There is increasing evidence for high magnitude dust storms in high latitude environments. Yet, Aeolian processes in these areas have been largely understudied and therefore our knowledge of these systems is limited. Understanding dust emission processes from the high latitudes regions is of increasing importance because future climate scenarios indicate a reduction in terrestrial ice masses and an expansion in glacial outwash plains which are the main dust sources in high latitude environments. Of these regions, Iceland is the most researched high latitude dust source region, however our understanding of processes which lead to dust events are still poorly understood. This thesis examines the interlinking relationship between dust source and dust particle sedimentology and the physical and meteorological drivers which promote or inhibit dust emission in Iceland. This is achieved through active aeolian monitoring at source during two monitoring periods at Markarfljot, South Iceland. These measurements are complimented using secondary data sources (e.g. meteorological and satellite data), sedimentological mapping and particle analysis and laboratory abrasion experiments. This thesis is the first high resolution multi event record of dust emissions in the high latitudes and concludes by showing that potential dust concentrations and dust particle size are driven by the interlinking relationship between wind speed, sediment texture and surface moisture. Factors that affect the potential sediment availability for dust events are more important in the high latitudes than in the subtropics in driving spatial and temporal variability in dust emission. Measurements presented in this thesis are required to verify and tune regional and global modelling attempts to quantify the potential contribution of high latitude dust in the Earth system. However, further measurements are required to fully understand seasonal changes in dust emissions, across a variety of dust source units within all high latitude dust source regions.

This thesis deals with the issue of air pollution, emission of solid substance in the large-scale poultry. Compares the level of surface contamination inside the breeding facility, depending on the age of the poultry. The measurements were carried out in accordance with the applicable methodology for the evaluation and the determination of the concentration of dust particles PM10 in the selected large-scale poultry. Measurement was carried out in a large-scale broiler Farma u lesa in Sudoměřice u Bechyně. The aim of this work was to obtain a measurement and then evaluate the data obtained. The measurements were carried out in two rounds to measure two size fractions of solid pollutants. The DUST TRAK 8530, borrowed by the faculty, was used to measure the solid dust particles in bulge. Further, the thesis also describes description and measurement methodology with this device.
