The causes of ozone

Ozone, the chemical formula is O3, also known as trioxygen, superoxygen, because of its similar fishy odor named, can be reduced to oxygen at room temperature. Larger than oxygen, slightly soluble in water, easy to decompose. Ozone by oxygen molecules carry an oxygen atom, so it is only a temporary state, carried oxygen atoms in addition to oxidation, the rest of the combined oxygen into a stable state, so there is no secondary pollution ozone. Ozone is mainly produced by nitrogen oxides (NOx) and volatile organic compounds (VOCs) through a series of complex photochemical reactions.
