What is the method by which environmental health is determined?

This method is called the biological indication method. The essence of this method lies in the fact that specialists (usually representatives of the sanitary and epidemiological station are engaged in this) take samples of water, air, various biological samples, soil and other things in a specific area. This is done in several places. Next, the samples are analyzed using special methods using chemical reagents. So they can give a fairly accurate assessment of the environment in a certain area. Typically, these checks are done several times at different times of the year.
