1. 1. Effects of plastic pollution on leaf litter decomposition in Swedish freshwater ecosystems : a field study addressing recently and globally emerging pollutants

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

   Author : Martina Stangl; [2022]
   Keywords : Microplastics; Face masks; Ecosystem functioning; Leaf decomposition; Field study;

   Abstract : Plastic pollution is recognized as an increasing environmental problem, but few studies have addressed impacts on ecosystem functions, and very few have been conducted in the field. This study investigated the effects of polypropylene particles derived from disposable face masks on in-situ leaf litter decomposition processes in freshwater ecosystems. READ MORE

3. 2. 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

4. 3. Microplastics in the Gulf of Bothnia, SwedenA comparison between Österfjärden and Örefjärden.

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Emma Overgaard; [2021]
   Keywords : IR; Microplastic; pollution; polymer composition; surface water; visual characterization;

   Abstract : Microplastics are emerging pollutants in the marine environment, including a range of polymers modified by varying quantities of additives and sorbed pollutants, differing in size, colour, and shape. This study focuses on characterization and quantification through visual characterization of microplastics >300 μm in surface water and at 5-meter depth in the Gulf of Bothnia. READ MORE

5. 4. Indoor and Outdoor Measurements of Particulate Matter with the Low-Cost Optical Sensor OPC-N3

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

   Author : Ellen Grace Soroka; [2020]
   Keywords : Physics and Astronomy;

   Abstract : This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. READ MORE

6. 5. A study of the performance of biochar as adsorbing agent in o‐DGT devices

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Anna Eliasson; [2017]
   Keywords : Biochar; o‐DGT; DGT; emerging pollutants; organic pollutants; environmental chemistry; wastewater; wastewater treatment; contaminants; hormone disruptors;

   Abstract : A new complex aspect in the matter of water quality is the occurrence of emerging organic pollutants and contaminants in waste water. The currently low extent to which treatment of waste water is performed in Brazil, and in the world as a whole, there is a considerable need for development of cheap and accurate in-situ sampling methods for far-reaching studies of surface water quality.
