1. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. LÄS MER
2. In Situ and Ex Situ Study of Nanoparticles Stability and Transformation in Simulated Aquatic Natural Media
Kandidat-uppsats, KTH/KemiSammanfattning : Nanopartiklar är partiklar med storlekar i området 1 till 100 nm, och som uppvisar nanospecifika egenskaper. Egenskaperna kan variera helt mellan olika typer av nanopartiklar, även bland partiklarna och deras respektive material i bulk format på grund av deras unika storlekar, former och strukturer. LÄS MER
3. Kadmiumhalter i svensk tång
Kandidat-uppsats, Lunds universitet/Livsmedelsteknik (kandidat); Lunds universitet/Livsmedelteknisk högskoleutbildning - YTHSammanfattning : Seaweed along the Swedish coast contains both proteins, fats, vitamins and minerals, and could be part of the food supply of the future. It could also be described as climate smart as seaweed does not need to be watered, fertilized, or take up land for cultivation. LÄS MER
4. Recovery of Cobalt and Copper from Zambia Slag via Sulphidisation with Gypsum
Master-uppsats, KTH/MaterialvetenskapSammanfattning : The main objective of this research was to recover copper and cobalt from slags coming from copper processing on the Copperbelt province of Zambia. Pyrometallurgical processing of copper sulphide concentrate generates huge tonnes of slag wastes. LÄS MER
5. Bioackumulering av tungmetaller i vildsvin (Sus scrofa) : -analys av biotillgängligheten av bly och kadmium i vildsvinslever
M1-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskapSammanfattning : As the wild boar population increases, so does the consuming of wild boar meat. Often with the belief that this is much healthier than conventional meat. International studies have shown that wild boar meat is more likely to contain higher concentrations of soil pollutions than other game meat. LÄS MER
