Nowadays, water pollution takes on a truly catastrophic proportions.All the more difficult to obtain drinking water of acceptable purity.Let's look at some of the most dangerous types of pollution.
Chemical contamination of the water comes from both industrial and household waste, billions of tons of which are scattered across the surface, not only the land, but the oceans.Organic synthetic materials, for example, a variety of plastics, paints, polymer fibers eroded from fields or thrown out of the incompetence of pesticides that are so fond of abuse, some large agricultural holdings, funds used for impregnation of wooden constructions and many other substances that are not capable of biodegradation, but may include in the metabolism of living cells, acting there as catalysts of pathological metabolic processes.
Some chemicals are causing pollution of water, can be processed by living organisms, but often such compounds, which are much more toxic to the biological organisms than the original.Some of them are true carcinogens (substances that cause cancer), others have pronounced teratogenic and mutagenic (ie, cause congenital birth defects or mutations of biological organisms).Such effects inherent halogenated hydrocarbons polychromatic compounds and phenols.
pollution of water by nitrates and nitrites is most dangerous for children in the age group up to twelve years.Their stomachs are not produced yet sufficient acid to suppress those bacteria which convert nitrates into more toxic nitrite.But this problem is not only children, such nitro compounds are formed under certain conditions, even in the stomachs of adult humans and cause systemic poisoning.When this kind of poisoning in newborn infants develop disease methemoglobinemia, called "blue baby syndrome", in this disease the red blood cells lose their ability to carry oxygen, the outcome of this disease can be fatal.
The causes of cancer may become, benzene and trichlorethylene, and even asbestos.And in contact with lead in the body can appear serious neurological diseases, especially children suffer.
soiled water and chlorine compounds, which generally is used to clean it, but destroying microorganisms, it simultaneously enriches the water dangerous organochlorine compounds.From chlorine water also acquires an unpleasant taste, and loses its transparency.And in the case where the organochlorine compounds to enter the body of the pregnant woman, which can cause severe birth defects of the fetus, such as malformations of the heart and brain.
from manganese and iron water becomes blackish or brownish shades, its taste deteriorates, begins the development of iron.Long-term use of such water contributes to the development of blood diseases, liver, heart attacks.Water pollution by oil in the water also brings a whole set of complex organic substances, deadly effects on both humans and the flora and fauna reservoirs.
People's time to reflect on their actions, cease to mock the planet, since it can greatly reduce the polluting factors such as humanity, a slight movement on a global scale, such as a volcanic eruption or a large emergence of a new virus.People need to love nature, and it will repay hundredfold.
