Industrial smog differs from photochemical smog because ___.

• it comes from factories and not only combustion in motors

• it forms from smoke and sulfur dioxide emissions mixing with fog

• it is formed from PANs and VOCs

• it only forms in dry, sunny areas

NGSS.HS-ETS1-3

Which of the following in not true of the formation of photochemical smog?

• The main sources of volatile organic compounds (VOCs) industry, vehicles and solvents (e.g. used in paints and adhesives).

• The main sources of NOx are emissions from industry, power stations and vehicles.

• Forest fires reduce the levels of VOCs and particulate matter

• It occurs when sunlight activates reactions between nitrogen oxides (NOx) and volatile organic compounds (VOCs)

• The reactions result in the formation of ground level ozone and peroxyacyl nitrates (PAN).
