  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. Investor preferences reflected in sustainability reporting A study assessing the informational quality of sustainability reports with respect to investor preferences Bachelor's

    Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

    Författare :Filip Carlsson; Simon Anderberg; [2021-06-30]
    Nyckelord :Sustainability reporting; Greenwashing; Screening; ESG; CSR; ERA; Asymmetries; communication.;

    Sammanfattning : The interest for investing in sustainable assets has grown rapidly over the recent years. Many investors use methods for risk assessment based on for example Environmental, Social and Governance (ESG), Corporate Sustainability (CS), Environmental Risk assessment (ERA) and Socially Responsible Investments (SRI).

  4. 3. Comparison of two methods in deriving aquatic predicted no-effect concentration (PNEC) for α-Amylcinnamaldehyde, 1-Tridecanol and Paracetamol

    Magister-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Emma Holmén; [2019]
    Nyckelord :PNEC; Environmental risk assessment; ERA; α-Amylcinnamaldehyde; 1- tridecanol; paracetamol; Species Sensitivity Distributions; SSD; ECHA; Guidance on information requirements and chemical safety assessment; Earth and Environmental Sciences;

    Sammanfattning : This study is evaluating two methods in order to calculate predicted no effect concentrations (PNECs) used in environmental risk assessment for three chemicals (α-Amylcinnamaldehyde, 1-tridecanol and paracetamol). The methods used are Species Sensitivity Distributions (SSD) and the guideline from European Chemicals Agency (ECHA): “Guidance on information requirements and chemical safety assessment”. LÄS MER

  5. 4. Occurrence and Risk Assessment of Illicit Drugs in Wastewater Treatment Plants’ influent and effluent in Halland County, Sweden: Cocaine, MDMA, Amphetamine, Methamphetamine, and Cannabis.

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Jamshid Ansari; [2018]
    Nyckelord :Drugs of abuse; Environmental Risk Assessment ERA ; Predicted No Effect Concentration PNEC ; Sewage Treatment Plants STPs ; ECOSAR;

    Sammanfattning : Recently, the presence of illicit drugs in effluents from Wastewater Treatment Plants (WWTPs) and the aquatic environment has raised concern over their possible negative effects on aquatic organisms. In this study, therefore ecotoxicological data was retrieved through a literature survey and by using the software ECOSAR. LÄS MER

  7. 5. Jämförande livscykelanalys av motsvarande tegel- och träkonstruktioner

    M1-uppsats, KTH/Byggteknik och design

    Författare :Tomas Viborg; Gabriel Lidström; [2014]
    Nyckelord :Life Cycle Assessment; vanal wall; anavitor; brick structure; timber structure; LCA; livscykelanalys; kanalmur; anavitor; tegelkonstruktion; träkonstruktion; typhus; LCA;

    Sammanfattning : Sedan 1900-talets mitt har användandet av tegelkonstruktioner i bostadsbyggandet minskat kraftigt; materialet har under modernismen upplevts otidsenligt och byggnadssättet har ansetts ineffektivt. Trots att kanalmurstekniken, som är en byggteknik med bärande tegelkonstruktion och högt isoleringsvärde, togs fram på 1930-talet för att följa hårdare energihushållningskrav, har ändå lätta träregelkonstruktioner dominerat det svenska småhusbyggandet.
