General information about air quality

The quality of the air is crucial for the health and well-being of man and in order for nature to thrive. Maintaining air quality is one of the most important tasks of environmental protection, as the air is polluted by a variety of sources (transport, industry, agriculture, households and many others).

The operation of Munich Airport releases emissions. In addition to aircraft turbines, emissions are released by ground handling, the production of electricity, heating and cooling, aircraft maintenance, public and non-public road transport and many other activities. The main pollutants that may be released are nitrogen oxides NO2 and NO, particulate matter (PM₁₀ and PM_2,5) and various hydrocarbon compounds (including benzene and benzo(a)pyrene).

The requirements for air quality have become much more stringent since the airport was put into operation. The reason for this are European standards and transposing these into German law. In order to continuously monitor the influence of airport operations on air quality, Munich Airport therefore conducts extensive air pollution measurements in stationary and mobile monitoring stations.

The measurements are carried out by an accredited and notified monitoring point, in accordance with § 29b of the Federal Immission Control Act (BImSchG).

The air quality in accordance with the 39th BImSchV (Federal Immission Control Act)

The air quality is assessed in accordance with the 39th BImSchV by comparing measured air quality parameters (e.g. averages, maximum values, number of times the limit has been exceeded, dose) to the assessment values. The relevant limit and target values in the 39th BImSchV are shown in the table below.

Measurement parameters	Exposure limit according to 39th BImSchV
Sulphur dioxide (NO2)	40 µg/m³ (annual limit value) 200 µg/m³ (1h limit value when exceeding the limit on 18 permitted occasions)
Particulate matter PM10	40 µg/m³ (annual limit value) 50 µg/m³ (daily limit value when exceeding the limit on 35 permitted occasions)
Particulate matter PM2,5	25 µg/m³ (annual limit value)
Ozone (O3)	180 µg/m³ (1h average, information threshold) 120 µg/m³ (target value as the highest 8h average of a day value when exceeding the limit on 25 permitted occasions)
Carbon monoxide (CO)	10 mg/m³ (8h limit value)
Sulphur dioxide (SO2)	125 µg/m³ (daily limit value when exceeding the limit on 3 permitted occasions) 350 µg/m³ (1h limit value when exceeding the limit on 24 permitted occasions)
Benzene	5 µg/m³ (annual limit value)
Benzo(a)pyrene in PM10	1 ng/m³ (annual target value)

Thresholds for air quality according to TA Luft

In addition to the 39th BImSchV, the emissions concentration limits for so-called plant-related pollution control are regulated in the 'First General Administrative Procedure for the Federal Immission Control Act' (Technical Instructions for the Protection of Air - TA Luft). TA Luft is not, however, relevant as an administrative regulation. The exposure limit for dust precipitation under TA Luft is shown in the following table.

Measurement parameters	Pollution value according to TA Luft
Dust deposits	0,35 g/(m² x d) (for protection against serious nuisance)

Assessment values of the non-controlled measurement parameters for the air quality measurements

The evaluation values in the following table can be used for the parameters toluene, xylene, ethylbenzene and the n-alkane, which are not regulated in the 39th BImSchV.

Measurement parameters	Assessment value
Toluene Σ Xylenes Ethylbenzene Σ n-alkanes (C6-C14)	30 µg/m³ (target for the year, LAI) 30 µg/m³ (target for the year, LAI) Guide: 880 µg/m³ (1/100 OEL) 1) Alternative 1: 1/100 of the OEL 1) → Assessment values in the range mg/m³ Alternative 2: C9-C14 alkanes: 0,2 mg/m³ (guideline I) 2)

¹⁾ LAI 2004
²⁾ Indoor Air Committee, UBA. Guideline I (RW I) is the concentration of a substance in indoor air, in which, according to the present state of knowledge, no impairment of the health is to be expected in a single substance consideration if a person is exposed to this substance throughout his or her lifetime.


Good to know

The respective course of the air quality and weather data measurement values can be viewed under the 'Measurement parameters' menu item. This view can be selected by picking a day (e.g. 2 May 2016), taking into account the temporal resolution (hourly, eight-hour, daily and weekly averages). When selecting a month (without calendar day) or a year (without month), the respective monthly and annual averages can be displayed.

Global radiation is the entire solar radiation on the earth's surface impacting on a horizontal surface.
It is made up of
· the solar radiation impacting directly - direct solar radiation and
· of diffuse radiation, which is the radiation that reaches the earth's surface indirectly, scattered by clouds, water and dust particles.

The validated measurement data for all measurement parameters are made available in WebReporting. The subsequent requisite laboratory analyses, validations and evaluations of these measured data mean there is a time delay for retrieving the data. Depending on the parameter, the data are updated monthly or quarterly in WebReporting following validation.
