Conclusion.

WhAt Is AcId RaIN?Acid rain is rain that has been made by certain pollutants

in the air. It is formed when industries or factories burn any type of fuel and therefore they all produce lots of

different chemicals (especially nitrogen oxides and sulphur dioxide) which react with the tiny droplets of

water in clouds to form sulphuric and nitric acids. Acid rain could be a dry or wet deposition.

WhAt Is AcIdItY?

Acidity is measured using a pH scale. A pH scale

runs from zero (the most acidic) to 14 (the most

basic or alkaline). Something with a pH

value of 7, we call neutral, this means that it is neither acidic nor

alkaline. Acidity can be tested using

litmus paper. Acids turn litmus paper red, and alkalis turn it blue.

WhErE iS iT cOmInG fRoM? Scandinavia was the first place where acid rain was observed in 1950 and it was then that people began to realise that the origins of this pollution were far away in

Britain and Northern Europe.

WhAt iS aCiD rAiN cAuSeD bY?Human activities are the maincause of acid rain.Moreover, acid rain is mainlycaused by these substances: Carbon dioxide Carbon monoxide. Chlorofluorocarbons. Hazardous air pollutants

(HAPS). Lead. Nitrogen oxides. Ozone. Particulate matter (PM). Sulfur dioxides. Volatile organic

compounds (VOCs).Most of the pollutants are

from automobiles.

ThE eFfEcTs Of AcId RaIn.Forests.

Acid rain can effect trees in several different ways, it may:

dissolve the nutrients and minerals in the soil which help the trees to grow and be healthy.

cause trees to grow more slowly or even to die.

cause the release of harmful substances such as aluminium into the soil.

wear away the waxy protective coating of leaves, damaging them and preventing them from being able to photosynthesise properly.

Lakes and Rivers.

The water becomes clearer and the numbers of fish and other water animals decline.

Freshwater shrimps, snails, mussels are the most quickly affected by acidification followed by fish such as minnows, salmon and roach.

The acidity of the water can cause deformity in young fish and can prevent eggs from hatching properly.

The increase in acidity and aluminum levels can be deadly to aquatic wildlife.

Buildings.

The chemicals found in acid rain can cause paint to peel and stone statues to begin to appear old and worn down, which reduces their value and beauty

People.

Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases like asthma or chronic bronchitis.

Acid rain can cause respiratory problems, like pneumonia and bronchitis, and can even cause permanent lung damage like cancer.

Water we drink from taps can be contaminated by acid rain, which can damage the brain.

PoSsIbLe SoLuTiOnS

Government. Governments need to spend more money on pollution

control. Governments need to invest in researching different

ways to produce energy. Greater subsidies of public transport by the

government to encourage people to use public transport rather than always travelling by car.

To “wash” the coal to remove some of the sulfur.

You Understand the problem and its solutions. Turn off lights, computers, televisions, video games,

and other electrical equipment when you're not using them.

Encourage your parents to buy equipment that uses less electricity.

Install fluorescent light bulbs instead of incandescent light bulbs.

Try to reduce, reuse, and recycle as often as you can. When you are going to work, you could walk, ride your

bike, or take a bus.

CoNcLuSiOnS.

Acid rain is slowly deteriorating 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 should have filters so that less pollution goes

in the sky.
