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

    Magister-uppsats, Stockholms universitet/Institutionen för naturgeografi

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

    Sammanfattning : 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.

  3. 2. Pathways to resilient apple orchards –Economic and ecological aspects of Integrated Pest and Pollination Management

    Master-uppsats, Stockholms universitet/Stockholm Resilience Centre

    Författare :Anne Sophie Dietrich; [2022]
    Nyckelord :Integrated pest and pollination management; integrated economic-ecological modelling; resilient orchards; path dependenc;

    Sammanfattning : Apple orchards as social-ecological systems provide high value crops and habitat for a variety of species. Yields are influenced by pest control and pollination services, and profit-oriented management often motivates the use of inputs, e.g., pesticides, to complement or replace these services. LÄS MER

  4. 3. A molecular analysis of the interaction between the biocontrol fungus Clonostachys rosea and the cereal pathogen F. graminearum

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Esther Kuper; [2021]
    Nyckelord :Agrobacterium- mediated transformation; Biocontrol; Clonostachys rosea;

    Sammanfattning : Modern agriculture is increasingly challenged by newly emerging crop diseases- many of them caused by fungal pathogens. At the same time, excessive application of chemical fungicides accelerates the development of resistant pathogen strains and may cause harmful effects on non-target organisms. LÄS MER

  5. 4. Bekämpningsmedel för trädgårdar: utbudet i Lunds närområde och effekter på icke-målarter

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Elsa Welin; [2020]
    Nyckelord :Keywords: pesticides; plant protection products; non-target organisms; private gardens; home gardens; pyrethrin; acetamiprid; pelargonic acid Nyckelord: bekämpningsmedel; växtskyddsmedel; icke-målorganismer; icke-målarter; privata trädgårdar; hemträdgårdar; pyretrin; pelargonsyra; Earth and Environmental Sciences;

    Sammanfattning : Several studies show that the use of pesticides within agricultural management have led to increased losses of biodiversity. However, information on the effects of garden pesticides on non-target organisms and the type of products used in private gardens are lacking. LÄS MER

  7. 5. Effekter av psykofarmaka på planktonsamhällen - Experimentell pilotstudie.

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Rebecca Winberg; [2019]
    Nyckelord :ciliater; fluoxetin; grönalger; oxazepam; zooplankton;

    Sammanfattning : Till följd av samhällets konsumtion av psykofarmaka, återfinns rester av preparaten i utgående avloppsvatten som oförändrade eller i form av metaboliter. Avloppsvattnet utgör därför en betyd-ande källa till att vår akvatiska miljö exponeras för psykofarmaka, vars verkningsmekanismer på-verkar akvatiska organismsamhällens struktur och funktion. LÄS MER
