This document discusses various types of environmental pollution including water pollution, soil pollution, noise pollution, and acid rain. It outlines the causes and effects of each type of pollution as well as potential measures to address them. Water pollution refers to contamination of water bodies caused by human activities and can harm aquatic plants and organisms. Soil pollution occurs when chemicals enter the soil and alter its natural environment. Noise pollution increases the risk of health issues like headaches and heart problems. Acid rain was discovered in 1971 and forms when emissions from vehicles and industry combine with water vapor in the atmosphere. It damages ecosystems and releases toxic chemicals like aluminum into water and soil.

9. Water pollution refers to the contamination of water bodies such
as rivers, oceans, lakes, and groundwater caused by human
activities. This can be harmful to plants and organisms which live
in these water bodies.

10. Causes of water pollution

11. Effects of water pollution

12. Measures of water pollution

13. Soil pollution is formed when man
made chemicals get into the soil and
change the natural soil environment.
Oil and fuel dumping, pesticides and
underground storage units are some of
the main culprits.

14. Causes of soil pollution

16. Measures of soil pollution

17. NOISE POLLUTION

18. Causes of sound pollution

19. Effects of sounds pollution
*Noise increases the
chances of occurrence of
diseases such as
headache, blood
pressure, heart failure, etc

20. Measures of sound pollution

21. ACID RAINS
HERBERT BORMANN THE YALE
AND DART MOUTH ECOLOGIST
WHO DISCORVED ACID RAINS IN
1971

22. ACID RAINS IS CAUSED BECAUSE INCREASING LEVEL OF
SULPHUR DIOXIDE AND NITROEN OXIDE IN THE AIR

23. IN 1971 BORMANN DISOVERED THAT THE
WATIER IN THE NEW HAMPSHIRE FOREST
WHERE HE WAS CONDUCTING HIS
RESEARCH WAS FILLED WITH ACID RAINS

24. MORE AMOUNT OF SULPHUR AND
NITROGEN RELEASED BY CARS AND
INDUSTRIAL PROCESSES .ACID RAINS IS
ALSO CALLED AS ACID DEPOSITION

25. HOW ACID RAIN FORMS
ACID RAIN FORMS WHEN WATER
VAPOUR AND CERTAIN ELEMENTS
COMBINE WITH MAN MADE
POLLUTANT SUCH AS NO IN THE
ATMOSPHERE FORMING SULPHUR
AND NITRIC ACID IN STATOSPHERE

26. ACID RAIN DEPOSIT IN THE FORM OF
RAIN ,SNOW IN WET CONDITIONS AND
IN DRY CONDITIONS IN FORM OF GASES
AND PARTICLES.

27. ACID RAIN AND DESTRUCTION ON CANADA
FOR THE LAST TEN YEARS ACID RAIN GOT
DESTRUCTION ON CANADA AND SOM E
PARTS OF EUROPE. IT IS THE MOST
COMMON PROBLEM IN EASTERN
CANADA BECAUSE OF LCK OF NATURAL
ALKINITY IN WATER AND SOIL SYSTEM

28. ACID RAINS FORMS WHEN OXIDES POF
NITROGEN AND SULPHUR COMBINE
WITH ATMOSPHERE. SOME OF ACID
RAIN ON HANDS

29. HOW ACID RAIN AFFECT ON FISHES
ACID RAIN FLOWS THROUGH WATER SHED
ALUMINIUM IS RELEASED FROM WATER
INTO LAKES AND STREAM LOCATED IN
WATER SHED.

30. PH OF LAKE DECREASES ALUMINIUM
LEVEL INCREASES .BOTH LOW PH AND
INCREASED ALUMINIUM ARE DIRECTLY
TOXIC TO FISHES. SO THEY BANNED
EATING FISHES IN SOME COUNTRIES
DUE TO ACID RAINS

31. ACID RAIN EFFECT ON PLANTS
acidic water dissolves the nutrients and helpful
minerals in the soil and then washes them away
before trees and other plants can use them to
grow.

32. AT THE same time, acid rain causes
the release of substances that are
toxic to trees and plants, such as
aluminum, into the soil
