The perception of odours can cause concern among employees about possible health problems and is often a reason for complaints. The statutory accident insurance institutions have therefore been dealing with the determination and assessment of air...

Organotin compounds (OTC) rank among the most used organometallic compounds and have been utilized in various industrial sectors for several decades. Due to their high human and ecotoxicity, their use is already largely regulated. At workplaces, OTC...

The validation of a measurement method for the determination of hazardous substances in workplace air is concluded with the calculation of the expanded measurement uncertainty, which also determines whether the method is in accordance with DIN EN...

This article deals with the reduction of polychlorinated biphenyls (PCBs) from industrial flue gases. When chlorine-containing, peroxidic cross-linking agents are used, this group of pollutants is produced during the vulcanization of silicone rubber...

In the context of the revision of the EU Ambient Air Qualitiy Directive (2008/50/EC), measurement of ultrafine particles (UFP) in ambient air is proposed and discussed. To investigate the local ambient UFP concentration (immis- sion), exploratory...

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....
