It is well known that fine dust is produced when materials are processed with ultrashort pulse lasers. However, a systematic characterization and toxicological evaluation of the released particles has been lacking until now. As part of a research...

Metalworking fluids (MWFs) when mixed with water provide a favorable growth environment for microorganisms due to their composition and operating conditions. Some of these microorganisms can cause skin and respiratory diseases in exposed workers....

This article builds on Part 1 of the study, in which open questions regarding the sampling of N-nitrosamines, potential emission sources and protective measures under the German Hazardous Substances Ordinance were discussed. The present paper...

Identification of major sources of dust deposition and its metallic content in industrial environments with multiple different facilities requires a higher spatial resolution than the Bergerhoff method provides. To this end, a dust deposition...

Powder coating plants are often considered an environmentally friendly alternative to coating plants for liquid coating materials containing volatile organic compounds (VOCs). Since the construction and operation of powder coating systems do not...

Gas metal arc welding is associated with health risks from inhalable hazardous substances. Exposure to carcinogenic chromium and nickel compounds can occur particularly when processing stainless steel grades. Exposures to respirable chromium and...

The ability of plants to remove fine dust depends on several factors. The influence of the flow situation and species-specific plant architecture on the removal efficiency of test plants such as ivy hedges and perennials is extensively characterised...

Effective removal of per- and polyfluoroalkyl substances (PFAS) from industrial gas streams through adsorption on granular activated carbon could be shown for the chemical manufacturing, waste treatment and environmental services sector at cost...

The VDI standard series 4250 Part 1 to 3 has undergone a comprehensive revision in recent years. This series addresses bioaerosols and biological agents and provides technical recommendations for the environmental health assessment of bioaerosols....

In Germany, around 130,000 people are employed in around 19,600 commercial gardening and landscaping businesses (GaLaBau). Due to the natural microbiological colonization, activities with plants and soil inevitably lead to the exposure of employees...

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...
