  1. 1. HgII uptake in Geobacter sulfurreducens spheroplasts : Thiols’ role in Hg partitioning and methylation

    University essay from Umeå universitet/Kemiska institutionen

    Author : Andreas Eriksson; [2021]
    Keywords : ;

    Abstract : Mercury (Hg) is a naturally occurring trace element and pollutant that is ubiquitous in aquatic ecosystems. All Hg species are hazardous, but methylmercury (MeHg) is the most alarming due to its neurotoxicity, teratogenicity, and bioaccumulation in the food web. READ MORE

  3. 2. Coumarin 47 and permethrin effects on zebrafish embryos: : FET tests and behavioural challenges

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Stefania Rabasco; [2018]
    Keywords : ;

    Abstract : An environment is defined as polluted when contaminants are introduced within it and causeadverse effects to its ecosystem. Chemical pollutants can migrate and often affect severalenvironmental compartments: for instance, chemicals can leach from polluted soil intogroundwater, or they can evaporate and disperse into the atmosphere.

  4. 3. Teratogenic and Embryotoxic Effects of Polycyclic Aromatic Compounds Report

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Svenja Wagner; [2016]
    Keywords : PACs; zebrafish; teratogenic; embryotoxic; toxicity;

    Abstract : Polycyclic aromatic compounds are ubiquitously distributed pollutants in the aquatic and terrestrial environment containing harmful properties on creatures such as carcinogenicity, teratogenicity and toxicity, but are not so well analyzed yet. In the present study, the embryotoxic and teratogenic effects of selected hydroxylated and methylated PACs on the embryonal development of Danio rerio as an aquatic model organism were analyzed with the Fish Embryo Toxicity Test (FET) and the Tail Length Test (TLT) to obtain information on the toxic and teratogenic impact of the tested PACs on the environment.

  5. 4. Miljögifters påverkan på delfiners hälsa och överlevnad : individ och populationsnivå

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Elvira Palmborg; [2016]
    Keywords : delfiner; miljögifter; PCB; DDT; PBDE; HCH; PFC; PAH; kadmium; kvicksilver; dolphins; environmental contaminants; cadmium;

    Abstract : Delfiner är utsatta för många antropogena hot, där en av dessa är miljögifter. Bioackumulering och biomagnifiering uppstår ofta på grund av delfinernas höga position i näringskedjan och miljögifternas persistens, vilket resulterar i höga nivåer av föroreningar i späck. Detta kan i sin tur leda till olika toxiska effekter. READ MORE

  6. 5. Vitamin A som orsak till gomspalt hos hund

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Emelie Torén; [2015]
    Keywords : gomspalt; gomutveckling; hund; vitamin A; retinol; retinoinsyra; teratogenicitet; cleft palate; palatogenesis; dog; canine; vitamin A; retinol; retinolic acid; teratogenicity;

    Abstract : Vitamin A och dess derivat har en avgörande funktion i kroppen, både hos dräktiga tikar och hos övriga hundar genom att påverka synförmåga och tillväxt av epitel samt andra viktiga cellulära mekanismer. För att fosterutvecklingen ska fungera normalt behöver moderdjuret få i sig tillräcklig mängd vitamin A via kosten. READ MORE
