   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Solal GAUDIN; [2023]
   Keywords : Short chain Chlorinated Paraffins SCCP Medium chain Chlorinated Paraffins MCCP Long chain Chlorinated Paraffins LCCP Recycled plastics Qualitative analysis Bioaccumulation Long range transport Gas Chromatography – Mass spectrometry;

   Abstract : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. READ MORE

3. 7. Lifetime CostEffectiveness of Constructed Wetland and Rain Garden Facilities in Relation to Expected  Treatment Performance

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Abdullah Noorhussin Ali; [2023]
   Keywords : Stormwater; Total cost; StormTac; Cost-effectiveness;

   Abstract : The purpose of this thesis is to investigate the cost effectiveness of two different stormwater control measure (SCM) facilities, namely a constructed wetland in Boden and a rain garden in Gothenburg (both Sweden), in relation to treatment efficiency and contributing catchment area. The study approach involved collection of data, construction, and maintenance activities with their respective costs, for the two stormwater control measures from commercial and literature data.

5. 9. Detecting Pollutants Using Vibrations : Laser Doppler Vibrometry as a Non-Invasive Soil Organism Health Monitoring Method

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

   Author : Kristoffer Wilson; [2023]
   Keywords : Vibrometer; Biotremology; Imidacloprid; Ants;

   Abstract : Due to a lack of in-situ methods capable of detecting sub-lethal effects of pollutants on soil organisms, many polluted environments are not identified prior to pollution-induced changes in the soil fauna. Therefore, there is a need to develop new non-invasive methods to measure the health of soil organisms. READ MORE
