  2. 6. Ozone and diesel exhaust : airway signaling, inflammation and pollutant interactions

    Author : Jenny Bosson; Anders Blomberg; Thomas Sandström; Ellinor Ädelroth; John Balmes; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; ozone; diesel exhaust; airway inflammation; asthma; immunohistochemistry; Lung diseases; Lungsjukdomar; lungmedicin; Lung Medicine;

    Abstract : It is well established that air pollution has detrimental effects on both human health as well as the environment. Exposure to ozone and particulate matter pollution, is associated with an increase in cardiopulmonary mortality and morbidity. Asthmatics, elderly and children have been indicated as especially sensitive groups. READ MORE

  4. 7. Machine Learning Approaches to Develop Weather Normalize Models for Urban Air Quality

    Author : Chau Ngoc Phuong; Mengjie Han; Rasa Zalakeviciute; Ilias Thomas; Mario Salvador González Rodríguez; Högskolan Dalarna; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Weather Normalized Models WNMs ; Air Pollution; Data-Driven Modeling and Optimization; Deep Learning - Artificial Neural Network DL-ANN ; Machine Learning;

    Abstract : According to the World Health Organization, almost all human population (99%) lives in 117 countries with over 6000 cities, where air pollutant concentration exceeds recommended thresholds. The most common, so-called criteria, air pollutants that affect human lives, are particulate matter (PM) and gas-phase (SO2, CO, NO2, O3 and others). READ MORE

  5. 8. Airway antioxidant responses to oxidative air pollution and vitamin supplementation

    Author : Annelie Behndig; Anders Blomberg; Ian S Mudway; Ragnberth Helleday; Isabelle Romieu; Umeå universitet; []
    Keywords : Medicine; air pollution; ozone; diesel exhaust; airway inflammation; antioxidant; vitamin C; dehydroascorbate; vitamin supplementation; Medicin; lungmedicin; Lung Medicine;

    Abstract : Air pollutants, such as ozone (O3) and diesel exhaust particles, elicit oxidative stress in the lung. Antioxidants within the respiratory tract lining fluid (RTLF) protect the underlying tissue from oxidative injury. READ MORE

  6. 9. Application of ozone in wastewater treatment : Oxidation of pharmaceuticals and filamentous bulking sludge

    Author : Filip Nilsson; Avdelningen för kemiteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ozone; Filamentous Sludge; Pharmaceuticals; Wastewater Treatment; Ozone; Filamentous bulking sludge; Pharmaceutical reduction;

    Abstract : As pharmaceutical removal was not part of the of the modern wastewater treatment plant (WWTP) design, it is not surprising that WWTPs have been identified as major point sources of pharmaceuticals entering the environment. The oxidation of pharmaceuticals in the WWTP effluent is one of the-end-of-pipe solutions that are considered most ready for full-scale use. READ MORE

  7. 10. The impact of mesospheric dynamics and chemistry on key chemical species: 20 years of Odin/SMR satellite observations

    Author : Francesco Grieco; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mesosphere; energetic particle precipitation; H2O; NO; atmospheric solar tides; microwave limb sounding; CO;

    Abstract : Coupling mechanisms between different atmospheric layers are such that changes in middle atmospheric dynamics and composition have an effect on what happens at lower altitudes and on the climate. There is therefore a need to extend climate models to include higher altitudes and to perform measurements of the middle atmosphere. READ MORE
