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...

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...
