Poor indoor air quality is an important issue for public and occupational health worldwide. Location, air-tightness of the building, ventilation rate and resident activities play an important role on the concentration of indoor pollutants and subsequently on their effects on human health. While indoor air pollution in working environments has...

Within the steelmaking industry, a large amount of zinc-bearing waste is produced which cannot be effectively treated through integrated steel mills. Concurrently, zinc smelters generate waste residues containing significant amounts of iron and zinc which are stored or landfilled. The zinc concentration of iron and steelmaking residues...

Asian mineral dust has been studied extensively for its role in affecting regional-to global-scale climate and for its deposits, which enable reconstructing Asian atmospheric circulation in the past. However, the timing and origin of the dust deposits remain debated. Numerous loess records have been reported across the Asian continent with...

The change in physical properties of wood pellets, with a focus on particle size distributions due to pellet breakage and attrition, was studied in a large-scale (∼450 ton/h) transportation system. Critical locations with a high probability of breakage through the whole transportation system were chosen and sampled to study the effect of...

During the production of steel, a dust waste stream is created that contains a significant amount of zinc which makes it difficult to treat and to recycle. Various furnaces have been developed that can deal with those dusts like rotary hearth furnaces and the DK process but none are fully optimal yet. HIsarna, a furnace in development by Tata...

Atmospheric aerosol particles are solid or liquid particles suspended in the atmosphere. They are directly emitted into the atmosphere or they are formed via the oxidation of gaseous precursors. Understanding the behavior of particles in the atmosphere is particularly important because they can affect the Earth’s climate, visibility, air quality...

The steelmaking industry produces large quantities of zinc-bearing wastes of varying forms that cannot be treated through integrated steelmaking processes. Simultaneously, by-products of the zinc industry containing great amounts of iron and zinc are stored or landfilled. The amount of zinc in these materials is generally below that which is...

Severe dust storms present great threats to the environment, property and human health over the areas in the downwind of arid regions. Several dynamical dust models have been developed to predict the dust concentrations in the atmosphere. Currently, the accuracy of these models is limited mainly due to the imperfect modeling of dust emissions....

The main waste products of ironmaking at Tata Steel IJmuiden are CO2¬(g) and a solid waste stream consisting of mainly carbon and iron-bearing compounds. This solid waste is generally called Zn rich filter cake which contains too much Zn to be reintroduced into the iron making process. Besides Zn, Pb and Cd are also present. These filter cakes...

The harmattan is a seasonal phenomena in West Africa. It is a dry and warm wind which is able to transport large dust plumes. This study aims to get insight in possible triggers that may have influence on the harmattan season itself.To find a seasonal predictor which can predict the intensity of the next harmattan season, historical data is...

When sawing in bone for medical or medico-legal procedures, fine, airborne dust is produced (aerosols) that can pose a health hazard when inhaled by practitioners. The goal of the current study was to find the influence of saw blade frequency and saw blade contact load, the degree of skeletonisation of the bone, the test environment with...

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...

When sawing bone for medical or medico-legal procedures, fine, airborne dust is produced (aerosols) that can pose a health hazard when inhaled. The aim of this study was to determine the influence of saw blade frequency and contact load, bone condition, test environment, and saw blade type, on the production of aerosol particles. A custom...

Metal dust deflagrations have become increasingly common in recent years. They are also more devastating than deflagrations involving organic materials, owing to metals' higher heat of combustion, rate of pressure rise, explosion pressure and flame temperature. Aluminum finishing operations offer a particularly significant hazard from the...

When sawing during autopsies on human remains, fine dust is produced, which consists of particles of sizes that may fall within the human respirable range, and can act as vectors for pathogens. The goal of this study was to explore the potential effects of saw blade frequency and saw blade contact load on the number and size of airborne bone...

We present [C ii] 158 μm measurements from over 15,000 resolved regions within 54 nearby galaxies of the Kingfish program to investigate the so-called [C ii] "line-cooling deficit" long known to occur in galaxies with different luminosities. The [C ii]/TIR ratio ranges from above 1% to below 0.1% in the sample, with a mean value of 0.48 ± 0...

Dust explosibility is traditionally described by two parameters, namely the maximum explosion pressure, P<sub>max</sub>, and the deflagration index, K<sub>St</sub>, usually determined through testing in a closed, pressure-resistant spherical vessel, either 20 L or 1 m<sup>3</sup> in volume. These parameters constitute key variables in the...

Dust has negative effects on the environmental conditions, human health as well as industrial equipment and processes. In this thesis, the transfer point of a belt conveyor as a bulk material handling system with a very high potential place for dust liberation is studied. This study is conducted based on experimental and numerical methods as...

The habitability of exoplanets is determined by their surface properties and atmospheres, spectropolarimetry is a powerful tool to characterize these. Numerical models can be used to simulate the polarimetric signals of these exoplanets, but these computed signals have to be compared with observations. The best test-case for such a comparison is...
