1. 1. The impact of human relevant mixture of contaminants on the development of human adipocytes

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Annika Jansson; [2023]
   Keywords : ;

   Abstract : The objective of this project was to investigate how organic anthropogenic chemicals (OCs) effect the differentiation of adipocytes in the human body. The objective is also to contribute to novel research in how groups of chemicals in our surrounding affect us. READ MORE

3. 2. SINGLE AND COMBINED EXPOSURE OF POLYSTYRENE NANOPARTICLES AND NORTH SEA MARINE OIL IN TWO IN VITRO FISH MODELS

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Monica Olsson; [2022-10-05]
   Keywords : Polystyrene nanoparticles; crude oil; combined toxicity; cytotoxicity; oxidative stress;

   Abstract : The awareness of micro-and nanoplastic pollution and its impact on the marine ecosystem has increased over the last decade. Nanoplastics may affect aquatic organisms since their small size and high surface-to-volume ratio increases their bioavailability and ability to cross biological membranes. READ MORE

4. 3. INVESTIGATING THE TOXIC AND ACIDIFYING EFFECT OF SCRUBBER EFFLUENT ON STRONGYLOCENTROTUS DROEBACHIENSIS LARVAE

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Ida Vartia; [2022-09-28]
   Keywords : ;

   Abstract : To meet the new environmental requirements of reduced sulfur emissions from ships, many shipowners have installed an open-loop scrubber to clean the exhaust. In this scrubbing process, seawater is pumped from the ocean and combined with the emission gas, creating an acidic and toxic effluent that is directly discharged into the ocean, potentially damaging the marine environment.

5. 4. 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.

6. 5. Photo-physical properties of up-converting NaYF4:Yb-Er,Yb-Mn nanocrystals

   University essay from KTH/Tillämpad fysik

   Author : Hongjian Wu; [2022]
   Keywords : Appled Physics; Tillämpad fysik;

   Abstract : Rare earth-doped upconversion nanoparticles can emit light with various wavelength from ultraviolet to infrared when excited by near-infrared light. The superior properties including long luminescence lifetime, narrow emission spectra, low toxicity and high chemical stability makes it a promising optical material in bioimaging and other applications.
