In this study, Particulate Matter (PM) samples, collected during 2 summer and 2 winter months over a long-term period (1984–2012) at a suburban site in Athens (Greece), were used in order to examine the connection between Sahara dust long range transport events and mass concentrations of the aerosol mineral component, as well as the relative abundance of specific crustal components. As a result...

Precipitation was collected for a I-year period in Miami, Florida. The deposition rate of Al in samples containing Saharan dust was 10.1 ~g/cm2; this flux is equivalent to a mineral deposition rate of 126 ~g/cm2 per year, a value comparable to the mineral accumulation rate in sediments of the tropical North Atlantic. Mineral deposition rates in rain were highly variable, with 22% of the total o...

The EU-project MINATROC (MINeral dust And TROpospheric Chemistry) aims at enabling an estimation of the influence of mineral dust, a major, but to date largely ignored component of tropospheric aerosol, on tropospheric oxidant cycles. Within the scope of this project continuous atmospheric measurements of gas-phase HNO3 and SO2 were conducted in June and July 2000 at the CNR WMO station, situat...

Mineral dust emission accounts for a substantial portion of particles present in the troposphere. It is emitted mostly from desert areas, mainly through intense storm episodes. The aim of this work was to quantify sizesegregated fluxes of mineral dust particles emitted during storm events occurring in desert areas of northern China (Alashan desert, Inner Mongolia), known to act as one of the st...

Mineral dust particles include many different components, but are often treated by models as insoluble resulting in limited activation to cloud droplets. Experimental critical supersaturations of mineral dust particles 0.2 μm in diameter from different sources indicate that their composition is partially soluble. Using a Köhler model, the soluble fraction of each dust sample was calculated from...

BACKGROUND For individual exposures, effect modification by atopy or smoking has been reported on the occurrence of occupational airway disease. It is unclear if effect modification can be studied in a general population by an aggregated exposure measure. Assess relationship between airway obstruction and occupational exposure using a job-exposure-matrix (JEM) classifying jobs into 3 broad type...
