Scientific report -Water, land and air analysis- This activity is a final product of the Virtual Eden project. Students from the four countries collected water, land and air samples and then they analysed them. So, we can see how clean our environment is.
Water Methods and materials: -w-water samples from various locations -m-making a map of the locations -m-macroscopic, microscopic and chemical analysis -d-decantation and filtration for residues -p-pH (pH-meter)
Kiskunhalas is situated in between two major rivers, the Danube and the Tisza. The town used to be surrounded by lakes, ponds, swamps, all rich in fish. WATER -Hungary- Sample 1 Sample 3 Sample 2 Minerals, plants and algae; water is kind of green 8 pH 8,5 pHSóstó Dongéri canal, where thermal water is let into the canal Dongéri canal, near the school
Jastrzębie-Zdrój is situated at the watershed of two drainage areas in Poland: the Vistula river and the Oder river. Within the Jastrzębie-Zdrój city limits eight streams have their sources. WATER -Poland-

Microscopic findings WATER -Czech Republic-
Water Romania The first sample of water was taken from The Dâmboviţa River, in Budeşti town. The second sample of water was taken from The Danube River, in Olteniţa town. The third sample of water was taken from the Red Lake, a natural lake in the mountains.
The Red Lake The water has nearly no odour. The water is transparent. 350mg/l of natural remains in the water. Almost 7 pH. The Danube river in Olteniţa town The water has a bad odour. It is almost matte. 900 mg/l of residues. 6,5pH. Dâmboviţa river in Budeşti town The water has a bad rotten odour. It is almost matte. 800 mg/l of residues. 6,3 pH. Water Romania
Air Methods and materials: -a-air samples from various locations -m-making a map of the locations -d-determination of samples odour -t-taking a photo of plants in surveyed area
Kiskunhalas is situated in the great plain of Hungary, called Alföld. The air pollution is moderate here. The main source of pollution is a main road, which goes across this area. In addition, in the winters we have to heat up our homes and we also generate some carbon dioxide, nitric oxide and loose soot with it. Air -Hungary- Plants aren't affected by air pollution. The leaves are nice green, with no significant discolorations.
Lichens are good indicators: if you can see lichens somewhere, the air has got very small amount of SO 2 there or it hasn’t got any at all. This means the air is not polluted. Air -Hungary- We have found a lot of lichens around our school.
Air pollution is one of the most dangerous environmental hazards. Air pollutants arise from a wide variety of sources, although they are mainly a result of the combustion process. Air -Poland- The map lichen can be seen in the survey area. It indicates low air pollution.
Sample 1 Sample 3 Sample 2 The outskirt of the surveyed area In the woods A small dust content A large dust content
Air -Czech Republic- Sample 1 Sample 2 The corner of a school building At the church, near the village park No dust or dirt Large pollution – dust and dirt Dub nad Moravou is a village far away from industrial centers.
Bucharest is the largest city of Romania, so it is the most polluted. The centre of Bucharest, where our school is situated, is the most polluted zone of the city. Air -Romania-
The schoolyard Outskirts of Bucharest Healthy green plants Trees with significant discoloration and a dust layer
Soil Methods and materials: -s-soil samples from various locations -m-making a map of the locations -m-macroscopic, microscopic and chemical analysis of soil samples -d-decantation and filtration -p-pH (pH-meter)
Soil -Hungary- In Kiskunhalas, students found mainly sandy soil with humus and lick soil. A soil sample Nearby fields Roots, leaves, microorganisms, residues, twigs. 8,8 pH
Soil -Poland- In the area of Jastrzębie-Zdrój two types of soil are predominant: Podzols and Cambisols.
In the surveyed area three illegal landfills were traced. Each of them extends on the area 3-4 m². They consist mainly of household waste and old tires. Soil -Poland- A soil sample In the forest 5,5 pH
The main agricultural crops grown in the zone of Dub nad Moravou area are potatoes, wheat, maize, sugar beet, oilseed rape and vegetables. The brown soil around the village is very fertile, with humus horizon about 30 cm high. Soil -Czech Republic- A soil sample A nearby field Small plant roots, remains of soil microorganisms, residues, leaves and twigs 5,7 pH
Soil Romania Bucharest is situated in the south eastern corner of the Romanian Plain, in an area once covered by the Vlăsiei forest, which, after it was cleared, gave way to a fertile flatland.
Three samples of soil were taken and analyzed. They contained roots, microorganisms, residues, particles of sand and broken pebbles. Illegal landfills were found near the school and in the center of Romana Square. Soil Romania

After analyzing the most important elements of our planet and, definitely, the indispensable things for our life, we found out that the Earth is in trouble. This trouble isn't big, provided that we care about it. We must think twice before doing something that might be harmful to the inhabitants of our planet. But if we don't care, it's going to be a disaster!
One of the most important activities of the Virtual Eden project is the analysis of water, air and soil, because we must know which are the problems of our environment to be able to fix them. Children in Kiskunhalas collected three samples of water: one from Sosto, and two from the Dongeri canal. In both cases, the water was a little basic. Jastrzębie-Zdrój is situated between the Oder and the Vistula and eight streams have their sources in the city. The two samples were collected from a pond and a spring. In both cases, the water was almost neutral. Students in the Czech Republic analysed two water samples from the Morava river and a garden lake. The water was almost neutral, which means very low pollution. These are microscopic findings in the analyzed water. In Romania, three water samples were collected. Two of them were taken from rivers in large towns and the third from a natural lake in the mountains. We found that the water from the rivers was largely polluted, but the one from the lake was clear. Hungarian students didn’t see high pollution in the air, as the plants weren't affected. There were also lots of lichens on the trees, which show the purity of the air. Lichens are very sensitive to toxic gas, like carbon dioxide, and when the air is polluted, they can't survive. Polish students also saw lichens on trees, so the air was not full of toxic gas. There were lots of dirt and dust on the samples from the outskirt of the surveyed area, but none on the ones from the forest. Lichens were also found in the Czech Republic, especially in the park, where the air is clean. But on the roads, there were lots of dirt and dust, made by the cars. Especially in the center of Bucharest, there’s always a heavy traffic, so the air is largely polluted. In the schoolyard, there was dust in the air. But in the outskirts of Bucharest, air was not polluted and plants were healthy. Children in Kiskunhalas found basic soil on the nearby fields. In Poland, the most common types of soil are Podzols and Cambisols Soil in the forest is not polluted, but we must avoid creating illegal landfills. In the Czech Republic, soil analyzed by the students wasn’t polluted, only containing ordinary natural remains. Students in Romania collected three soil samples, two from the area of the city, one from Moieciu town. They largely contained natural remains, not being very polluted. The most polluted sample was from the center of Bucharest and the less polluted – from Moieciu, a small town in the mountains. After analyzing water, air and soil we found out that we need to protect our planet in order to be able to live on it. If we don’t care the future will surely be a disaster.
