unfortunately, in our modern society is often seen as a favorite vacation spot, turned into a real dump of household garbage. So it is with lake Wojnowskie. We saw in the clear water just emerged from the winter ice of the lake, and various boxes, bottles, packaging from food and other debris. The lake shore is also full of various waste objects of human life, become unnecessary. the Parents and children come to feed the ducks and pigeons, throw out plastic bags of bread into the lake. Also in the winter time can be seen as a snowplow scraping the road with dirty snow, powdered reagents, dump it in the lake. The aim of our project is to identify the causes of the overgrowing of the lake Wojnowskie and attract the attention of citizens to the ecological problems of the lake with the aim of preserving the lake and surrounding areas clean.
throughout its existence was carried out consistent work to create and improve the conditions of their environment. The environment created by man, sometimes harmful for all living things: people, in an effort to create a good, to get them faster and cheaper, neglects, first, the interests of the environment. There comes a time when it appears that the air, water, soil is so poisoned that the person becomes impossible. Therefore, among the contemporary challenges facing the international community highlights the problem of deterioration of the external environment. And one of the environmental factors that have adverse effects on human health is the condition of the atmosphere.
Relevance: 2017 in Russia was the year of the environment. The purpose of this decision — to draw attention to problems in the environmental field, and to improve the status of ecological security of the country. You should pay special attention to the problem of air pollution. Many living organisms for normal functioning of the required atmospheric oxygen. We can't abandon it, so you need to think what to do to reduce air pollution.
the Existence of mankind is impossible without vital resources, one of which is water. Waters – is an essential element, without which it is impossible to imagine any landscape: Park and urban, suburban, and rural. And fresh water is the real wealth of our Land, which our planet is less and less.
very important, as early as possible to convey information about our reservoirs and save them from the contamination of domestic and agricultural waste.
the Decoration of our village is the river Urica. She source water for the population. I was wondering – is it safe to use water for domestic purposes, swimming and fishing?
the growing scale of production leads to an increase of anthropogenic impact on nature. Human impact leads to severe environmental pollution, and in particular to sink in the waters of untreated or inadequately treated sewage.
most of the districts of Murmansk region use for drinking water supply surface water sources (rivers and lakes), so in our region, there is an issue of treatment of industrial, agricultural, domestic sewage and clean drinking water sources themselves.
Drinking sources can be contaminated with various chemical elements, including nitrogen compounds. Nitrogen compounds are the components of sewage (ammonia and urea are waste products) and agricultural water (excess of fertilizers based on nitrogen washed into the groundwater). Their presence in water bodies causing mass development of plankton algae, the appearance of unpleasant tastes and odors of the water, disturbance of the oxygen regime (lack of oxygen), creates additional difficulties in the purification of water used for drinking and industrial purposes.
Object of study – waste water contaminated with nitrogen compounds modeled in the laboratory.
research Subject – efficiency of wastewater treatment from nitrogen compounds with Alga Chlorella vulgaris.
Hypothesis: Alga Chlorella vulgaris is able to effectively clean the waste water from nitrogen compounds under the conditions for active development.
Water plays in human life a huge role: they are used for drinking and domestic water use, sanitation, water transport, recreational purposes, etc. Integrated use of natural resources leads to their pollution and quality depletion.

- to Describe the geographical position of the lake.
2. To study the characteristics of hydrogeology and hydrography of the lake Small Vudyavr.
- to Compare the analyses of water in the lake Small Vudyavr in the period from may 2019 to November 2019. the
- to Analyse the results and draw conclusions.
Modern civilization depends on oil and products of its processing. Oil and its derivatives are used for the production of drugs, plastics, building materials, etc. every year the world produces about 500 million tons of oil. The place of production and the place of processing this mineral usually are far away from each other, refined oil need to be delivered to consumers around the world. Land transportation is mainly by pipeline and by sea — with the help of tankers. There are cases of accidents during transportation and production of hydrocarbons, in which the environment gets a huge number of “black gold”. A particularly strong negative impact on the environment have leakage of oil and oil products in marine ecosystems. Spillage of hydrocarbons at sea leads to pollution of the oil spill, the death of all life in this region and millions of losses. as example the accident in the Gulf of Mexico 10 years ago, when the explosion on an oil platform spilled 5 million barrels of black gold, and oil spill spread to 75 thousand km2. But most importantly - have suffered not only people, but also the fauna, some experts believe that it was the biggest man-made disaster that occurred due to the negligence of a person. Murmansk and Murmansk oblast are also at risk, because in the Kola Bay is a tanker , the Belokamenka”, a major oil terminal. In the region requires the monitoring of content of petroleum products in the waters of the Kola Bay.
the human Use of chemical substances in business activities and their involvement in the cycle of anthropogenic transformation in the environment is growing. From a large number of various chemical substances emitted into the environment from anthropogenic sources, special place is occupied by heavy metals (TM).
