Use gas powered stations, replacing coal powered. 

Limiting use of cars

Banning use of trucks and other heavy emission vehicles 

Reduce emmisions from factory

300
Give an example of a secondary pollutant.

- tropospheric ozone

400

Define secondary pollutants.

Formed when primary pollutants undergo reactions whilst already in the atmosphere.

State the main effects on humans, plants and materials and products.
plants: leaves absorb ozone; degrades chlorophyll; reduces photosynthesis

humans: breathing difficulties; respiratory diseases

materials and products: attacks rubber and some plastics; degrades car tires; bleaches fabrics
