Belgorod oblast belongs to the shallow regions of ROSSion. Only about 1% of the territory is occupied by surface water: rivers, lakes, swamps, reservoirs and ponds. On the territory of the region is 480 rivers and streams.
In General, relatively low water availability of the region's territory is aggravated by the silting up of small rivers, the violation of groundwater, forthe pollution of water bodies. Therefore, the water-ecological problems are to Belgorudskoi region is much more acute than atmospheric.
Special attention should be paid to small rivers, which include reka Black Kalitva, originating and flowing through the territory onSzego and neighboring villages and springs feeding the river. Therefore, the monitoring of their ecological status is relevant topic.
At the beginning of the design work was put forward hypothesis: the ecological status of surface waters of Red village Alekseevsky district is not satisfactory.
Water - the cradle of life. Without water life on Earth would not even appear. Without it, there would be no plants, no animals. There would be no us. Water is used everywhere: in agriculture, in industry, in everyday life. Water is amazing for its properties. And these properties we will discuss.
For the normal functioning of the body needs water, does not contain harmful impurities and additives mechanical, i.e. good quality. And we wondered what kind of water we drink? How to determine the quality of water in the school laboratory? Nowadays there are problems with quality drinking water.
Goal: a study of drinking water quality.
To achieve this goal, we identified the following tasks:the
- to Study the literature on the research topic; the
- to emphasize the importance of water for living organisms. the
- to develop a method for determining the quality of drinking water in the school lab; the
- to draw conclusions;
Hypothesis: Water from the tap is suitable for drinking
Landscaping and comprehensive study of a spring in the village of Krasnaya Prokhorovka district.
a Negative impact on the environment okazvaetsya pollution of air, soil, vegetation,deposition precipitation, sewage, and other, all this inevitably will manifest as changes in the quality of surface waters, particularly in small and medium-sized rivers. And it is near these rivers has a significant part of the population.
For our project we opted for the river Userdel Krasnogvardeisky district, because all along the river are many settlements. Constant contact with zagryaznenii waters will not lead to anything good and will only bring damage. Thus our task is to test the quality of water in the river Userdel to offer solutions to the problems on preservation of the rivers.
