A method has been developed to screen large numbers (~103–104 per sample) of coarse airborne dust particles for the occurrence of Pb-rich phases, together with quantification of the particles’ mineralogy, chemistry, and inferred provenance. Using SEM-EDS spectral imaging (SI) at 15 kV, and processing with the custom software PARC, screening of...

Camera systems are widely used for surveillance in the security and defense domains. The main advantages of camera systems are their high resolution, their ease of use, and the fact that optical imagery is easy to interpret for human operators. However, particularly when considering application in the defense domain, cameras have some...

The focus in this study is on very metal dusting resistant nickel chromium alloys with a high content of chromium (in the range of 22 to 33 wt.%), additions of aluminum (between 0 and 3 wt.%) and variable iron content (between 0.1 and 15 wt.%). All samples were exposed up to 5693 h at 600 °C in a 37 vol.% CO, 7 vol.% CO2, 46 vol.% H2, 9 vol.%...

Aerosol optical depths (AODs) from the new Himawari-8 satellite instrument have been assimilated in a dust simulation model over East Asia. This advanced geostationary instrument is capable of monitoring the East Asian dust storms which usually have great spatial and temporal variability. The quality of the data has been verified through a...

In previous studies, a number of model-based dust forecasts and early warning systems have been developed for the prevention of environmental impacts due to dusts. However, the accuracy of the model is limited by imperfect identification of dust emissions, in particular by the friction velocity threshold parameterization in the emission process....

The Advanced REACH Tool (ART) is the most sophisticated tool used for evaluating exposure levels under the European Union's Registration, Evaluation, Authorisation and restriction of CHemicals (REACH) regulations. ART provides estimates at different percentiles of exposure and within different confidence intervals (CIs). However, its performance...

ECN has developed a simple and inexpensive method to prevent clogging of dust in capillary columns of mass spectrometers or gas chromatographs. In some processes there are dust particles present in the process gas. The method developed by ECN is a smart solution that helps to prevent that dust particles end up in the analyzer.

Although previous studies report on the effect of street washing on ambient particulate matter levels, there is a lack of studies investigating the results of street washing on the emission strength of road dust. A sampling campaign was conducted in Madrid urban area during July 2009 where road dust samples were collected in two sites, namely...

An intervention study with a decentral electrostatic filter has been carried out in a nursery. The field study shows that it is possible to reach a reduction up to 80% of ultra-fine (<0.1 μm) and up to 68% for the PM1 and PM2,5-PM1 fractions at a relatively low energy consumption. These particle fractions were mostly determined by the outdoor...

Quartz exposure can cause several respiratory health effects. Although quartz exposure has been described in several observational workplace studies, well-designed intervention studies that investigate the effect of control strategies are lacking. Tis article describes a baseline exposure study that is part of a multidimensional intervention...

Scope: Due to the imminent growth of the world population, shortage of protein sources for human consumption will arise in the near future. Alternative and sustainable protein sources (e.g. insects) are being explored for the production of food and feed. In this project, the safety of Yellow mealworms (Tenebrio molitor L.) for human consumption...

About 400,000 premature adult deaths attributable to air pollution occur each year in the European Region. Road transport emissions account for a significant share of this burden. While important technological improvements have been made for reducing particulate matter (PM) emissions from motor exhausts, no actions are currently in place to...

In the last decade, studies on indoor air pollution suggest a link between exposure to indoor particulate matter and compounds, in particular ultrafine particles and secondary organic aerosols, and several health effects. The mechanisms of how those complex mixtures relate to health effects are still not fully understood. In vitro testing, i.e.,...

Corrosion protection of ballast water tanks is very precarious because of the aggressiveness of the environment and the difficult accessibility of the areas. Numerous accidents have led to regulation by the International Maritime Organization (IMO). Practical circumstances in yards are often not ideal; therefore it is of interest to investigate...

It is generally known that the production route influences the sensitivity of a material to metal dusting. In this study the different production states of UNS N06025 are compared as there are: plate deeply ground and 600 grit laboratory ground, strip as-delivered and 600 grit laboratory ground, and longitudinally welded tubes as-delivered and...

Aerosol Optical Depth (AOD) and Ångström exponent (AE) values derived with the MODIS retrieval algorithm over land (Collection 5) are compared with ground based sun photometer measurements at eleven sites spanning the globe. Although, in general, total AOD compares well at these sites (R 2 values generally over 0.8), there are cases (from 2 to...

The Advanced REACH Tool (ART) is an exposure assessment tool that combines mechanistically modelled inhalation exposure estimates with available exposure data using a Bayesian approach. The mechanistic model is based on nine independent principal modifying factors (MF). One of these MF is the substance emission potential, which addresses the...
