1. 21. Biochar and hemp as peat substitutes in organic growing media : effects on nutrient availability and nutrient uptake

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Malin Nilsson; [2022]
   Keywords : Growing media; substrate; biochar; hemp; peat substitution; nutrient availability; nutrient use efficiency;

   Abstract : This study aimed at evaluating the suitability of biochar and hemp as partial or complete replacement of peat in horticultural growing media, with specific emphasis on the effects on nutrient availability and plant nutrient uptake. The study was motivated by the environmental concerns surrounding the use of peat, along with a desire to explore possible uses for biochar and a crop residue from hemp cultivation. READ MORE

3. 22. Toxicological analysis of Pyraclostrobin and Cyprodinilon Zebrafish larvae

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Kim Yeju; [2022]
   Keywords : gene expression; mixture effect; toxicity; pesticides; stress response;

   Abstract : Cyprodinil and pyraclostrobin are widely used pesticides to protect many plants from attack of microorganisms and fungal diseases. Although cyprodinil and pyraclostrobin exist in the aquatic environment at low concentration, their leftovers in the ecosystems lead to oxidative damage and interfere development in aquatic animals at environmental-relevant concentration.

4. 23. Room for residential solar PV?: Exploring the socio-technical system narratives and barriers of the residential solar PV diffusion in Thailand.

   University essay from Lunds universitet/Internationella miljöinstitutet

   Author : Sawinee Galaputh; [2022]
   Keywords : Socio-technical systems; solar photovoltaics; adoption barriers; community solar; Earth and Environmental Sciences;

   Abstract : In working to reduce this increasingly intensified effect of climate change, one of the key strategies employed by different countries around the world is to reduce Green House Gas (GHG) emissions from the energy sector. As they are one of the biggest contributors, the strategies include the employment of different mitigation actions and fading away from the conventional fossil fuel source to a more renewable source of energy production.

5. 24. Nutrient Retention in Constructed Wetlands

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Johanna Kero; [2022]
   Keywords : Constructed wetlands; nutrient retention; phosphorus; nitrogen; catchment area factors; Anlagda våtmarker; näringsretention; fosfor; kväve; avrinningsområdesfaktorer;

   Abstract : Eutrophication, a surplus of nutrients, is a problem in aquatic environments and one of the Swedish Environmental Goals is that there should be no eutrophication caused by human activities. Constructed wetlands (CW:s) is a measure that could be implemented to decrease the transport of nutrients to water bodies through retention. READ MORE

6. 25. Removal Characteristics of Fibrous and Particulate Microplastics : A Study of the Effectiveness of Coagulation-Flocculation- Sedimentation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Amrith Kumar; [2022]
   Keywords : Coagulation; flocculation; jar test; microplastics; sedimentation; water treatment; Burktest; flockning; koagulering; mikroplaster; sedimentering; vattenrening;

   Abstract : The rapid proliferation of microplastics (MPs) over the last few decades have raised alarms about the major environmental and health impacts posed by this anthropogenic source. The widespread propagation and transport of MP particles in water sources have accelerated the need to study the eco- toxicological impacts as well as the efficacy of various removal mechanisms from these critical water sources.
