Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE

  3. 13. Ecological risk assessment of pesticide use in rice farming in the Mekong Delta , Vietnam

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Bubaraye Ohiosimuan Dirikumo; [2023]
    Keywords : Pesticides; Ecological Risk Assessment ERA ; rice farming; Mekong Delta; PRIMET Model; Exposure Toxicity Ratio ETR ; species sensitivity distribution SSD ; predicted environmental concentrations PECs ;

    Abstract : Pesticide use in rice farming is a common practice in the Mekong Delta and poses ecological risks to aquatic organisms, the environment, and human health. This study focused on the ecological risk assessment of pesticide use in rice farming using the PRIMET model as a decision support tool to evaluate the risks of pesticide exposure, ecotoxicity, and risk characterization, as well as employing the species sensitivity distribution (SSD) assessment model to calculate the potentially affected fraction (PAF) of species based on the computed predicted environmental concentrations (PECs) from PRIMET.

    Abstract : Tanzania is a country located in sub-Sahara Africa by the Indian Ocean. Tanzania's aquaculture sector is small but has the potential to grow. As the population grows, so does the demand for food. Nile tilapia is the most cultured fish in Tanzania due to its hardiness, fast growth and tolerance to many environmental conditions. READ MORE

  5. 15. Formellt skyddad mark och riksintressen i närområde till landbaserad vindkraft i Sverige

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Erika Åmansson; [2023]
    Keywords : landbaserad vindkraft; formella skydd; riksintressen; relativ täthet; markanvändningskonflikter;

    Abstract : Klimat- och energiomställningen i världen är det som driver dagens utbyggnation av vindkraft, som betraktas som en fossilfri, förnyelsebar och ren energikälla. I och med utökningen av vindkraft berörs även många andra intressen och värden som överlappar med områden som ianspråktas för vindkraft eller finns i dess närhet och därmed kan komma att skapa konflikter.
