Odours in ambient air that cause a feeling of disgust and nausea are considered harmful effects on the environmental according to the Federal Immission Control Act (BImSchG) - regardless of whether they cause significant odour annoyance. In this...

Proteins from microbially contaminated metalworking fluids (MWFs) can induce an occupational disease known as „machine operator’s lung.“ This disease is a special form of hypersensitivity pneumonitis (HP), an immunologically mediated disease...

Air purification systems in pig-fattening farms provide favorable conditions for the growth of potentially pathogenic microorganisms such as Legionella pneumophila, due to moderate temperatures, high nutrient availability, and water stagnation....

The measurements provide a deeper understanding of particle release during the fettling processes of aluminum and ferrous castings. A combination of continuous measurement technology and a decentralized Bluetooth mesh sensor network is employed to...

The basic suitability of two collection systems with wind direction-independent ring slot probes for the isokinetic sampling of bioaerosols in open-ventilated barn systems was investigated: firstly, in a test channel a newly developed ring slot...

Field inspections by grid method can be used to determine the odour hour frequency. When planning, conducting and executing field inspections by grid method, various sources of error arise in combination with the selection of panel members,...

For reliable risk assessment of airborne biological agents, it is essential to optimize the entire bioaerosol analytics process from collection to analysis. In this study, quartz fiber and polyethylene sulfone (PES) filters were compared with...

Currently, the limit value for exceptions to the ban on working with asbestos-containing materials permitted under the Hazardous Substances Ordinance according to the so-called exposure-risk relationship model is an acceptable concentration of...

The amended Hazardous Substances Ordinance (GefStoffV), which has been in force since December 2024, also contains new asbestos regulations in addition to the risk concept for handling carcinogenic hazardous substances, which has been enshrined in...

The intra-urban variability of heat stress in the city of Freiburg im Breisgau, characterized by one of the warmest climates in Germany, is investigated using observational data. Eight inner-city and two rural meteorological stations, distributed...

Although indoor heat is linked to outdoor heat, the former is of particular importance due to the length of time spent indoors, especially at night. In hospitals, this affects not only patients but also clinical staff. Considering that indoor heat...

Using the example of the Lech-Stahlwerke in Meitingen, in the area of which an extensive deposition measurement network for dust and metals has been in operation since 2007, a comparison of dispersion calculations according to the old and new TA...

Dust is usually formed during the handling of bulk materials and similarly stressed materials. How much dust is generated depends, among other things, on the material properties, the type of stress and also the material moisture. In terms of air...

Farms in the Upper Rhine region face particular challenges due to their geographical location and the effects of climate change. This study analyses the thermal stress, particularly heat stress in summer, of dairy cows in 16 farms (137 m to 1 037 m...

Low-cost aerosol sensors offer promising prospects for monitoring workplace atmospheres. The study summarized in this article was conducted jointly by a number of European research organisations, including the French Institut national de recherche...

Since the decline in large-scale pollution by acidifying air pollutants (especially SO2, NOX), the exposure of the epiphytic lichen Hypogymnia physodes has become less important according to the standard VDI 3957 Part 21. However, its particular...

The Bavarian Environment Agency (LfU) set up and commissioned three measuring stations to record ultrafine particles (UFP) at sites in Augsburg (LfU), Munich (Johanneskirchen), and Regensburg (university) in the urban background, with the sites...
