Air pollution

  1. 1. Air pollutionTest of air pollution by lichens
  2. 2. Aim of work: To measure air pollution according to the pluralityand composition of lichens’ species.Hypothesis: The level of air pollution is bigger near the objectswhich pollute the environment greatly (roads, factories, housesetc.).
  3. 3. Test of air pollution by lichens: TypeResearched of Type of lichens Plenty Coverage, % SO₂ Zone place tree 1. Xanthoria parientina ++ 10 Vytautas Lime 2. Hypogymnia physodes ++ 10 To 70 3 street 3. Paramelia sulcata ++ 37 1. Xanthoria parientina ++ 9 Martišius Lime 2. Paramelia sulcata ++ 26 To 70 3 street 3.

  6. 6. Conclusions:1. We have found these lichens: . Xanthoria parientina, Hypogymnia physodes, Paramelia sulcata, Pseudevernia furfuracea.2. The degree of coverage fluctuates from 9% to 70%.3. The most polluted area was Statybininkai street, which means that it is the closest area to polluting objects. The least polluted area was Revuona’s park, which means that it is the furthest area from polluting objects as cars, industries and houses.4. Human beings are the ones who produce the most SO₂.
