1. 1. Influence of Wastewater DOM Fractions on the Adsorption of Pharmaceuticals onto Activated Carbon

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Koustubh Karande; [2022]
   Keywords : Wastewater treatment; Dissolved organic matter; Pharmaceuticals; Activated carbon; Hydrophobicity; Molecular weight; Water resources engineering; Technology and Engineering;

   Abstract : Micropollutants in our sources of freshwater is an issue which requires immediate attention. The presence of pharmaceuticals, endocrine disrupting agents, pesticides and other harmful compounds have proven to have impact on the aquatic as well as on human life. READ MORE

3. 2. Leachate-Based Biotic Ligand Model for Soil : Ecotoxicological Risk Assessment of Copper for Invertebrates, Plants, and Soil Microbial Processes

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Tove Florén; [2021]
   Keywords : Tomato shoot; Barley root; Glucose induced respiration; Nitrification; Earthworm; Springtail; EC10; SSD; Regression analysis; pH dependency; Bioavailability;

   Abstract : Environmental pollution of heavy metals has become an increasing problem. Environmental risk assessments can be conducted to investigate and determine the potential risk of polluted terrestrial environments. Traditionally, risk assessments are based on total soil metal concentrations on a dry weight basis. READ MORE

4. 3. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Nora Kainz; [2021]
   Keywords : physical geography; ecosystem analysis; permafrost degradation; DOC; DOC concentration; stable isotope carbon signature; DOC quality; DOC degradation; Atmospheric Sciences and Biogeochemical Cycles; Earth and Environmental Sciences;

   Abstract : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.

5. 4. Effects of drought on waterchemistry in a boreal streamnetwork

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Enrique Gómez de Salazar Martínez; [2021]
   Keywords : : drought; boreal streams; Krycklan Catchment Study; land cover; biogeochemistry;

   Abstract : Hydrological drought at high latitudes represents a rising environmental hazard induced byglobal climate change. Yet, we still know little about how drought events influence thebiogeochemistry of boreal streams. READ MORE

6. 5. Development and Testing of a Hydro-Chemical River MixingModel to Investigate Sources of Carbon and Mercury in the Mackenzie River Basin, Canada

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Torbjörn-Johannes Erikson; [2020]
   Keywords : mercury; Hg; POC; DOC; Mackenzie River; kvicksilver; Hg; DOC; POC; Mackenziefloden;

   Abstract : Mercury, Hg, is found in Arctic biota in alarming quantity, posing a potential health risk for the local population. It is believed that the large Arctic rivers contribute to this. The Mackenzie River annually transports approximately 325 km3 water to the Arctic Ocean, which is ca 10% of the freshwater received. READ MORE
