1. 1. Temporal trends of 4-Hydroxychlorothalonil in maternal serum samples, 1997-2015

   University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Author : Elin Wällstedt; [2023]
   Keywords : Biomonitoring; human exposure effects; environmental exposure; fungicide; pregnancy; pregnant women; chlorothalonil; CHT; 4-hydroxy-chlorothalonil; 4-OH-CHT; Earth and Environmental Sciences;

   Abstract : Agricultural fungicides are extensively used for infestation control, resulting in residues of these compounds in food. Human exposure to environmental contaminants might occur via different routes, such as inhalation, skin contact, or ingestion. Exposure to several pesticides has been associated with adverse human health outcomes. READ MORE

3. 2. A Comparative Analysis of Per- andPolyfluoroalkyl Substances (PFAS) and ExtractableOrganofluorine (EOF) Using Solid PhaseExtraction-Weak Anion Exchange and Ion PairExtraction in SerumMarichal SalamehSpring 2021Independent project

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Marichal Salameh; [2021]
   Keywords : Extractable organofluorine EOF ; Per- and polyfluoroalkyl substances PFAS ; horse serum; human serum; ion pair extraction IPE ; solid phase extraction - weak anion exchange SPE-WAX ; liquid chromatography tandem mass spectrometry LC-MS MS ; combustion ion chromatography CIC ;

   Abstract : Per- and polyfluorinated substances (PFAS) are compounds that consist of a carbon chainbackbone that is partially or entirely fluorinated, with an addition of a functional group. SomePFAS are known as persistent organic pollutants (POPs) and have therefore been drawing a lot ofattention as well as increased concerns. READ MORE

4. 3. Fjädermyggspopulationer i Skandinaviska sjöar : övervakningsmetoder längs en eutrofieringsgradient

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Bella Strid; [2021]
   Keywords : fjädermygglarv; miljöövervakning; BQI;

   Abstract : Fjädermyggs akvatiska larver har sedan hundra år tillbaka använts i övervakning av miljön tack vare sin stora artvariation och känslighet för omgivningen. Ett av världens mest använda index för att bedöma en sjös ekologiska status är Benthic Quality Index (BQI) som ämnar kategorisera sjöar till en av fem nivåer (dålig till hög), vilket ska spegla hur miljön mår i sjöns tillrinningsområde.

5. 4. Method Development for Sample Preparation of Fish for Non-target Analysis of Hydrophobic Organic Pollutants

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Bergdís Björk Bæringsdóttir; [2020]
   Keywords : ;

   Abstract : Monitoring methods for environmental pollutants are mostly performed with targeted analysis which relies on predetermined compounds. This can cause an underestimation of possible toxicants as it might not detect undiscovered compounds such as breakdown products of other chemicals. READ MORE

6. 5. Copper bioaccumulation in blue mussels and periwinkles from marinas

   University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Author : Tomas Sjökvist; [2019]
   Keywords : Littorina littorea; Mytilus edulis; antifouling paint; invertebrates; biomonitoring;

   Abstract : Copper (Cu) is a heavy metal that is essential for life but toxic at high concentrations. This toxic effect is used on boats to prevent biofouling on boat hulls by painting the hulls with antifouling paint that contain high levels of Cu. The Cu is slowly diffused out in the water and accumulated by animals higher up in the food chain. READ MORE
