    Author : Sally Karlsson Bondesson; [2024]
    Keywords : avrinningsområde; belastning; fosfor; kväve; S-HYPE; retention; typområden på jordbruksmark; vattenflöde; VISS; våtmark;

    Abstract : Ett av Sveriges miljömål är ”ingen övergödning” vilket innebär att gödande ämnen inte ska ha negativ inverkan på människor, biologisk mångfald eller mark-och vattenanvändning (Naturvårds-verket 2023). Näringsämnena fosfor och kväve och förlusten av dessa från framför allt jordbruksmark är en av orsakerna till övergödning i sjöar, hav och vattendrag. READ MORE

  3. 7. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Hugo Möller; [2024]
    Keywords : Methanotrophs; organic micropollutants; co-metabolism; biodegradation; applied microbiology; Earth and Environmental Sciences;

    Abstract : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

  5. 9. Air quality around preschools in Gothenburg: an evaluation of measurement methods

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Emma Forsmalm; [2023-06-21]
    Keywords : low-cost sensors; passive diffusion samplers; pick-ups and drop-offs; regulatory measurements;

    Abstract : In this study the air quality around four different preschools, chosen to represent different local traffic environments, was measured and the measurement methods used were evaluated. The aim was to compare the information retrieved using different methods, discuss the possible applications of them and finally see if more specific activities, in this case pick-ups and drop-offs, could be seen in the data retrieved.
