The German Federal Environment Agency (UBA) and the Physikalisch-Technische Bundesanstalt (PTB), Germany´s National Metrology Institute, have been working together for more than 20 years to ensure the metrological traceability of ground-level ozone...

The Association for the Control of Emissions in Products for Flooring Installation, Adhesives and Building Materials (GEV) organised a round-robin test in 2023 with the purpose to update its list of recommended testing laboratories based on test...

The classification of asbestos containing materials (ACM) in „weakly bound“ and „strongly bound“, accord- ing to their density, does not allow for an unambiguous assessment of the potential risks that these materials pose. The evaluation of...

The German Committee on Hazardous Substances (AGS) has adopted the revised version of the Technical Rule for Hazardous Substances (TRGS) 402 “Identification and assessment of the risks from activities involving hazardous substances: inhalation...

Metal active gas and metal inert gas welding are associated with health risks from inhalable hazardous substances. Individual exposure is determined by relevant bound- ary conditions at the workplace. Here, results of exposure measurements on...

The object of the PCBMinTech research project was to minimize or prevent emissions of organic pollutants generated in silicone-processing plants during the production of silicone-containing products, in particular making use of a chlorine-containing...

In addition to the inhalation hazard and the hazard to the skin from particulate dusts and fibres at work-places, these can also trigger so-called mechanical-irritative effects (e. g. itching, coughing and sneezing, irritation of the skin and mucous...

Plasma processes (NTP) such as photooxidation have established themselves on the market for exhaust air purification. In particular, the combination of a wide variety of partial purification steps now means that a large number of emission reduction...

Volatile organic compounds (VOCs), especially terpenes form photooxidants like ozone. This way they harm the respiratory system of humans and reduce the growth of plants. As a result, the emission of VOCs in Germany are being restricted to about one...

This contribution provides an insight into the current course „Air Quality Modelling“ of the Master‘s course Environmental Engineering at the Ruhr-Universität Bochum. In addition to a brief introduction to the didactic concept, the various...

The massive decline of air traffic in consequence of the Covid-19 pandemic allowed a detailed analysis of aviation induced noise and particularly air pollution caused by kerosene combustion. As expected, aircraft noise is reduced significantly...

The method of polarity profiles is used to determine pleasant definitely facility odours and is prescribed as a method for the hedonic classification of facility odours in Annex 7 of the Technical Instructions on Air Quality Control (TA Luft 2021)....

The German Weather Service (Deutscher Wetterdienst) has published a report which describes methods for determining the effective roughness length from wind measurements, which are very efficient according to the current state of investigations....

Endotoxin activity determination is a common tool and a surrogate marker for bioaerosol assessment and is used at workplaces especially for this purpose. The reliability of the methods used for quantification in airborne dust samples is important...

Polycyclic aromatic hydrocarbons (PAHs) are of particular relevance for occupational safety and environmental protection due to their ubiquitous occurrence in everyday life and at various workplaces and their persistent, bioaccumulative and toxic...

For the assessment of the exposure to hazardous substances at the workplace, the German technical rules for hazardous substances require that concentration peaks must be evaluated in addition to the shift exposure. Since in addition to the exposure...
