  2. 1. A Novel Miniaturised Dynamic Hollow-Fibre Liquid-Phase Micro-Extraction Method for Xenobiotics in Human Plasma Samples

    Author : Helena Hansson; Ulrika Nilsson; Bo Karlberg; Peter Haglund; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sample clean-up; human blood plasma; hollow-fibre liquid phase microextraction; supported liquid membrane extraction; SLM; HF-LPME; sample preparation; bioanalysis; liquid-liquid extraction; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Bioanalytical chemistry is a challenging field, often involving complex samples, such as blood, plasma, serum or urine. In many applications, sample cleanup is the most demanding and time-consuming step. READ MORE

  4. 2. Uptake and bioaccumulation of ionizable pharmaceuticals in aquatic organisms

    Author : Marja L. Boström; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antidepressiva medel; Avloppsvatten; BAF; BCF; Bioackumulation; Biokoncentration; Biomagnifikation; CYP; Extraktionsteknik; HF-LPME; Joniserbara läkemedel; Metabolism; pH; Riskanalys; Tolerans; Antidepressant; BAF; BCF; Bioaccumulation; Bioconcentration; Biomagnification; CYP; Extraction technique; HF-LPME; Ionizable pharmaceutical; Metabolism; pH; Risk assessment; Tolerance; Wastewater;

    Abstract : Pharmaceuticals are found at low concentrations (ng/L) in aquatic environments but bioaccumulation may result in aquatic organisms reaching internal effect levels (µg/L). Environmental hazard assessments include standardized bioaccumulation tests but contrary to the model substances around which the frameworks are built most pharmaceuticals are designed to mimic endogenic chemicals, ionizable, and less lipophilic.

  5. 3. Analysis of tracer molecules from organic aerosols - Application of liquid phase microextraction to aerosol analysis

    Author : Murtaza Hyder; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Liquid membrane extraction; Secondary organic aerosols; Enrichment; Tracers; Hollow fiber liquid phase microextraction; Biomass burning; Organic carbon;

    Abstract : Airborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes. In order to understand completely the role of aerosols in atmosphere, their chemical composition is of basic importance. READ MORE
