21. Multiple perspectives on absorbing aerosols over the northern Indian Ocean and Asia
Abstract : Aerosol particles in the atmosphere scatter and absorb solar radiation, and thereby affect the Earth's energy budget, but the magnitude of the overall radiative effect due to aerosol-radiation interactions is uncertain. In particular, the impact of absorbing aerosol particles, mainly black carbon (BC), organic carbon and dust, is not completely understood. READ MORE

22. Improved environmental monitoring and assessment : Establishing links between effects of chemical pollution at different levels of biological organization in a Baltic Sea bioindicator species (Monoporeia affinis)
Abstract : A large number of chemicals enters the marine environment via atmospheric deposition, run-off, rivers and streams, industrial effluents and municipal wastewater. To understand how chemicals affect environmental health, monitoring and assessment approaches need to combine physical, chemical and biological effect parameters from different levels of biological organization.

23. Urban Surfaces as Sources of Stormwater Pollution : An Evaluation of Substances Released from Building Envelopes
Abstract : Stormwater is an important transport pathway for pollutants from the urban environment into receiving water bodies, and, thus, it contributes to the deterioration of urban surface waters. The aim of this Licentiate thesis was to advance the understanding of the contributions of urban stormwater pollutants from building surface materials, and evaluate the implications for stormwater quality.

24. Lake Hydrodynamics and Pollution Transport under Climate Change : The Case of Lake Victoria
Abstract : A very small part of the total earth’s water is freshwater (only 2.5 %). Unfortunately, due to climate change and pervasive manmade activities, surface freshwater quality in many places of the world has become degraded. READ MORE

25. Mechanisms for the Influence from Ice Nucleus Aerosols on Clouds and their Indirect Effects: Cloud Modelling
Abstract : The role of multiple groups of primary biological aerosol particles (PBAPs) as ice nucleating particles (INPs), and of ice formation processes such as time-dependent freezing of various INPs, and various secondary ice production(SIP) mechanisms in overall ice concentration has been evaluated in a range of cloud systems by simulating them numerically with the state-of-the-art ‘Aerosol-Cloud’ (AC) model in a 3D mesoscale domain. Also, the mechanismsof aerosol indirect effects (AIEs) arising from anthropogenic INPs, and the responses to these AIEs from time-dependent INP freezing and SIP processes are investigated in the simulated clouds.
