The water needs of human body
• We can live for 1 or 2 weeks without food, but without water we can only 2 or 3 days.
• About the human body’s 80% is water.• We should drink averagely 2.5-3 litres of
water daily.

The main tasks of water in the organism
• Carries the nutrients to the cells.• Removes the roughage that being
producted through biol metabolism.• Makes the joints elastic.• Maintains the proton and electron levels.• Creates a flexible protecting shell for our
organs.

The humans daily water needs
• 2-3 litre clean drinking water.

What do the pupils drink?• Tea
• Soft drinks• Sugared juice• Energy drink
• These just deprive our body of more water, these are dehidrateing.

Do we thirst?• On Earth more than 1 billion people can’t get
clean drinking water.• In more than 2 billion people’s surroundings
the sewage disposal doesn’t solved.

What is the situation in Hungary?
• We use the 70% of fresh water to hosing.• The 40% of the water usage of the cities are
waste.• 612 m3 fresh water used per capita yearly.• Hingary is on the water shortaged countries’
list since 1992.• The country can become half arid to 2050.

The water-base of Kállósemjén
• A long time ago the area of Hungary was covered by the Paratethys ocean.
• This’ sediment banked up the Kárpát-basin.• The contaminating materials left behind from
the sediment still can be found in the water-base of our village.
• The toxic materials are filtrated by dry-cleaner devices.

The contaminating materials in our drinking water without filtrate
• Iron: maximum value: 0,2mg/l– in our village: 0,5mg/l
• Arsenic: maximum value : 0,01mg/l– in our village : 0,056mg/l
• Manganese: maximum value : 0,05 mg/l– in our village : 0,5mg/l
• Ammonia: maximum value : 0,5 mg/l– in our village : 1 mg/l

Past-present-future• A long time ago people used to pull up fresh water
from digged wells.
• Nowadays piped drinking water flows in most of the households and they drink mineral water.
• What is the future??? • Water in a plastic bag???? • It depends on you too!

What can you do?• Use water sparingly!• Turn the dripping tap off!• Shower intead of bath!• Turn the tap off meanwhile toothbrushing, or
dishwashing!• Use economical devices (wc tank, washing-
machine, dish-washer etc.)!• Use less chemicals!• Collect the rain for hosing in a house with a garden.

What can the smallholders do?
• Develop adequate irrigation system!• Reduce the use of artificial fertilizer!• Reduce the us of crop protection chemicals!• Don’t get hazardous waste into the earth or
dronking water!
![Page 17: The Life-giving Water Created by: Krisztina Tímea Egri.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649ce35503460f949ae5ea/html5/thumbnails/17.jpg)
Drug residues• The sewage farms cannot filter out drug
residues.• Hormone products that get into the water can
change the creatures gender.

Industrial pollute• The farmaceutical factories, hospitals and other
chemical plants let their sewage into the rivers.• 20 different antophlogistics were revealed in
natural waters.• The 55% of the sewage flows into the Duna
without cleaning.

Diseases caused by water contamination
• Kidney diseases• Brain dysfunction• Mental disorders
![Page 20: The Life-giving Water Created by: Krisztina Tímea Egri.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649ce35503460f949ae5ea/html5/thumbnails/20.jpg)
Beleive your eyes!• Make the following experiment and you too
can experience that what kind of damages the contaminating materials that get into the water can cause!
• Ask your parents for help to make these experiments. Only use the dangerous chemicals with the help of your parents!!!

The deatils of the experiment
Materials need for the experiment:• Fried suflower oil• Detergent• Benzine• Motor oil• Running water• Garden cress seeds• Glass jars for germination
![Page 22: The Life-giving Water Created by: Krisztina Tímea Egri.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649ce35503460f949ae5ea/html5/thumbnails/22.jpg)
The process of the experiment• Put a blotting paper on the bottom of every
glass jars and dabble • Strew on it 50 pieces of cress seeds• Drip in the first jar motor oil every two days• Fried sunflower oil on the second• Dishwater on the third• Benzine on the fourth• Clean running water on the fifth
![Page 23: The Life-giving Water Created by: Krisztina Tímea Egri.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649ce35503460f949ae5ea/html5/thumbnails/23.jpg)
Examine, how many seeds will germ in the different jars
Draw a conclusion!
