The document discusses acid rain, which is primarily caused by human emissions of sulfur and nitrogen compounds that generate acids in the atmosphere, resulting in harmful effects on humans, plants, aquatic life, soil, and buildings. Acid rain has a pH between 3.5 and 5, significantly lower than the neutral pH of 7, leading to health issues, environmental degradation, and damage to infrastructure. The document emphasizes the need for pollution control measures and individual responsibility to protect the environment for future generations.
Acid rain
- 1. Prepared By: Awais Ahmad Teacher: Dr. M. Imran Class: ERS(4B)
- 2. Rain having mixture of sulphur, nitrogen & some organic Pollutants Mostly caused by human emissions of sulfur and nitrogen compounds which react in the atmosphere to produce acids (Sulphuric acid & nitric acid) Acid Rain
- 3. Formation Of Acid Rain
- 4. These acids increase the PH of atmospheric water Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are basic Distilled water, which contains no carbon dioxide, has a neutral pH of 7 Acid Rain
- 5. PH Scale
- 6. Clean or unpolluted rain is slightly acidic having pH of about 5.6 Acid rain has a PH ranges from 3.5 to 5 Acid Rain
- 7. Acid rain has a worse effect on: • Humans • Plants & vegetation • Aquatic life • Soil • Buildings Acid Rain
- 8. The sulphur dioxide and nitrogen gases, causes respiratory diseases like asthma, chronic bronchitis, etc. Effects On Human
- 9. Gastric disorder due to drinking acidic rain water Eyes and lungs inflammation Effects On Human
- 10. Acid rain dissolves all the nutrients and the useful minerals for the tree to grow Weakens the process of photosynthesis Effects On Plants
- 11. Acid rain increases the acidity of lakes & rivers, which is directly effect the aquatic ecosystem Species of fishes & invertebrate became extinct Effects On Aquatic Life
- 12. Effects the important ions exchange reaction in the soil Acidify the soil by removing essential nutrients like Al+3, K+1, Ca +2 Acids activate aluminium from the soil which leaches into water and fish die. Drinking water is contaminated Effect On Soil
- 13. Effect On Soil
- 14. The Tag Mahal in Agra, suffering from sulphuric acid, nitric acid & other fume pollutants Effect s On buildings
- 15. Acid rain cause extensive damage to statues, bridges & structural materials of marble and limestone, etc Effect On Statues
- 16. • Fit scrubbers into factory’s chimneys, which are chemical filters that remove impurities such as sulphur from smoke • Cars can be fitted whith special converters which remove dangerous chemicals • Goverments need to spend more money on pollution control Solution Of Acid Rain
- 17. Acid rain is slowly destroying our planet. It is our responsibility to make sure that we protect the earth for future generations to enjoy We should stop polluting, for example riding your car just to go to your neighbors five houses away from yours, or factories Conclusions
