. cloud to cloud lightning being the most effective.

    ozone, retards ultra violate rays from reaching the earth. this is a good thing as these rays are harmful to plants and mankind. so its somewhat bad when trapped over a city and a good thing when in the 2nd layer of atmosphere.

    there is some misunderstanding from the phrase "ozone layer", as no such layer exist. ozone is scattered and in very low quantities compared to all other elements in our air...
