Pollution of the Baltic Sea !

The main environmental problem in the Baltic Sea is its pollution. After the Second World War in the Baltic Sea were dropped about 3 million tons chemical weapons, which contained 14 highly toxic substances. At that time no one thought much about what consequences it may bring, and yet, even now, researchers have noted increased levels of these substances into the sea. And no one knows how many there will be ten - fifteen years ...The sea hides in its depths and radioactive substances. For a long time in the Baltic Sea through the Danish straits received radionuclides, which are dumped nuclear - processing plants in Western Europe. The accident at Chernobyl in 1986 greatly affected the radiation situation in the Baltic Sea. In the sea got a huge amount of radioactive substances (mainly cesium and strontium). Also in the depths of the Baltic Sea lies somewhat sunken nuclear submarines. All this has led to the fact that the fish caught in the Baltic Sea, the content of strontium and cesium to 5 times higher than normal.In the third part of the Baltic Sea at depths of 40-60 meters of oxygen in water is almost there, but almost everywhere there are toxic gases - hydrogen sulfide, nitrogen and phosphorus, in some places at the bottom of the Baltic Sea formed the so-called "death zone", the concentration of toxic substances in They are so great that there can not exist a single living organism.The situation is greatly exacerbated by the fact that the self-purification of water in the sea is very slow, as reported to the Baltic Sea to the North, just across the narrow Danish straits. For 70 years, the ecological situation on the sea very much worse, and while maintaining the same rate of contamination in 10 years, the water can not be used for food, and fauna of the risk of disappearing for ever .....
