    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organophosphate esters; phthalate esters; air; dust; sampling; method development; GC MS; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Organophosphate and phthalate esters are polymer additives that are frequently found in air and dust in indoor environments. This thesis describes the development and application of air sampling and selective mass spectrometric (MS) determination of these two compound groups. LÄS MER

  4. 3. New methods for determination of airborne pollutants : Focus on tetrabromobisphenol A, organophosphate triesters and polycyclic aromatic hydrocarbons

    Författare :Johanna Tollbäck; Ulrika Nilsson; Peter Haglund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Air sampling; sampling methods; indoor air; SPE; SPME; extraction; dynamic extraction; online coupling; SWE; subcritical water extraction; GC MS; LC MS; organophosphate triesters; PAH; tetrabromobisphenol A; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : The work presented in this thesis concerns the development and evaluation of new methods of sampling and analysis of organic pollutants in the indoor and outdoor environment. In Paper I, the development of a new method was reported for the determination of the brominated flame retardant tetrabromobisphenol A (TBBPA) in air using sampling with glass fiber filter and polyurethane foam (PUF), ultrasonic solvent extraction and liquid chromatography coupled to electrospray ionisation mass spectrometry (LC-ESI/MS).

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human exposure; phthalates; organophosphates; plasticizers; flame retardants; modelling; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Phthalate esters (PEs) and organophosphate esters (OPEs) are common indoor pollutants frequently detected in environmental (dust, air), personal (hand wipes, diet) and human matrices (urine, serum etc.). LÄS MER

  7. 5. Levels and sources of organophosphorus flame retardants and plasticizers in indoor and outdoor environments

    Författare :Anneli Marklund; Peter Haglund; Barbro Andersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organophosphate esters; OPs; human exposure; air; dust; sewage treatment plants; sludge; oil; snow; deposition; flame retardants; plasticizers; analysis; TCEP; TPP; TCPP; TBP; TBEP; Environmental chemistry; Miljökemi;

    Sammanfattning : Global consumption of organophosphate esters (OPs), which are used as flame retardants and plasticizers, is rapidly increasing. Their use as additives in diverse applications poses a risk as they may be emitted from the products they are added to and be further transported in the environment. LÄS MER
