  1. 1. Assessment of human exposure to per- and polyfluorinated compounds (PFCs) : exposure through food, drinking water, house dust and indoor air

    University dissertation from Örebro : Örebro universitet

    Author : Ingrid Ericson Jogsten; Örebro universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human exposure; per- and polyfluorinated compunds PFCs ; dietary intake; drinking water; indoor environment; TECHNOLOGY; TEKNIKVETENSKAP; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Miljökemi; Environmental Chemistry; Kemi; Chemistry;

    Abstract : Per- and polyfluorinated compounds (PFCs) are detected in humans worldwide but all sources of human exposure have not been fully characterized. The aim of this thesis was to evaluate the contributions from food, water, air and dust as sources for human PFC exposure in the general population. READ MORE
