  2. 1. Mercury species transformations in marine and biological systems studied by isotope dilution mass spectrometry and stable isotope tracers

    Author : Lars Lambertsson; Wolfgang Frech; John Munthe; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Mercury; methylmercury; ethylmercury; Thimerosal; speciation; methylation; demethylation; brackish water sediment; natural waters; GC-ICP-MS; species-specific isotope dilution; isotope enriched tracers; Analytisk kemi; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Abstract : This thesis focuses on the implementation of species-specific isotope dilution (SSID) methodology and stable isotope tracers to determine mercury species occurrence and transformation processes in-situ and during sample treatment. Isotope enriched tracers of methyl-, ethyl- and inorganic mercury were synthesised and applied in different combinations to marine and biological samples. READ MORE

  4. 2. On the reliability of methods for the speciation of mercury based on chromatographic separation coupled to atomic spectrometric detection

    Author : Johanna Qvarnström; Umeå universitet; []
