    Abstract : Background: The negative effects of air pollution on morbidity and mortality have been known since the mid 20th century. The two most well known examples are the Meuse Valley disaster in the 1930’ies and the London black fog in December 1952. READ MORE

  4. 2. Effects of carbon dioxide and ozone on wheat crop yield and grain quality

    Author : Malin Broberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; koldioxid; ozon; vete; skörd; protein; stärkelse;

    Abstract : Atmospheric concentrations of carbon dioxide (CO2) and ozone (O3) have steadily increased since the industrial revolution. CO2 and O3 directly affect plant physiology, CO2 being an essential substrate for photosynthesis, while O3 is an oxidative agent causing damage to plant tissues. READ MORE

  5. 3. Removal of organic micropollutantns from wastewater in a Swedish context

    Author : Maja Ekblad; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treament; ozone; ozonation; pharmaceutical residues; Organic micropollutants; driving forces; drivers; avloppsvattenrening; ozon; ozonering; läkemedelsrester; organiska mikroföroreningar; drivkrafter;

    Abstract : Due to their potential environmental risk, the abatement of organic micropollutants from wastewater has gained increasing attention in recent years. This thesis evaluates the use of ozone in Swedish wastewater treatment plants (WWTPs) and the incentives for full-scale implementation of organic micropollutant removal. READ MORE

  6. 4. Application of chemical oxidation processes for the removal of pharmaceuticals in biologically treated wastewater

    Author : Gerly Hey; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The discharge of effluents from wastewater treatment plants (WWTPs) is considered to be the major source of residual pharmaceuticals frequently found in aquatic environments. The complex nature of such compounds tends to make conventional biological treatments aimed at their removal ineffective. READ MORE

  7. 5. Treatment of Wastewater Generated by Wood-based Dry Industries : Advances Oxidation Processes & Electrocoagulation

    Author : Henrik Hansson; William Hogland; Marcia Marques; Ollie Dahl; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Advanced oxidation processes; Electrocoagulation; Fenton; Industrial storm-water; Ozone; Respirometry assays; Wastewater; Wood floor industry.; Environmental Chemistry; Miljökemi;

    Abstract : Wood is a material with an enormous number of applications. For decades, the development of wastewater treatment technologies tailored for the wood sector has focused on those industries that have water as an integral part of the industrial production, such as paper and pulp.