For the health of important value is the purity of used for drinking water. In this regard, the sanitary issue of supplying the population with quality water, i.e., having excellent organoleptic indicators (taste, odor, turbidity, color), no harmful chemical and microbiological composition, which deserves much attention.
This leads to the importance of monitoring water quality. Required sanitary supervision of the process of purification and disinfection of water in pipelines and the state of the water network.
Hypothesis: the quality of drinking water of Central water supply to the city of Snezhnogorsk of the Murmansk region corresponds to SanPiN 22.214.171.1244-01.
Objective: to Study whether air pollution by exhaust gases on the density of population of birds of the local area.
Hypothesis: air Pollution from exhaust gases has a detrimental effect on the density of population of birds
the Natural barrier of greenery (trees, shrubs) significantly reduce the level of airborne dust in the city.
the project develops a sense of community, hard work, responsibility, instills a love of nature, to the native land, for the country, and residents and guests of the city brings joy and aesthetic pleasure.
Almost every house has their favorite Pets. It's dogs, cats, fish, Guinea pigs, exotic animals.
Our yard is the planet of childhood, a place where we spend most of the time. And we do not care how it looks. Maintained daily seeing beautiful, always blossoming flower beds, we will not only get positive emotions but also learn to preserve the beauty, but will try to create her own hands.
Snow – one of the most informative and convenient indicators of environmental pollution. Harmful substances emitted by industrial enterprises, automobile exhausts,accumulate in the snow and melt water enter the soil, in the open and underground waters, contaminating them. If you take samples of snow in different places (in a Park, on the sidewalk, near the highway, in the yard, etc.), it is possible to make rather detailed picture of the degree of pollution of the environment, and to identify the cause and sources of pollution.
Hypothesis: externally clean and white snow really is – is dirty, it may cause harm to human health; the snow is more dirty in the most passable and passable areas of the city, near the boiler room.The snow is most pure in small and remote city, than in larger.
Since the mid-20th century due to increased human impact on nature (anthropogenic impact) the environment has acquired a special significance as a scientific basis for rational nature management and protection of living organisms.
today in the world's oceans each year falls :
- 30 million tons of petroleum products; the
- 50 thousand tons of DDT and pesticides; the
- 5 thousand tons of mercury; the
- 6 million tons of phosphorus; the
- 2 million tons of lead, etc.
In the oceans to find the point where it would be observed consequences of anthropogenic impact. Even in bone tissues of Antarctic penguins discovered traces of pesticides and heavy metals.
the Danger of anthropogenic air pollution is primarily determined by the slow processes of self-purification of the ocean, the rapid spread of contaminants and diversity of pollution sources.
the Main idea of this work is the importance of the world ocean for the entire globe and the whole person. It is important to remember the close relationship of all ecological systems, communities inside of ocean between themselves and a close connection of the oceans with the world of sushi, with our planet as a whole. Every living plant, every living thing, every inanimate object of the world ocean is a link of one of the closed circuit inside of it. The disappearance of even a seemingly the unimportant link in the chain can lead to irreversible consequences.
the Relevance of my chosen topic is that water is the source of all life on Earth. This research I wanted to expand my knowledge on the composition and property of water and to encourage people to ambition and care about the environment.
Aims and objectives of the study
the Purpose of my work is the study of some physico-chemical properties of water of the Barents sea in the Arctic area "Hot streams”.
Based on this goal, I set myself the following objectives:
1.To determine physico-chemical characteristics of water
- Analyze results
3.To offer solutions to environmental problems.
On the territory of the Kandalaksha district has a large number of springs, four of which are widely used by local population for water intake for drinking purposes. However, at the moment there is no systematic official data on the environmental status of the considered sources.
currently, there is a striking proliferation of mistletoe on the territory of Murmansk region. The most favorable conditions for the development of its populations are formed in localities where plantings are more attenuated than in vivo, due to the significant anthropogenic load.
Mushrooms are able to absorb harmful substances like a sponge. Especially dangerous in this case heavy metals. They can adversely affect plants, accumulate in the stems, leaves, and fruits of plants. the Impact of copper-Nickel plant on the environment of our city great. One of the factors of such influence is the presence of heavy metals in the soil. We decided to check out what heavy metals may be contained in soil in the vicinity and in the city of Zapolyarny.
many people throughout life had garden plots, cottages and objects. The owners of the site strive to grow healthy food. The state of the soil affects the health of children and adults. the Use of fertilizers and pesticides, the nearby highways and industrial facilities, illiterate management technique vegetable leads to toxic contamination of the soil, its depletion and, as a consequence, — to the denaturalization of crops.
the problem For the period 1996-2020 year there have been significant changes in human activities on the territory of the settlement mezhdurech'e - closed poultry farm, the construction of a transportation hub. How will this affect the ecosystem of the river Malaya Lavna?
