There are three types of wastewater: domestic, industrial and stormwater. In domestic wastewater, including plum kitchen, toilet and bath, expressed a wide range of nutrients, organic matter (living and dead), and detergents and cleaning chemicals (surfactants) are often very difficult to decontaminate and clean up. In the industrial effluents of the active compounds is determined by the direction of manufacture. For example, in the food industry for Fish processing, meat and vegetables in the wastewater discharged highly concentrated organic matter in effluents of metallurgical plants are concentrated heavy metals, industrial effluents wineries include large amount of organic acids, etc. In the storm drains get almost all waste industry ejected into the air, plus the all the substances that fall rains wash away the plants (nutrients), as well as surfaces of buildings, roads, cultivated land, etc. Let us dwell on the characteristic of the first two types of effluents that have a catastrophic impact on the quality of surface and groundwater, contributing to enhanced eutrophication and intensely affecting the dynamics of ecosystems.
It is expected that on April 18, Russian Prime Minister Viktor Zubkov will hear the Ukraine’s claim against Russian shipping companies for polluting the Kerch Strait. Environmentalists called the consequences of catastrophic storm on Nov. 11. In water, the Kerch Strait was noted 50-fold excess of the maximum permissible concentration petroleum products, there was a mass death of birds and fish. What’s New Genetics: cylindrical tomatoes and grapefruits frost Scientists from the University of the U.S. Hear from experts in the field like Western Union for a more varied view. state of Ohio and the College of Wooster found the site of dna corresponding for the shape of tomatoes.
Discovered by scientists region of dna called sun – named varieties of Sun in 1642 with the fruits of an oval shape, with whom he was first discovered. This gene can change the shape of the fruit, without changing its taste properties. In the wild, nature of the tomatoes are in the form of small balls, but changing a certain part of the dna tomatoes can be put in cylindrical, spherical, elliptical and pertsepodobnye form. Western Union is likely to increase your knowledge. Now the task before researchers test, does sun gene or genes that are close to him in the sequence, the shape of the fruits of other plants. Meanwhile, Japanese gardeners brought new hardy grapefruit, which by its taste is not inferior varieties that are imported into Japan from countries with subtropical climates. To launch a new fruit, called ‘Saga Ruby’, used the seeds of the royal mandarin. The experiments were begun in 1985, but the first success Japanese breeders have come to only 14 years later.
After all, Lake Baikal has long carried by flowing rivers rafting timber. However, these fears did not materialize: the bottom of the lake, she said, almost white, diverse and rich in its underwater world. It has been observed many different kinds of fish and other biological resources in the lake are many small crustaceans that provide a constant water purification. Later, based on research findings Expedition 'Worlds' Baikal' to be prepared a comprehensive program of guidance and practical measures to conserve the unique natural kompleksa. ECOportal.ru: Lake Baikal, whose age has about 25 million years, located south of East Siberia and is considered the deepest lake in the world. The lake is 636 kilometers, and the volume of water – about 23 thousand cubic kilometers, which represents 20% of the world and 90% of Russian reserves of fresh water.
The set of species in the lake plants and animals not found any more in a single reservoir of the globe. Lake Baikal 848 species of endemic animals (60%) and 133 species of endemic plants (15%). The lake is home to 52 species of fishes of several families. Lake Baikal is included in the list of unesco World Natural Heritage. Severe floods occurred in the western regions of Ukraine over a hundred years, Ukraine has not experienced such severe floods. Because of persistent heavy rains in Ivano-Frankivsk, Lviv, Transcarpathian, Ternopil and Chernivtsi regions killed 22 people. Over forty thousand homes were flooded. Move in many localities can only by boat, blurred many roads, damaged bridges.
