Dithiothreitol‐Measured Oxidative Potential of Reference Materials of Mineral Dust: Implications for the Toxicity of Mineral Dust Aerosols in the Atmosphere [PDF]

GeoHealth, 2023
Oxidative stress is a mechanism that might raise the toxicity of mineral dust aerosols. We evaluated the oxidative potential (OP) of four reference materials (RMs) of mineral dusts using dithiothreitol assay.

On mineral dust aerosol hygroscopicity [PDF]

Atmospheric Chemistry and Physics, 2020
Despite its importance, hygroscopicity of mineral dust aerosol remains highly uncertain. In this work, we investigated water adsorption and hygroscopicity of different mineral dust samples at 25 ∘C, via measurement of sample mass at different ...

Occupational exposure to gases/fumes and mineral dust affect DNA methylation levels of genes regulating expression. [PDF]

Hum Mol Genet, 2019
Many workers are daily exposed to occupational agents like gases/fumes, mineral dust or biological dust, which could induce adverse health effects. Epigenetic mechanisms, such as DNA methylation, have been suggested to play a role.

Technical note: Absorption aerosol optical depth components from AERONET observations of mixed dust plumes [PDF]

Atmospheric Measurement Techniques, 2019
Absorption aerosol optical depth (AAOD) as obtained from sun–sky photometer measurements provides a measure of the light-absorbing properties of the columnar aerosol loading. However, it is not an unambiguous aerosol-type-specific parameter, particularly

Mass deposition fluxes of Saharan mineral dust to the tropical northeast Atlantic Ocean: an intercomparison of methods [PDF]

Atmospheric Chemistry and Physics, 2014
Mass deposition fluxes of mineral dust to the tropical northeast Atlantic Ocean were determined within this study. In the framework of SOPRAN (Surface Ocean Processes in the Anthropocene), the interaction between the atmosphere and the ocean in terms of ...

Reflectance spectroscopy of indoor settled dust in Tel Aviv, Israel: comparison between the spring and the summer seasons [PDF]

Advances in Geosciences, 2007
The influence of mineral and anthropogenic dust components on the VIS-NIR-SWIR spectral reflectance of artificial laboratory dust mixtures was evaluated and used in combination with Partial Least Squares (PLS) regression to construct a model that ...

Aerosol–cloud–radiation interaction during Saharan dust episodes: the dusty cirrus puzzle [PDF]

Atmospheric Chemistry and Physics, 2023
Dusty cirrus clouds are extended optically thick cirrocumulus decks that occur during strong mineral dust events. So far they have mostly been documented over Europe associated with dust-infused baroclinic storms.

Technical Note: High-resolution mineralogical database of dust-productive soils for atmospheric dust modeling [PDF]

Atmospheric Chemistry and Physics, 2012
Dust storms and associated mineral aerosol transport are driven primarily by meso- and synoptic-scale atmospheric processes. It is therefore essential that the dust aerosol process and background atmospheric conditions that drive dust emissions and ...

The effect of (NH₄)₂SO₄ on the freezing properties of non-mineral dust ice-nucleating substances of atmospheric relevance [PDF]

Atmospheric Chemistry and Physics, 2021
A wide range of materials including mineral dust, soil dust, and bioaerosols have been shown to act as ice nuclei in the atmosphere. During atmospheric transport, these materials can become coated with inorganic and organic solutes which may impact their

Quantifying the range of the dust direct radiative effect due to source mineralogy uncertainty [PDF]

Atmospheric Chemistry and Physics, 2021
The large uncertainty in the mineral dust direct radiative effect (DRE) hinders projections of future climate change due to anthropogenic activity. Resolving modeled dust mineral speciation allows for spatially and temporally varying refractive indices ...
