2. 1. Recycling Filter Substrates used for Phosphorus Removal from Wastewater as Soil Amendments

   Author : Victor Cucarella Cabañas; Gunno Renman; Greg Morrison; KTH; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Compact filter; Filtra P; Phosphorus recycling; Polonite; Soil amendment; Sorption isotherms; Soil science; Markvetenskap; Solution chemistry; Lösningskemi; Agricultural engineering; Jordbruksteknik; Water engineering; Vattenteknik; Environmental chemistry; Miljökemi;

   Abstract : This thesis studied the viability of recycling filter substrates as soil amendments after being used in on-site systems for phosphorus (P) removal from wastewater. Focus was put on the materials Filtra P and Polonite, which are commercial products used in compact filters in Sweden. READ MORE

4. 2. Influence of water conditions on growth and mineral nutrient uptake of native plants on clacareous soil

   Author : Aparna Misra; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; agricultural hydrology; Lantbrukshydrologi; marklära; Växtekologi; Plant ecology; wet growing; wet dry cycles; soil solution; soil moisture; pH; nutrient poor soil; mineral nutrients; dry growing; Bicarbonate; calicole; Soil Science;

   Abstract : The studies presented in Papers I to IV illustrate the importance of soil moisture in soil solution chemistry and response of native plants to the changes induced by change in moisture regime. With the help of glasshouse experiments I tried to study the influence of different treatments of soil moisture conditions on the mineral uptake by native plants of calcareous soil. READ MORE

7. 5. Binding of per- and polyfluoroalkyl substances (PFASs) in soil : effects of solution chemistry, soil properties, and PFAS structure

   Author : Hugo de Campos Pereira; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The large environmental mobility and persistence of per- and polyfluoroalkyl substances (PFASs) along with confirmed or suspected toxicities make the substances one of the great challenges of our time in the fields of chemical management and environmental risk assessment. In order to risk assess PFAS-contaminated sites, improved quantitative and mechanistic understanding of the partitioning and retention in soil is crucial. READ MORE
