The indicator of sanitary and toxicological compliance. It indicates the chemical composition and for this purpose an analysis of the concentration of a number of impurities is carried out. This study includes the following: those that enter as a result of pollution, as reagents during resource preparation, of natural origin. Specialists determine the presence of As, mercury, strontium, chromium. They can cause significant harm up to death. As a result, the presence of pesticides, petroleum products is determined. They can enter during accidents at facilities, discharge of waste liquid from agricultural complexes.
From the point of view of chemical criteria
A number of elements may be colombia phone number library in the liquid that can cause irreparable harm to health. These include the following.
salts of sulfuric, nitric and nitrous acids;
iron;
bromine;
boron;
iodine;
surfactants;
pesticides;
compounds of manganese, fluorine.
Sulfuric acid affects the work of the gastrointestinal tract. When exceeded, acidity begins to devops department of md audit llc and an upset occurs. The body begins to age if this indicator becomes 5 times greater.
Nitric and nitrous acids have their own unique property
When they enter the human body – they are reduced to nitrites. When interacting with hemoglobin, methemoglobin is formed, which is dangerous to health. It does not carry oxygen and leads to cell starvation.
If there is an excess of Fe, the liquid becomes yellowish and acquires a characteristic metallic taste. Such a sault data can provoke allergic reactions with the appearance of rashes, peeling and itching. If this happens repeatedly, a person may have kidney problems, the likelihood of a heart attack increases, and the reproductive system suffers. It is found in large quantities in surface or artesian water.
SanPiN requirements strictly regulate the amount of bromine. When the concentration increases, the functioning of the kidneys, heart, blood vessels, and nervous system is disrupted, and characteristic rashes may appear – bromoderma. Experts say the main reason for Br getting in is unauthorized discharge of wastewater by enterprises.
