What are the main characteristics of urban areas with high levels of photochemical smog?

• Large, open flat plains with frequent high winds

• High winds, wet weather, cloudy, many industries and vehicles

• Located in a basin or surrounded by mountains

• Located in a basin or surrounded by mountains, calm winds, dry weather, sunny, many industries and vehicles

A principal component of smog
Source: Chemical reaction catalyzed by SUNLIGHT that splits apart NO2 to eventually form this molecule
Health effects: breathing problems, reduced lung capacity, asthma, eye irritation, reduced resistance to disease
Environmental effects: can damage plants!
