The results of the adaptation of the evaporation guideline VDI 3786-21 to climate change are presented. The focus is on physically based models, such as the Penman-Monteith model. The communication of empirical methods, whose parameters are no...

In Germany, around 350 institutes for human pathology conduct diagnostic tests on tissue samples, with formaldehyde playing a central role due to its important preservative properties. However, formaldehyde also poses a health risk as it is...

The UV irradiance and the UV index show pronounced spatial and temporal variability in Germany. Long-term changes in the frequency of occurrence of the exposure classes of the UV index according to the World Health Organization (WHO) [1] can be...

Poly- and perfluorinated alkyl substances (PFAS) have had a remarkable career due to their almost incredible technical and chemical properties, leading to a wide range of applications. The spectrum of uses ranges from “quite practical” (food...

Grid inspections can be used to determine the frequency of odour hours. During planning, execution and evaluation of grid inspections, various sources of error and uncertainties occur, for instance the suitability of assessors, the meteorological...

The determination of cristobalite in dust from workplaces is carried out using the established X-ray diffractometric (XRD) and infrared spectroscopic analysis methods, published as DGUV Information 213-582. In contrast to quartz, the composition of...

Humans and the environment in Germany and Europe continue to be exposed to frequently high concentra- tions of near-ground ozone. Various methods are available to assess the risks to vegetation. The flux-based risk assessment based on the phytotoxic...

Harm caused by moisture and mould is re- garded as one of the most relevant hazardous substance is- sues in indoor areas. The establishment of standardized methods for study of such harm has been stepped up in recent years. The methods include...

For years, routine active biomonitoring at the Billigheim hazardous waste landfill (Baden-Württemberg/Germany) has determined negligible, low-level immission impacts. Unexpectedly, in late summer 2022 high levels of mercury content were observed in...

The German AWMF mould guideline „Medical clinical diagnostics for indoor mould exposure“ – Update 2023 [2] (AWMF register no. 161/001) concludes that in case of visible mould infestation, the causes of the infestation shall be clarified...

: The testing of air purifiers for effectiveness is currently covered by a number of international standards, but these only cover a limited number of airborne contaminants. As a result, it is difficult to make a comparative assessment of the...

Polycyclic aromatic hydrocarbons (PAHs) are aromatic organic compounds which are formed during incomplete combustion processes and can exhibit carcinogenic and mutagenic properties. Up to now, the focus of analytical methods for PAHs in the context...

Long-chain alcohols usually have a high molecular weight, unbranched molecular structures and a primary alcohol as the end group. At shorter chain lengths they are present as colourless, oily liquids and take on a solid waxy form at longer chain...
