  1. 11. Green Anesthesia : Use of Inhalational Anesthetics and their Effect on our Climate

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Sabina Karchut; Skylar Wedahl; [2023]
    Keywords : MAC – minimum alveolar concentration; GWP – global warming potential; CO2 – carbon dioxide; N2O – nitrous oxide; Low-Flow Anesthesia; sevoflurane; isoflurane; desflurane; FGF – fresh gas flow; MAC – minimum alveolar concentration; GWP – global warming potential; CO2 – koldioxid; N2O - lustgas; Lågflödesanestesi; sevofluran; isofluran; desfluran; FGF – färskgasflöde;

    Abstract : This thesis has, commissioned by Dräger, an international company at the forefront of medical and safety technology, examined how the use of inhalational anesthetics affects the climate and environment. The purpose of this work is to examine how the Swedish healthcare sector currently works with inhalational anesthetics, how different anesthetic machines affect the emissions, as well as alternatives available to reduce anesthetic gases emissions.

  3. 12. Emission of greenhouse gases from constructed wetlands : Nutrient status in relation to methane and nitrous oxide emission

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Christian Lundström; [2022]
    Keywords : Constructed wetland; greenhouse gas emission; nutrient status; ebullition; Anlagd våtmark; växthusgasutsläpp; näringsstatus; ebullition;

    Abstract : Agricultural land releases large amounts of nitrogen and phosphorus to water bodies which causes eutrophication. Creating wetlands on agricultural land is one way to prevent this major issue. However, constructed wetlands are a large emission source of greenhouse gases. READ MORE

  4. 13. Effects of cover crops on nitrous oxide (N2O) emissions in cereal cropping

    University essay from SLU/Dept. of Ecology

    Author : Khadija Aziz; [2022]
    Keywords : cover crops; nitrous oxide; C sequestration; greenhouse gases; off-season emissions; freeze-thaw cycles;

    Abstract : More than 60% of anthropogenic nitrous oxide (N2O) emissions are attributed to agricultural activities. N2O production in soils highly depends on the N availability along with other factors such as soil moisture content, which provide suitable conditions for nitrification and denitrification.

  5. 14. Controls of the partitioning of nitrate between DNRA and denitrifiers

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Frida Lindvall; [2022]
    Keywords : DNRA; denitrification; microcosm; experiment; arable soil;

    Abstract : In arable soils, the importance of denitrification, a respiratory process where nitrate (NO3-) is stepwisely reduced to nitrogen gas and nitrous oxide (N2O) is well established. More recently has dissimilatory nitrate reduction to ammonium (DNRA) gained interest as its importance in agricultural soils might have been largely overlooked. READ MORE

  6. 15. Emissions of nitrous oxide associated with frost killed cover crops

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Felicia Olofsson; [2022]
    Keywords : Nitrous oxide; cover crops; greenhouse gases; freeze-thaw cycles;

    Abstract : Agriculture is responsible for approximately 80% of anthropogenic emissions of the potent and long-lived greenhouse gas nitrous oxide (N2O). N2O emissions from agricultural soils are characterized by high temporal and spatial variability and often peak in short bursts related to events such as precipitation, fertilization and soil thawing.
