Water pollution

In our time, the pollution of water is truly catastrophic. It is more difficult to get water of acceptable purity for drinking. Let's look at some of the most dangerous types of pollution.

Chemical contamination of water comes from both industrial enterprises and household waste, billions of tons of which are scattered all over the surface of not only land, but also oceans. Organic synthetic materials, for example, a variety of plastics, paints, polymeric fibers, washed away from the fields or discarded pesticides, which some agricultural large holdings like to abuse, means used for impregnating wooden structures and many other substances that are not capable of biological degradation , But they can be involved in the metabolism of living cells, acting there as catalysts of pathological metabolic processes.

And some chemicals that cause water pollution can be processed by living organisms, but often into compounds that are much more toxic to biological organisms than the original ones. Some of them are reliable carcinogens (substances that cause the formation of cancerous tumors), others have pronounced teratogenic and mutagenic properties (that is, cause congenital anomalies or mutations of biological organisms). Such an effect is inherent in halogenated hydrocarbons, polychromatic compounds and phenols.

Water pollution by nitrites and nitrates is most dangerous for children in the age group up to twelve years. In their stomachs, not yet produced enough acid to suppress those bacteria that process nitrates into more toxic nitrites. But this problem concerns not only children, such nitro compounds are formed under certain conditions even in the stomachs of adults and cause common poisoning. With this type of poisoning in newborns, the disease develops methhemoglobinaemia, called "blue baby syndrome", with this disease, the erythrocytes lose the ability to carry oxygen, the outcome of this pathology can be lethal.

Causes of developing cancer can become benzene and trichlorethylene and even asbestos. And if lead gets into the body, serious neurological pathologies may appear, especially children suffer from this.

Water and chlorine compounds are contaminated, which is actually used for its purification, but destroying microorganisms, it simultaneously saturates water with dangerous organochlorine compounds. From chlorine, water also gets an unpleasant taste and loses its transparency. And in the event that organochlorine compounds enter the body of a pregnant woman, they can cause severe congenital defects of the fetus, such as malformations of the heart and brain.

From manganese and iron, the water acquires a blackish or brownish hue, its taste deteriorates, the development of iron bacteria begins. Long-term use of such water contributes to the development of diseases of the blood, liver, the occurrence of heart attacks. Water contamination with oil also brings a whole range of complex organic substances to the water , which kill both human beings and the flora and fauna of reservoirs.

It's time for people to think about their actions, stop mocking the planet, because it can greatly reduce such a polluting factor as mankind, by one insignificant movement in the planetary scale, for example, the eruption of a large volcano or the emergence of a new virus. People need to love nature, and it will repay a hundredfold.
