1. 1. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Anna Lackner; [2022]
   Keywords : Dissolved Organic Matter; Brownification; Digital Mapping; Soil Moisture; Stream Length;

   Abstract : 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.

3. 2. 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

4. 3. Investigating the dynamics controlling dissolved organic matter bioreactivity in agricultural stream water and its link to carbon evasion : A statistical analysis

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Sara Schützer; [2022]
   Keywords : ;

   Abstract : While streams and rivers emit large quantities of CO2 to the atmosphere, both the mechanisms controlling CO2 evasion as well as the sources of CO2 are still uncertain. One potential source of stream CO2 is in-stream degradation of dissolved organic matter (DOM). READ MORE

5. 4. Distribution and transport of microplastics and metals in sewage sludge-amended agricultural soil : a Comparative study between microplastics copper, cadmium, and nickel

   University essay from SLU/Dept. of Soil and Environment

   Author : Nora Ottander; [2022]
   Keywords : Bioturbation; advective transport; earthworm; Aporrectodea longa;

   Abstract : This thesis investigated the vertical transport of microplastics and metals in agricultural soil after sewage sludge application. Sewage sludge is commonly used in agriculture for adding nutrients and carbon to improve the soil quality. READ MORE

6. 5. An implementation of an autonomous IoT system for real-time water quality monitoring with 4G and satellite connection : CatFish - Embedded systems

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Johan Elfing; Daniel Persson; [2022]
   Keywords : CatFish; Embedded System;

   Abstract : This thesis is about implementing an Internet of Things system for measuring water quality in rivers and other aquatic environments with an autonomous water drone, where the data from various components are collected and sent wirelessly to the database in real-time. A Raspberry Pi is connected to the internet through a 4G modem and a wireless satellite communication connection called RockBlock for emergency calls and notifications. READ MORE
