  1. 1. How to estimate environmental persistence Understanding persistence of organic micropollutants in rivers from a multidisciplinary perspective

    Detta är en avhandling från Stockholm : Department of Environmental Science, Stockholm University

    Författare :Claudia Coll Mora; Anna Sobek; Matthew MacLeod; Emma J. Rosi; [2020]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic micropollutants; biodegradation; persistence; rivers; flume mesocosms; Junge relationships; OECD 308 bottle incubations; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Organic micropollutants such as food additives, pharmaceuticals and personal care products are found in rivers worldwide. Persistence is a key criteria in chemical risk assessment as micropollutants that are persistent pose an exposure hazard to humans and the environment. LÄS MER

  4. 4. Objects in Time : Studies of Persistence in B-time

    Detta är en avhandling från Department of Philosophy, Lund University

    Författare :Tobias Hansson Wahlberg; [2009]
    Nyckelord :HUMANIORA; HUMANITIES; B-time; three-dimensionalism.; stage theory; tenselessness; persistence; perdurance; mereology; four-dimensionalism; dispositions; endurance; B-theory of time; change; temporary intrinsics;

    Sammanfattning : This thesis is about the conceptualization of persistence of physical, middle-sized objects within the theoretical framework of the revisionary ‘B-theory’ of time. According to the B-theory, time does not flow, but is an extended and inherently directed fourth dimension along which the history of the universe is ‘laid out’ once and for all. LÄS MER

  5. 5. Partitioning and persistence of volatile methylsiloxanes in aquatic environments

    Detta är en avhandling från Department of Philosophy, Lund University

    Författare :Dimitrios Panagopoulos; Matthew MacLeod; Annika Jahnke; Amelie Kierkegaard; Whelan Mick; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; siloxanes; organic carbon; sediment; partitioning; persistence; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The presence of volatile methylsiloxanes (VMS) in the environment has raised concerns among environmental chemists and regulators about their persistence and the risks they may pose to the environment. This thesis explores the partitioning and persistence of VMS in aquatic environments. LÄS MER
