Urban Microclimates and Pollution

 

 

 

 

Photochemical Smog Photochemical smog forms when volatile organic compounds and nitrogen oxides react with sunlight to form smog containing ozone, liquid particulates and other pollutants (e.g. the brown haze of nitrogen dioxide). PM10s are very small particles both naturally occurring (pollen) and man-made (e.g. from car exhaust fumes). They greatly contribute towards smog formation. Smog can cause great discomfort (especially for those suffering from asthma or bronchial disorders) and even death. Cities such as LA with high car usage (5 million cars burning 40 million litres of petrol a day) are very susceptible to photochemical smog. The clear, calm, high pressure conditions frequently experienced in LA are also ideal for smog formation
