1. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Dissolved organic matter (DOM) in surface water has been widely studied, in part due to its significance for aquatic ecology and drinking water quality. Across Sweden, increases in the total organic carbon (TOC) concentrations and color of surface waters, known as brownification, were noted in the decades before and after year 2000, though recent analysis has found widespread DOM increase to have ceased after 2010.

2. Water quality and organic matter linkages in waters draining arable fields
University essay from SLU/Dept. of Soil and EnvironmentAbstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE

3. Hydrodynamic modelling of fate and transport of natural organic matter and per- and polyfluoroalkyl substances in Lake Ekoln
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden.

4. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. READ MORE

5. Mercury and methyl mercury release in soil and water - their relationship with different properties in Skogaryd
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : In Skogaryd research site, water samples were taken and analysed for total mercury (Hgtot) and methylmercury (MeHg) concentration along with the pH, dissolved oxygen (DO) and total organic content (TOC). This to give the condition of the site before the forest is clear-cute and a part of the land rewetted to a wetland. READ MORE
