Smog is from large amounts of coal burning in an area, and is a mixture of smoke and sulphur dioxide. Now, we have photochemical smog, a mixture of nitrogen oxides, tropospheric ozone, aldehydes, volatile organic compounds (VOCs), and peroxyacyl nitrates (PAN). Smog is caused by a reaction between sunlight and emissions mainly from human activity. Photochemical smog is the chemical reaction of sunlight, nitrogen oxides (NOx) and volatile organic compounds (VOC's) in the atmosphere, which leaves airborne particles (called particulate matter) and ground-level ozone.

Chelsea has the reactions creating smog right, its down to the burning of fossil fuels. Health problems are caused due to the being high levels of carbon soot, and other toxic compounds within the smog (I.e. Sulphur dioxide), these are damaging to your lungs and can also be carcinogenic (causes cancer).

The above answer is very good. Smog is also largely comprised of ozone.
