1. Applications of the DGT technique for measurements of anions and cations in natural waters
Sammanfattning : Since the toxicity and mobility of trace metals are related to the metals' speciation, robust methods for trace metal speciation analysis are of great interest. During the last 15 years, hundreds of scientific articles have been published on the development and applications of the diffusive gradients in thin films (DGT) passive sampling technique. LÄS MER
2. Further characterisation and applications of the diffusive gradients in thin films technique : In situ measurements of anions and cations in environmental waters
Sammanfattning : As both the toxicity and the mobility of trace elements are related to chemical forms present, robust methods for element speciation analysis are of great interest. During the last 15 years, hundreds of scientific articles have been published on the development and applications of the diffusive gradients in thin films (DGT) passive sampling technique. LÄS MER
3. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters
Sammanfattning : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

4. Metal and microplastic treatment in stormwater bioretention
Sammanfattning : Metals and microplastic particles are common stormwater pollutants, which can be harmful when released to the environment. The aim of this thesis is to increase the understanding of the treatment of metals and their different fractions, as well as microplastic, in bioretention systems. LÄS MER
5. An evaluation of sources contributing to urban runoff pollution
Sammanfattning : Urban runoff is a significant pathway for the transport of diverse substances from the urban environment to receiving water bodies. Many of these substances are pollutants of environmental concern with potentially harmful effects on aquatic life. LÄS MER
