1. Yearly distribution and composition of per- and polyfluoroalkyl substances (PFAS) in Luleå wastewater treatment plant
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : PFAS (per- and polyfluoroalkyl substances) are a large group of substances that are used in a large variety of products because of their unique water and dirt repellent properties. The substances are extremely persistent and can spread over large distances in groundwater, surface water, and in the air, which makes them an environmental and a health concern. READ MORE

3. A Toxic Legacy? : A Study of PFAS Leakage from Landfills in the Eastern Part of Mälaren
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : The growing concern around per- and polyfluoroalkyl substances (PFAS) and their negative health and environmental effects have lately become more apparent which also is reflected in the new, more strict regulations of permitted levels of PFAS in drinking water extracted from water resources. However, many point sources of PFAS pollution to the environment and to water resources are still not identified and assessed for risk. READ MORE

5. Hydrological modelling of a recycling facility and landfill
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : A parsimonious lumped model for simulating a catchment composed of a landfill and recycling facility were developed. The modelling results showed an acceptable conformity with the observed values with NSE of 0.54 and R2 of 0.56 in hourly simulations, though the results were characterized by a general underestimation.
