2. Emission of methane from northern lakes and ponds
University dissertation from Stockholm : Institutionen för geologiska vetenskaperAbstract : Northern lakes and ponds are abundant and emit large amounts of the potent climate forcer methane to the atmosphere at rates prone to change with amplified Arctic warming. In spite of being important, fluxes from surface waters are not well understood. READ MORE

3. Predictive Modelling of Heavy Metals in Urban Lakes
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : Heavy metals are well-known environmental pollutants. In this thesis predictive models for heavy metals in urban lakes are discussed and new models presented. The base of predictive modelling is empirical data from field investigations of many ecosystems covering a wide range of ecosystem characteristics. READ MORE
