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.

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.

ACID RAINS
HERBERT BORMANN THE YALE AND DART MOUTH
ECOLOGIST WHO DISCORVED ACID RAINS IN 1971
![Page 22: Yamini](https://reader035.vdocument.in/reader035/viewer/2022070317/55656f4dd8b42a95028b4570/html5/thumbnails/22.jpg)
ACID RAINS IS CAUSED BECAUSE INCREASING LEVEL OF SULPHUR DIOXIDE AND NITROEN OXIDE IN THE AIR
![Page 23: Yamini](https://reader035.vdocument.in/reader035/viewer/2022070317/55656f4dd8b42a95028b4570/html5/thumbnails/23.jpg)
IN 1971 BORMANN DISOVERED THAT THE WATIER IN THE NEW HAMPSHIRE FOREST WHERE HE
WAS CONDUCTING HIS RESEARCH WAS FILLED WITH ACID RAINS

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

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
![Page 26: Yamini](https://reader035.vdocument.in/reader035/viewer/2022070317/55656f4dd8b42a95028b4570/html5/thumbnails/26.jpg)
ACID RAIN DEPOSIT IN THE FORM OF RAIN ,SNOW IN WET
CONDITIONS AND IN DRY CONDITIONS IN FORM OF
GASES AND PARTICLES.

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

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

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.

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
![Page 31: Yamini](https://reader035.vdocument.in/reader035/viewer/2022070317/55656f4dd8b42a95028b4570/html5/thumbnails/31.jpg)
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.
![Page 32: Yamini](https://reader035.vdocument.in/reader035/viewer/2022070317/55656f4dd8b42a95028b4570/html5/thumbnails/32.jpg)
AT THE same time, acid rain causes the
release of substances that are toxic to trees
and plants, such as aluminum, into the soil
