Immission measurement

from Wikipedia, the free encyclopedia

As emission measurement is used to measure is of emissions referred. It is used to gain knowledge about the emissions affecting protected goods such as people, animals and plants .

The operation of mobile and stationary systems is usually associated with emissions. In addition to air pollution, this also includes vibrations , noise , light and rays . To assess the impact of these emissions on objects to be protected, measurements are carried out in order to make quantitative statements, e.g. B. to be able to meet air or radiation exposure at a selected location. With data from immission measurements that were obtained in the vicinity of industrial plants, their diffuse emissions in particular can be recorded. This can be done using the source term back calculation . In terms of air pollution control, in accordance with Annex III of Directive 2008/50 / EC on air quality and clean air for Europe, immission measurements must be carried out where the highest concentrations of air pollutants are to be expected.

Depending on the measurement task and measurement method, the duration of the sampling for immission measurement can vary between a few minutes and several weeks. Both actively collecting systems and passive collectors can be used to measure the immission of fluids . The measurement methods can be enriching or non-enriching.

Measurands

Measured variables can be:

If the measured variables are time-dependent, for example on the daily or annual cycle , the measurement effort can be limited in time. Time dependencies can also be used to specifically measure maximum values.
