  1. 1. BSF-colony management efficiency at a large scale fly larvae composting company in Kenya – A field study

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hilda Anderberg; [2023]
    Keywords : Black soldier fly composting; BSF-colony; industrial scale; parasitic wasps; Amerikansk vapenfluga; fluglarvskompostering; storskaligt; parasitsteklar;

    Abstract : The majority of organic waste globally is either dumped or placed on landfills, which can result in spreading of disease and pests, methane gas emissions, the deterioration of landscapes and odour pollution. One of the solutions to poor organic waste management is to create value from waste. READ MORE

  3. 2. Biocatalysis in Pickering emulsions

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Christine Vera Isabel Schmidt; [2023]
    Keywords : Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Abstract : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. READ MORE

  4. 3. Effekten av PCB126 in vitro på tidig embryonalutveckling hos nötkreatur

    University essay from SLU/Dept. of Clinical Sciences

    Author : Erik Oscar Eriksson; [2020]
    Keywords : nötkreatur; bovin; embryoutveckling; in vitro; IVF; IVP; IVM; PCB; PCB 126; polyklorerade bifenyler;

    Abstract : Polyklorerade bifenyler (PCB) är industrikemikalier som började framställas i stora mängder under 1930-talet. Kommersiellt har PCB varit tillgängligt som komplexa kemiska blandningar i bland annat bekämpningsmedel, färg, plaster och olika elektriska komponenter. PCB är en grupp av över 200 dioxin- eller icke dioxinlika klorerade kolväten. READ MORE

  5. 4. Perfluorooctane sulfonate (PFOS) and related chemicals in eggs from Sweden and China

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Yasmin Karimi; [2019]
    Keywords : PFOS; PFOA; Chicken Egg; LC-MS MS; Organic egg; Conventional egg;

    Abstract : Dietary intake is one of the major routes of human exposure to perfluoroalkyl and/or polyfluoroalkyl substances (PFAS). The objective of this study was to measure perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonic acid (PFHxS) in organic and conventional egg from Sweden (n=8, consisted of 4 pooled eggs and 4 individuals) and China (n=9, consisted of 4 pooled eggs and 5 individuals) and compare the concentrations of PFAS between the two categories (organic and conventional).

  6. 5. Trace level analyses of selected perfluoroalkyl substancesin food: Method development and validation

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Mohammad Sadia; [2019]
    Keywords : ;

    Abstract : To comprise the future requirements to detect low levels of perfluoroalkane acids, includingbranched and linear perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA),and perfluorohexane sulfonic acid (PFHxS) in food items, here analytical methods fordetermination of PFOS, PFOA and PFHxS in six different food matrices (cow milk, butter,chicken egg, chicken meat, beef, and fish) were optimized and validated. The optimizedmethod was based on alkaline digestion and solid-liquid extraction using acetonitrile,followed by solid phase extraction (SPE) using a weak anion exchange cartridge as clean-up. READ MORE
