  1. 1. EFFECT OF ENDOCRINE DISRUPTING MIXTURES AND CHEMICALS ON THE OXYGEN CONSUMPTION RATE OF ZEBRAFISH LARVAE

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Lieke van Iersel; [2022-08-08]
    Keywords : oxygen consumption; zebrafish larvae; respirometry; endocrine disrupting chemicals; mixture toxicity;

    Abstract : Chemicals affecting the endocrine system, so called endocrine disrupting chemicals (EDC’s), have been steadily increasing in the environment over the last 40 years. EDCs are harmful chemicals since they can act through multiple endocrine pathways, contain a wide spectrum of health effects that can be very persistent and can cause effects already at a low doses.

  6. 5. The study of organofluorine analysis applied to totaloxidizable precursor (TOP) assay to understand perandpolyfluoroalkyl substances (PFASs)

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Crystal Ho; [2018]
    Keywords : Poly- per-fluoroalkyl substances; total oxidizable precursor TOP assay; AFFFs; combustion ion chromatography; oxidation;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are synthetic chemicals which are used in a wide range of applications such as aqueous film forming foam (AFFF) for firefighting, paint, coating and cosmetics. For almost a decade, PFASs have received worldwide attention because of the ubiquitous detection of PFAS in the environment and their bioaccumulative, persistent and give toxic effects on animals and humans.
