Effects of Air Pollution and the details.pptx

People will get to know about it

1. Effects of Air Pollution Harming Human Health Harming Animals and Plants Causing Acid Rain Reducing Sunlight Making a Hole in the Ozone Layer Adding Too Much Nitrogen to the Land Effects of Greenhouse Gas Pollution

2. Now we will discuss a little bit about 2 most serious issuses which are acid rain and ozone depletion (do not add in the main slide)

3. what is ozone layer The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation.  

4. what gases affect the ozone layer CFCs , halon , CCl 4 , CH 3 CCl 3 , HBFCs , HCFCs , CH 3 Br , CH 2 BrCl

5. Ozone Depletion. What is ozone layer depletion? How does it occur? The thinning of the ozone layer present in the upper atmosphere is called ozone layer depletion . Some chemical compounds release chlorine and bromine, which in exposure to high ultraviolet light causes the depletion of ozone.

6. Why can't we repair the ozone layer? If we could patch the hole over Antarctica, the natural ozone-oxygen cycle might fall back into balance. But unfortunately, we can't make more ozone to patch the hole. It takes a lot of energy to make ozone  

7. What is Acid Rain? Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms . Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. Acid rain comes in many forms: rain, snow, sleet, hail, and fog (wet deposition

8. What is the main cause of acid rain? Acid rain can be formed by natural causes, such as volcanic eruptions. More commonly. Burning fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles all release sulfur and nitrogen oxides into the atmosphere. And they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

9. Effects statues, buildings, and other manmade structures, and damage their surfaces. Water becomes more acidic to crayfish, clams, fish, and other aquatic animals. Acid rain also causes aluminum to be released into the soil, which makes it difficult for trees to take up water. sulfur dioxide and nitrogen oxides can cause respiratory diseases like asthma or chronic bronchitis and also affects the skin can cause rashes.

10. How to control acid rain switching from fossil fuels to renewable energy sources. using filtration systems in the engine to lower the emissions of sulfur dioxide and nitrogen oxide . Filter and detoxify the water used by the factories before returning it to the rivers and so on.  

11. Using public transports . Turn off the lights when not in use . Recycle and Reuse No to plastic bags . Reduction of forest fires and smoking 6. Use of fans instead of Air Conditioner . 7. Use filters for chimneys . 8. Avoid usage of crackers . 9. Avoid using of products with chemicals . 10. Implement Afforestation .

12. How to prevent traffic related air pollution
