Air Pollution's Impact on organisms and Its Control

Question

State how air pollutants affect organisms hence state how air pollution should be controlled.

Answer

Effects on organism

- Sulphur dioxide/nitrogen dioxide/dust/smoke/carbon iv oxide and agricultural sprays cause respiratory diseases and irritate respiratory systems
- Nitrogen dioxide /sulphur dioxide combine with atmospheric moisture to form acidic rainfall which is corrosive, poison plants, lower metabolic activities/photosynthesis; acidic soils destroy vegetation.
- Dust/ smoke reduce amount of light reaching on the plant lowering photosynthesis
- Carbon II oxide is a respiratory poison/combine with haemoglobin reducing oxygen carrying capacity of red blood cells
- Carbon iv oxide causes greenhouse effect by forming a layer around the earth's atmosphere/insulate the earth causing global warming/ change of climatic patterns
- Radioactive radiation causes mutation and cancer


Control methods

- Erect factories and power generating station from residential areas
- Build factories with chimneys to discharge waste gases up the ground
- Educate people on dangers of air pollution
- Filtration of waste gases to remove poisonous pollutants before being discharged into the air
- Use of alternative less polluting fuels like hydroelectric power/lead free fuels
- Use smokeless fuels in houses and factories
- Banning manufacture and use of chemical weapons
- Impose heavy fines on air polluters; (like factories)
