BVT-Merkblatt zu Abwasser- und Abgasbehandlung

Annexes
The emission limit values contained in the TA Luft represent state-of-art for technical measures
for reducing emissions (dating from 1986). These values were developed referring to scientific
findings and research, taking into account toxicological, bioaccumulative and epidemiological
aspects.

Based on the decision adopted by the Conference of the Federal Government/Federal States Ministers for the Environment
on 21/22. November 1991, an emission concentration value of 0.1 mg/m³ has been stipulated for Cd and its
compounds, given as Cd, as well as for As and its compounds, given as As.
The required emission limits are given in mass of emitted substances related to the volume of emitted gas under standard
conditions (0°C, 101.3 kPa) after subtraction of the water vapour content.
If organic substances in several classes are present, the mass concentration in the emitted gas should not exceed a
total of 0.15 mg/Nm 3 with a total mass flow of 3 kg/h or more.
In the case of high emission mass flows, emissions have to be monitored continuously.
No daily mean value of the respective emitted substances should exceed the required emission
limits, 97 % of all half-hourly means should not exceed six fifths of the required emission limits,
and all half-hourly means should not exceed the required emission limits by more than
twice.
