  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

  5. 5. Effect of Ibuprofen on the growth of Pseudokirchneriella subcapitata

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Mario Flos Berga; [2022]
    Keywords : P. subcapitata; toxicity test; contaminants of emerging concern; Ibuprofen;

    Abstract : Pharmaceuticals are an important class of pollutants in aquatic ecosystems. Detected concentration are typically in the range 1 ng/L – 1 μg/L. Traditional wastewater treatment does not provide a complete removal of these contaminants; hence, they may have a negative impact on the environment. READ MORE
