1. 1. Modelling the risk of rainfall events leading to momentary pollution levels exceeding maximum allowed concentrations - A Swedish case study of urban runoff in the Fyris river

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Tove Gannholm Johansson; [2022]
   Keywords : urban runoff; flow; rain event; pollution concentration; EQS; MAC-EQS; dagvatten; flöde; regntillfälle; föroreningskoncentration; MKN; MAC-MKN;

   Abstract : The purpose of this study was (1) to study the proportion (X) of the flow in a watercourse that consists of urban runoff during a rain event and (2) to evaluate the risk that a few chosen pollutants, transported by urban runoff, exceed the maximum allowed concentration in the watercourse according to the environmental quality standards (MAC-EQS). The Fyris river in Uppsala, Sweden, was selected as a case study. READ MORE

3. 2. Resilience in urban hydrology : A study of storm water management in the municipality of Stockholm

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Boel Lindberg; [2019]
   Keywords : Storm water management; Storm water; Stormwater; Blue structures; Resilience in infrastructure; Urban runoff;

   Abstract : The environmental issues of storm water in the urban environment is addressed in political policies on many different governance levels. The concept of “sustainable storm water” in Europe uses the natural water cycle as a template for urban drainage, and the EU has a water framework directive (WFD) with a systems approach, using drainage basins as the starting point of all actions.

4. 3. Trophic transfer of per- and polyfluoroalkyl substances (PFASs) by glacial relicts in Lake Vättern, Sweden

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Malin Bergman; [2017]
   Keywords : ;

   Abstract : The aim with the study was to assess if glacial relict amphipods constitute as vectors of transport of per- and polyfluoroalkyl substances (PFASs) in the Arctic char food web in Lake Vättern, Sweden. Sediment, surface water and biota samples were analysed for PFASs using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and stable isotope analysis of δ 13C and δ15N was performed on sediments and biota samples.

5. 4. The Metal Content in Airborne Particles in Landskrona

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Wouter Prosper; [2017]
   Keywords : Earth and Environmental Sciences;

   Abstract : Landskrona has for a long time had problems with high concentrations of Pb and other heavy metals in the air. Measurements investigating the content of airborne particles have been performed in 1977, 1988, 2003 and 2008 and show an influence from heavy industries, traffic in town and transboundary pollution.

6. 5. Water framework directive mixing zone guidelines : applied on a smelter and mine scenario at two Boliden sites

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

   Author : Arnola Çeka; [2011]
   Keywords : EU-WFD; Mixing Zone; Environmental Water Quality Standards; Discharge Test; CORMIX; Priority Substances;

   Abstract : The Water Framework Directive (WFD) aims to protect the aquatic environment and human health by reducing pollutants at the source. In order to achieve this, the concentration of priority substances should be lower than Environmental Quality Standards (EQS) values at the point sources. READ MORE
