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...

In view of the trend towards growing vegetables in the immediate vicinity of roads in urban areas, a pilot study was carried out to investigate the impact of road traffic on food crops. For this purpose, the bioindicators kale, chard, lollo rosso...

Exposure measurements are subject to large uncertainties. Therefore, this article presents statistical methods to answer the title question. They rest on sufficiently large samples for tests to accept a distribution. In a second step, the parameters...

To ensure healthy indoor environments in houses the identity and concentrations of very volatile organic compounds (VVOC) are important factors. Passive samplers are often used in environmental surveys e.g. “German Environmental Survey” to...

A micro-scale emission test chamber-based method to determine air concentrations of volatile organic compounds (VOCs) emitting from consumer products within the first hours of product use was compared in a round robin test. Pieces of a rain poncho...

A key focus of the amendment to the German Hazardous Substances Ordinance (GefStoffV) is the prevention of work-related cases of cancer. The core element of this prevention approach is the risk-based concept for preventive measures relating to...

Ensuring good indoor air quality in schools is essential for the health and performance of students and teachers. At the same time, this represents a challenge given the energy-efficient use of buildings. Studies show that passive ventilation is...

This article describes the occupational risk assessment for isocyanate applications using the TRGS 430. Different types of occupational exposure limits and the prevention of dangerous acut toxic exposures and occupational illnesses are presented....
