MPC

“MPC” is an abbreviation that is used in various fields of science and technology to indicate maximum permissible concentrations. These are concentrations of pollutants in air, water or soil that do not pose a threat to human health and life. But it can also have a negative impact on the environment, plants and animals.

MPC is measured in substances per unit volume. Substances can be chemical (oxides of sulfur, nitrogen, carbon, heavy metals, aldehydes, etc.), organic (benzene, toluene, xylene, etc.) or radioactive. At the same time, the maximum permissible concentration may differ for different levels of danger of a substance and environment (air, water, soil, etc.), as well as for different living organisms (human body, animal body, plants).

For each substance, its own maximum permissible concentration is established, and for each substance this concentration may depend on many factors, such as the type and age of the organism, living conditions, work in industry, etc. There are different levels of maximum permissible concentrations, such as the maximum single concentration; average daily; critical load on the population (pollution hazard index); and average concentration.

An example of measuring the MPC level can be air measurements, or taking water samples to determine the content of hazardous substances in it. To identify air pollution, systematic measurements of its composition are carried out in all points of the city. Analysis of water samples helps to determine the cause of deterioration in its quality and identify sources of pollution. Measuring the composition of drinking water helps identify the presence of harmful substances. Such control allows you to avoid the effects of harmful and toxic substances, reduce the risk of dangerous diseases, protect
