Project: Exposure assessment of water and food pollutants in Sweden
Because the main sources of exposure to toxic metals are drinking water and food, we have measured multiple metals and other trace elements in breast milk and infant and child foods. Also, in collaboration with SGU, we have measured multiple elements in Swedish wells. An important part of our research is to develop biomarkers of different exposures in various population groups. We have a well-equipped, modern laboratory (clean-room with HEPA filter) with two ICP-MS instruments and an UltraClave microwave digestion system. The Agilent 7700x ICP-MS (Agilent Technologies, Tokyo) is used for multi-element analysis and includes a High Matrix Introduction kit (HMI) and an Octopole Reaction System (ORS3, removes polyatomic interferences). The 7700x system allows simultaneous high-throughput measurement of multiple elements down to ppt levels with a nine orders dynamic range. The Agilent 7500ce ICP-MS is used as on-line detector for HPLC separation of inorganic and organic arsenic metabolites in human urine.
