2. 1. Dispersion modelling of volcanic emissions

   Author : Adam Dingwell; Rutgersson Anna; David Simpson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; dispersion modelling; atmospheric; volcano; gas emissions; volcanic ash; FLEXPART; FLEXPART-WRF; Spridningsmodellering; atmosfär; vulkan; gasutsläpp; vulkanaska; FLEXPART; FLEXPART-WRF; Meteorology; Meteorologi;

   Abstract : Gases and particles released by volcanoes pose a serious hazard to humans and society. Emissions can be transported over long distances before being reduced to harmless concentrations. Knowing which areas are, or will be, exposed to volcanic emissions is an important part inreducing the impact on human health and society. READ MORE

4. 2. Assessing environmental exposures. Air pollution in Scania, southern Sweden

   Author : Ralf Rittner; Avdelningen för arbets- och miljömedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; dispersion modelling; health impact assessment; emission database; Particulate matter PM ; epidemiology;

   Abstract : Background: The environment where we humans live provides the fundamental requirements we need to survive – food to eat, water to drink, and air to breathe. The quality of these elements has a major impact on human health, as they can contain substances that are detrimental to health. These we call environmental pollutants. READ MORE

5. 3. Quantification of population exposure and health impacts associated with air pollution

   Author : David Segersson; Christer Johansson; Lars Gidhagen; Ranjeet S. Sokhi; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; health impact assessment; dispersion modelling; population exposure; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : There is substantial evidence that air pollution, in particular particulate matter (PM), affects our health. The overall objective of this thesis is to understand and quantify population exposure to ambient air pollution and related health impacts. READ MORE

6. 4. Cardiovascular and pulmonary health effects of air pollution - long term effects in Sweden and effects of wood smoke

   Author : Leo Stockfelt; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; wood smoke; human exposure studies; dispersion modelling; cohort studies; cardiovascular disease;

   Abstract : Exposure to air pollution is associated with increased morbidity and mortality in cardiovascular and pulmonary diseases. Main suggested mechanisms are airway and systemic inflammation, affecting hemostasis in the short term and atherosclerosis in the long term. READ MORE

7. 5. Towards Dense Air Quality Monitoring : Time-Dependent Statistical Gas Distribution Modelling and Sensor Planning

   Author : Sahar Asadi; Achim Lilienthal; Amy Loutfi; Dominque Martinez; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mobile robot olfaction; time-dependent gas distribution modelling; temporal sub-sampling; sensor planning; artificial potential field; gas monitoring;

   Abstract : This thesis addresses the problem of gas distribution modelling for gas monitoring and gas detection. The presented research is particularly focused on the methods that are suitable for uncontrolled environments. READ MORE
