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

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

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

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

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.

AT THE same time, acid rain causes the

release of substances that are toxic to trees

and plants, such as aluminum, into the soil
