The powerful urbanization of recent years has led tothat humanity was on the verge of a real ecological disaster. There is a shortage of clean water and air, as well as food that is not contaminated by various kinds of harmful substances. Therefore, nature conservation, an important element of which is environmental monitoring, is becoming an increasingly priority area in almost all developed countries.
What is it?In simpler terms, such monitoring is a system of interconnected system measures, with the continuous implementation of which scientists receive information about the current state of specific ecological systems, and can also detect in time signs of violations beginning in a particular biocenosis.
Причем с каждым годом все большее значение It acquires not so much the classical monitoring of the environment, as its variety, which studies the influence of man on the environment. Such control is especially relevant in the vicinity of large cities, which have a disastrous impact on nature.
Не следует считать, будто все эти мероприятия represented by only two measurements. As already mentioned, environmental monitoring is a measurement system. Monitoring of the purity of the atmospheric air; scientists take samples of specific precipitation or snow cover; samples are also taken for analysis from water bodies.
It should be noted that environmental testing for air should be carried out daily where there is a developed industrial production.
It is especially important to determine whether there is airbornehazardous substances such as hydrogen sulfide, formaldehyde, sulfur dioxide and nitrogen dioxide. They can cause the fallout of the so-called acid precipitation, from which large cities constantly suffer.
Equally important is environmental monitoring,aimed at studying precipitation. Lead, cadmium, mercury and arsenic levels are measured in sediments near large industrial centers. Any excess of their maximum permissible concentrations can lead to serious health problems among the local population.
Accordingly, conducting soil analyzes near industrial cities is also important.
Such studies are conducted annually, while monitoring also determines the degree of soil contamination with heavy metals.
In the light of relatively recent events in Japan and in the Primorsky region, environmental monitoring associated with measurements of radiation activity has become extremely important.
Summing up, we can say that the prevention of situations dangerous for the environment depends largely on the correct and timely measurements that can warn of danger in time.
