Pyasino
Lake Pyasino (russian: Пясино) is a large freshwater lake in Krasnoyarsk Krai, north-central part of Russia. It is located at and has an area of 735 km². Many rivers empty into the lake, including the Ambarnaya. Water from the lake emerges as the river Pyasina. Pyasino freezes up in October and stays icebound until June. Environmental pollution As the recipient of polluted wastewater from Norilsk Nickel's metallurgical plants, it is almost completely devoid of fish. Environmental studies has been performed and comparative analysis of the data on heavy metal concentrations, namely Cu, Ni, Zn, Cd and Hg, in fish (burbot), moss, lichens, periphyton, hydric soils and snow in vicinity of Norilsk and further out in the most northern parts of the Taymyr Peninsula The Taymyr Peninsula (russian: Таймырский полуостров, Taymyrsky poluostrov) is a peninsula in the Far North of Russia, in the Siberian Federal District, that forms the northernmost part ...

Pyasina
The Pyasina (russian: Пясина) is a river in Krasnoyarsk Krai, Russia. The river is long, and its basin covers . The Pyasina River originates in Lake Pyasino and flows into the Pyasino Gulf of the Kara Sea. There are more than 60,000 lakes in the basin of the Pyasina covering a total area of . The river freezes up in late September or early October and stays under the ice until June. It is connected to the river Chetyrekh through its right distributary Staritsa. History The Dvina merchant Kondratiy Kurochkin reached the mouth of the Pyasina in 1610. In 1614, an ostrog was built on the river to collect yasak from the natives. In 1935, before the Dudinka-Norilsk railway had been built, the river Pyasina and Lake Pyasino were used to deliver cargo to the site of the future city of Norilsk.

Ambarnaya
The Ambarnaya (russian: Амбарная, translation=barn girl) is a river in Siberia which flows in a northerly direction into Lake Pyasino. On leaving Lake Pyasino, the waters emerge as the river Pyasina. It shares a common delta with the river Norilskaya. It is long, and has a drainage basin of . The river is fed by rain and meltwater. It is shallow and its bed consists of glacial moraine – gravel and pebbles. It is heavily polluted by the mining industry of Norilsk, namely Nornickel, so fishing is no longer possible. Diesel spill In May 2020, 20,000 tonnes of diesel fuel spilt into the river from a power plant. With a stretch of river seriously affected, Russia's president, Vladimir Putin Vladimir Vladimirovich Putin; (born 7 October 1952) is a Russian politician and former intelligence officer who holds the office of president of Russia.

Norilsk Oil Spill
The Norilsk diesel oil spill was an industrial disaster near Norilsk, Krasnoyarsk Krai, Russia. It began on 29 May 2020 when a fuel storage tank at Norilsk-Taimyr Energy's Thermal Power Plant No. 3 (owned by Nornickel) failed, flooding local rivers with up to 17,500 tonnes of diesel oil. President Vladimir Putin declared a state of emergency in early June. The incident has been described as the second-largest oil spill in modern Russian history, after the 1994 Komi pipeline spill, where 400,000 tonnes of crude oil were released to the environment between August 1994 and January 1995. Cause Diesel oil is used as a backup fuel for the Norilsk-Taimyr Energy coal-fired combined heat and power plant. Fuel storage Tank 5 failed due to holes at the tank bottom, caused by the formation of ulcerative corrosion. In 2014, the company had been ordered by the Russian regulatory agency for natural resources Rostekhnadzor to, by 2015, clean the outer surface of the walls and roof of the ta ...

Taymyr Peninsula
The Taymyr Peninsula (russian: Таймырский полуостров, Taymyrsky poluostrov) is a peninsula in the Far North of Russia, in the Siberian Federal District, that forms the northernmost part of the mainland of Eurasia.

Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydric Soil
Hydric soil is soil which is permanently or seasonally saturated by water, resulting in anaerobic conditions, as found in wetlands. Overview Most soils are aerobic. This is important because plant roots respire (that is, they consume oxygen and carbohydrates while releasing carbon dioxide) and there must be sufficient air—especially oxygen—in the soil to support most forms of soil life. Air normally moves through interconnected pores by forces such as changes in atmospheric pressure, the flushing action of rainwater, and by simple diffusion. In addition to plant roots, most forms of soil microorganisms need oxygen to survive. This is true of the more well-known soil animals as well, such as ants, earthworms and moles. But soils can often become saturated with water due to rainfall and flooding. Gas diffusion in soil slows (some 10,000 times slower) when soil becomes saturated with water because there are no open passageways for air to travel. When oxygen levels becom ...

Periphyton
Periphyton is a complex mixture of algae, cyanobacteria, heterotrophic microbes, and detritus that is attached to submerged surfaces in most aquatic ecosystems. The related term Aufwuchs (German "surface growth" or "overgrowth") refers to the collection of small animals and plants that adhere to open surfaces in aquatic environments, such as parts of rooted plants. Periphyton serves as an important food source for invertebrates, tadpoles, and some fish. It can also absorb contaminants, removing them from the water column and limiting their movement through the environment. The periphyton is also an important indicator of water quality; responses of this community to pollutants can be measured at a variety of scales representing physiological to community-level changes. Periphyton has often been used as an experimental system in, e.g., pollution-induced community tolerance studies. Composition In both marine and freshwater environments, algae – particularly green algae and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...
