KATOWICE KATOWICE

AN INDUSTRIAL AN INDUSTRIAL DESERT OR A GREEN DESERT OR A GREEN

CITY?CITY?

3

Katowice is situated in the largest Polish industrial area – Upper Silesian Industry Area.

•capital city of the most urbanised agglomeration in the country

•one of the most heavily populated regions in Europe (4 million inhabitants).

•Katowice is perceived as an environmentally degraded area, simply an ecological desert.

•The data concerning the natural resources of the city contradict this view.

4

28% of the city area

is covered by forests

(the average forestation of

Poland is 28,7%)

RESEARCH ON SLEPIOTKA RIVER

carried out by students

6

What do we do?

We have inspected the condition

of contamination of water

from Slepiotka River.

Where do we research and what do we use?

•Every week we gauge the lower course of Slepiotka River near Park Zadole in Katowice–Ligota (in Śląska and Wczasowa Streets).

•For examining samples we use school equipment:

»Electrical pH meter (pH)»Electrical oxygenometer (O2)»Electrical thermometer (temperature)

8

The results are elaborated on in comparison

to the Polish standards of water purity classes, which are shown in the table

below.

Oxygen[mg/ l]

6 and more 5 and more 4 and more

9

The connection between oxygen dissolved in water and temperature is:

•the lower temperature the higher content of oxygen

(then the conditions for organism’s life in Slepiotka River are better).

10

•Comparing pH measurements we obtained average – 7,8 which means that the water is alkaline.

•Clear water should reach pH 7,0

•This slight difference means that water from Slepiotka isn’t clear, but enables animals and plants to live.

11

Water from Slepiotka River is

included to the III class of water

cleanliness because of high level of

contamination caused

by bringing waste into Slepiotka

River

by private owners.

OXYGEN

In winter months - the content of oxygen is higher than in the summer WHY? /MAYBE because of: the growth of rate of vegetation and the depth of the river.

The biggest difference in content of oxygen amounts is:- January: from 11,7mg/l (10.01) - May: 4,38mg/l (24.05),

16

The temperature of water depends on thetemperature of air, because the river is quite shallow – it reaches to 50 cm in depth..

The temperature is lower during the winter months.

The biggest differences in temperature is 15oC: from 19oC (in May) to 4oC (in December).

TEMPERATURE

17

pH of water is slightly alkaline and never turns sour.

- the lowest value is about 7,2 - the highest one about 8,2

WHY?It might be connected with:- the natural base on the bottom of the river - or with the wastes let in from private estates.

Rescue for Slepiotka River

Inhabitants of Katowice associate these rivers with stinking waste.

The analysed part of Slepiotka River is 27,2 km2 in area which makes 16,5% of Katowice area.

19

There is possibility to make it cleaner.

20

Slepiotka River has straight river-bed and concreted bottom.

If we raise the water level the nearby area

will be flowed giving about 1ha of clean

water.

21

THEN… - the water would not rush so fast through the river-bed BUT…- flowing calmly would give life to the plants (which are being destroyed now)

•the dominating species of trees and bushes,

•the degree of anthropogenic transformation

•the degree of the risk for the biodiversity coming from the alien invasive species.
