Photochemical Smog Help~ Ha.. You guys deserve it…

‘Smog’ is made up of two words, what are they?

Smog The word ‘smog’ comes from two words: smoke and fog. Characterize visible combination of smoke and fog

Photochemical smog is a mixture of pollutants, what are they?

Composition Nitrogen oxides Ozone Aldehydes Unreacted carbon Particular matter Peroxyaceyl nitrate (PAN)

Temperature Inversion

Formation

What colour is photochemical smog?

Colour Nitrogen dioxide is responsible for the brownish colour of the haze. The particulates formed and the brown colour of nitrogen dioxide give the air a dirty, ‘smoggy’ appearance.

What are the disadvantages of having photochemical smog? a. headaches b. eye, nose and throat irritation c. impaired lung function d. coughing and wheeling e. damaging plants

Effects Effects on human health Headaches Eyes, nose and throat irritations Impaired lung function Coughing and wheezing

Damage to materials Ozones causes rubber to deteriorate

Effects on the atmosphere Reduce visibility Toxicity to plants
