Condensable particulate matter (CPM) from small combustion plants (SCPs) has often been inadequately accounted for in emission inventories, despite making a significant contribution to total particulate emissions. In this study, emission factors for...

This article continues the description of a study, in which nitrosamine sampling strategies, emission sources, and the risk and mitigation of artefact formation by precursor substances are investigated. Volatile nitrosamines are assumed to pose a...

PFAS are a recurring topic in daily newspapers, trade journals, and other media. The focus is usually on the persistence of these substances – also known as “forever chemicals” – on widespread PFAS contamination, or on planned EU regulations...

The determination of the required stack height in accordance with No. 5.5 of the Technical Instructions on Air Quality Control (TA Luft) aims to ensure an undisturbed discharge and sufficient dilution of exhaust gases. However, for sources with...

Filling activities of containers with acids and bases can be found in many enterprises and branches. Using the measurement strategy developed for filling of containers with organic liquids [1] and bulk material [2], the Federal Institute for...

A literature review identified 72 publications whose underlying studies used methodological approaches based on the VDI standards (series of standards VDI 3957) pertaining to cryptogams (lichens, bryophytes). The compilation shows that most of the...

Since 1972, the MEGA exposure database at the Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA) has documented over four million records on workplace exposure to hazardous substances and biological agents,...

Assessment criteria such as occupational exposure limit values or maximum workplace concentrations are used for the evaluation of air quality in the workplace or respiratory exposure of workers to metals and their compounds (among other...

The article systematically highlights key aspects of climate adaptation in cities and the effect on humans and provides technical details. The actual mechanisms of action of various measures such as greening, reflective surfaces, water misters, blue...

The correlation for formaldehyde emission testing of flooring installation products (adhesives) and floor surface treatment products between test results obtained by EN 16516 “Construction products: Assessment of release of dangerous substances...

The CycloPlasma process combines cyclodextrin coatings (β-CyD) with non-thermal plasma (NTP) for decontaminating lindane- and (pentachlorophenol) PCP-contaminated wooden structures. Laboratory studies using thermoextraction and emission chamber...

In early summer 2025, the Environmental Action Germany (DUH) presented the results of its Heat-check 2.0 study for 190 cities in Germany with more than 50 000 inhabitants. They are based on a heat impact index (HBI), which was determined exclusively...

Mineral fibre-based insulating systems typically contain components that decompose under exposure to temperatures above approximately 150 °C. Under these conditions, a large number of harmful substances are released from binders in mineral wools,...
