![]() The control and monitoring of the air quality must be carried out with air quality networks, a work in which ENVIRA IoT has a long career. Immission of air pollutants with monitoring networks Their CEMS are optimized to provide high reliability with little maintenance. The shelters are equipped with measurement instruments for the monitoring of parameters like:ĮNVIRA IoT has an extensive experience in the design, supply and installation of Continuous Emission Monitoring Systems. Continuous Emission Monitoring Systems (CEMS) are used to control emissions in industrial installations (cement plants, power plants, chemical plants, refineries, paper plants, etc.). How are emissions controlled?ĭifferent international organizations have developed reference guides and regulations that define the emission limits allowed for different types of sources. Immission is the concentration of pollutants at ground level that can affect people, animals, vegetation or materials. In summary, emissions are related to the output of polluting substances to the atmosphere from any source, while immission, on the other hand, constitutes what is known as “air quality”. However, the following table reflects the main distinctive aspects: The definitions and characterizations made for both concepts reveal in a clear way what their main differences are. Differences between emission and immission The atmosphere plays a key role in the immission, since a polluting substance, when it is emitted, undergoes a series of physical and chemical transformations in the air (transport and dispersion, for example) that cause that emission and immission do not have a direct relationship. A cap whose goal is to protect human health and preserve the environment.A value whose limit is established under scientific knowledge.An amount, measured in different units, of a polluting substance present at a given time.To these characteristics, it is convenient to add that their origin can be natural (unintentional forest fires, volcanic eruptions, etc.) or anthropogenic (vehicles, industries, etc.).Īlso, the term emission alludes to different media or ecosystems, but in the present article, only its condition to the atmosphere is taken into account. With the ability to affect the atmosphere, water or soil interchangeably.In the form of gas, liquid, solid or energy.Continuous or discontinuous (irregular).The term emission is included in different regulations and the emissions can be: Their mention in the normative field is quite common, but they do not mean the same and they do not even have to keep a direct relationship. When talking about air quality and air pollution, it is usual to refer to immission vs emission, two concepts that, sometimes, lead to error.
