Value for humanity Baikal is the largest freshwater lake on our planet. And, what is most beautiful, its waters have amazing purity (one of the cleanest lakes in the world). This natural wonder is located in Eastern Siberia (Russia). More than 300 rivers flow into the lake, but only one river flows out the Angara. But this river is very huge and has a length of 1779 kilometers. The hangar carries the clear waters of the lake over great distances, which is very healthy. Several large reservoirs have been creating on the river, which provides water to a huge number of people. The practical benefits of Lake Baikal are very great, but this is not the only advantage of the lake. Due to the content of large reserves of oxygen in all layers of water, a huge number of living organisms live in the reservoir. There are 2600 species of aquatic animals alone! Moreover, more than a thousand of them live only here. This fact makes the lake the property of the whole world, and these are not just beautiful words, but a fact. Lake Baikal is recognized as a World Natural Heritage Site. The preservation of the cleanliness of the reservoir is an important task to which Russia takes very seriously. A lot is being done to protect Baikal from pollution. But, as it usually happens, some people are not able to comprehend the value of the World Heritage property. This unflattering comment is addressed to Mongolia (East Asia) because it is on the territory of this country that the Selenga River is actively polluted, which subsequently flows into Lake Baikal. Origin and history Scientists estimate that Lake Baikal is about 25 million years old. The nature of its formation is still not established with accuracy, although most researchers are inclined to the tectonic origin. In any case, the age of Lake Baikal makes it a unique natural object, since usually, such lakes exist only for 10-15 thousand years. Although the opinion about the origin of the lake still raises a lot of questions, one thing is certain: the transformations in the area are continuing; regular earthquakes are observed, and the size of the lake increases annually by 2 centimeters. By the way, the size of Lake Baikal is impressive. Curved in the shape of a crescent, it reaches a length of 690 kilometers and a width of about 79. Lake Baikal takes 7th place in the world in terms of water surface, and its maximum depth reaches more than 1600 meters. Several tributaries constantly replenish the water reserve of the lake, and the most famous of them are the Barguzin and Verkhnyaya Angara, Turka and Snezhnaya rivers, and the largest tributary are the Selenga. The only Angara river takes its source from Baikal. The amazing lake was included in the UNESCO World Heritage List, and water, of course, was recognized as its main resource. It has a unique composition characterized by a low content of organic matter and minerals. The oxygen content is very high. The average water temperature does not reach above 10 degrees, but a maximum of 23 degrees is recorded in the bays. The water in Baikal is so clean and transparent that in some places visibility reaches 40 meters in depth. In a word, the lake is really difficult, and therefore the solution to the problem of its pollution is of such importance. Sources of danger The environmental problems of Lake Baikal were first announced in 1998, as part of a conference held by the Presidium of the Russian Academy of Sciences. A year later, in 1999, the federal law On the Protection of Lake Baikal was officially signed. This law spells out the requirements for a special regime for conducting business activities, as well as introduces basic prohibitions. All this was supposed to gradually solve the issue of pollution. A detailed approach to the problem, alas, is still quite difficult, since the unique biosphere of the lake has not yet been fully studied. Nevertheless, the main sources of pollution of Baikal’s waters have been identified with absolute accuracy: the polluted waters of the Selenga River and wastewater from Tourist camps, a series of hydroelectric power stations on the Angara River and the Baikal Pulp and Paper Mill. Selenga River, starting in Mongolia The pollution of Baikal has become a serious problem over the past 20 years. There are several reasons for environmental degradation. Among the main threats is the pollution of the waters of the Selenga River flowing into Baikal. It provides 50% of the water inflow entering the lake. Two-thirds of the area of the Selenga drainage basin is located in Mongolia. Wastes discharged by residents of the Mongolian capital Ulan Bator fall into the Selenga, and from there into Baikal. Erdenet, one of the main gold mining and copper beneficiation companies in Asia, and gold mines on the Tuul and Khara rivers also contribute. They are also located on the territory of Mongolia. Uncontrolled tourism There are many problems associated with uncontrolled tourism. “Tourism has become the most powerful factor in the pollution of nature on the coast of Lake Baikal,” says Dmitry Kobylkin, Minister of Natural Resources and Ecology. Over the past decade and a half, the flow of tourists has grown sharply. About 2.5 million people visit the Baikal coast annually. There are over a thousand hotels and campsites that do not always comply with environmental standards. The dumping of waste into the water, tons of garbage and countless buildings were the direct result of the tourist boom. Speaking about the pollution of Lake Baikal, you need to understand that we are not talking about the whole lake, but about coastal zones. Would the Chinese then buy unclean water? In the territory of Buryatia, there are not enough modern high-quality treatment facilities. This is especially true of the city of Ulan-Ude. Here it is necessary to accelerate the work on their modernization and look at local sources of pollution, starting with the fleet - these are two thousand vessels that need to be converted to gas engine fuel and ending with local treatment plants in villages that are located on the shore of Lake Baikal, the deputy noted in an interview with Tsargrad The State Duma is from Buryatia Nikolai Budget. Pulp and paper mill For about fifty years, the Baikal Pulp and Paper Mill (PPM) posed the main threat. Although the pulp and paper mill is already closed, the consequences of its activities are still affecting. Millions of tons of hazardous waste in sludge collectors leftover from the plant are located on the shore of Lake Baikal. These are areas with a high probability of earthquakes, floods, and mudflows. If due to natural disasters, the pulp and paper mill breaks through the pulp and paper mill, the release of dirt into the lake will be equal to discharges within 700 years, the Limnological Institute warns. Of the active sources of pollution, hydroelectric power plants on the Angara River should also be noted. A water bottling plant under construction in the coastal zone of Baikal (in Kultuk) for its export to China will also add to the ecosystem’s problems. However, the Irkutsk court upheld the decision on the illegality of the construction of this facility. In addition to the industrial impact, the damage to Lake Baikal is caused by guests and residents. The distribution of spirogyra, which Academician Fedotov spoke about, is associated with the dumping of waste along the coast where people live. The treatment facilities located here cannot cope with the treatment of wastewater to the required level. Many of them are worn out; there is not a sewage system everywhere. How we can to save Baikal? In April of this year, Minister of Natural Resources and Ecology Dmitry Kobylkin instructed the head of Rosleskhoz, Ivan Valentik, to develop a four-point action plan. Here they are: It is necessary to amend the federal law prohibiting the discharge of wastewater into Lake Baikal from industrial facilities and utilities. Prohibit the construction of non-environmental facilities in the coastal zone. Reduce pollution due to the Selenga River. Introduce the NDT Handbook “Wastewater Treatment”. These paragraphs almost exactly repeat the recommendations of international environmental organizations. But it is not yet clear at what stage the development of this plan is and when it will be implemented.
