Emission is the release of certain substances from a source into the atmosphere that, in certain concentrations, can be harmful to humans, plants and animals, as well as goods created naturally and by human activity. These substances are therefore called pollutants. Emissions can be divided into natural and anthropogenic emissions. Natural emissions occur through the emission of substances by living beings (respiration), decay, as well as from other natural processes (eolian erosion, forest fires). Anthropogenic emissions occur in: 1. Energy facilities - e.g. emissions resulting from the combustion of fuel for heating purposes; 2. Industrial plants - emissions resulting from technological processes; 3. Residential sector - emissions resulting from the combustion of fuel for heating, cooking, preparation of domestic hot water, etc. in households; and 4. Transport. Energy facilities include thermal power plants, heating plants, individual boiler rooms for the production of energy for heating and technological needs. The aim of the register is to present emissions, circumstances and activities that affect air emissions. The emissions register is made for the following air pollutants: sulfur dioxide, nitrous oxides, carbon dioxide, carbon monoxide, ammonia, nitrous oxides, methane, non-methane hydrocarbons, benzene and PM10.
