AIR POLLUTION The presentation is made by Ksenia KiselevaСлайд 2
Air pollution occurs when gases, dust particles, or smoke are introduced into the atmosphere in a way that makes it harmful to humans, animals and plant . This is because the air becomes dirty or unclean. WHAT IS AIR POLLUTION?
Слайд 3
WHAT CAUSES AIR POLLUTION? Air pollution can result from both human and natural actions. Natural events that pollute the air include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds and natural radioactivity. Pollution from natural occurrences are not very often.
Слайд 4
HUMAN ACTIVITIES THAT RESULT IN AIR POLLUTION INCLUDE: Emissions from industries
Слайд 5
HUMAN ACTIVITIES THAT RESULT IN AIR POLLUTION INCLUDE: Burning fossil fuels
Слайд 6

Слайд 9
WHAT ARE THE EFFECTS OF AIR POLLUTION?
Слайд 10
CHEMICAL REACTIONS INVOLVING AIR POLLUTANTS CAN CREATE ACIDIC COMPOUNDS WHICH CAN CAUSE HARM TO BUILDINGS.
Слайд 11
Air pollutants can be in the form of particulate matter which can be very harmful to our health. The level of effect usually depends on the length of time of exposure, as well the kind and concentration of chemicals and particles exposed to.
Слайд 12
Short-term effects include irritation to the eyes, nose and throat, headaches, nausea, and allergic reactions. Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves.
Слайд 13
PREVENTION INTERVENTIONS IS ALWAYS A BETTER WAY OF CONTROLLING AIR POLLUTION. The first solution is that we should use energy (light, water, boiler, kettle and fire woods) wisely. This is because lots of fossil fuels are burned to generate electricity, and so if we can cut down the use, we will also cut down the amount of pollution we create.
Слайд 14
AIR POLLUTION PREVENTION & SOLUTION Encourage your family to use the bus, train or bike when commuting. If we all do this, there will be less cars on road and less fumes.
