  1. 41. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Oscar R. Davies; [2022]
    Nyckelord :Hjältevad; zerovalent iron; phosphate extraction; Oxalate extraction; Visual MINTEQ; geochemical modelling;

    Sammanfattning : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. LÄS MER

  2. 42. Analysis of DNA methylation changes and behavioural outcomes in adulthood induced by prenatal exposure to a mixture of endocrine disrupting chemicals

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Shane Kamil; [2022]
    Nyckelord :Toxicology; Developmental biology; Epigenetics; Genetics; Methylation; EDC; Toxins; Chemicals; Mixture effect; Mediation; Toxikologi; Utvecklingsbiologi; Epigenetik; Genetik; Metylering; Miljögifter;

    Sammanfattning : Endocrine disrupting chemicals, or EDCs, are some of the most prevalent toxic chemicals found in the environment because of human activity and they have a variety of adverse effects on both humans and wildlife. A proposed mechanism through which EDCs can negatively affect an organism is via an epigenetic mechanism known as DNA methylation, which can affect the development of the organism with negative outcomes later in life.

  3. 43. Dioxin i mark : En undersökning kring saneringsmetoder in-situ och on-site.

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

    Författare :Anton Axelsson; [2022]
    Nyckelord :Dioxin in soil; Dioxin i mark;

    Sammanfattning : Dioxins are among the most toxic substances known to man. Dioxins are hydrophobic organic molecules that accumulate in the food chain and can cause cancer and reproductive difficulties for both animals and humans. A common method for remediating contaminated soil is excavation and transporting the masses to a landfill site. LÄS MER

    Sammanfattning : Out of the 17 Sustainable Development Goals (SDGs) adopted by the United Nations in 2015, chemicals and waste management are obtainable under six. Improper and unsafe disposal of toxic chemicals into the environment affects life below water (SDG 14), human health and well-being (SDG 7), and clean water and sanitation (SDG 6). LÄS MER

  5. 45. Development and evaluation of an IoT network for sensing

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap
