  1. 1. Novel Technique for Analysing Volatile Compounds in Indoor Dust : Application of Gas Chromatography – UV Spectrometry to the Study of Building-Related Illness

    Författare :Anders Nilsson; Christer Tagesson; Verner Lagesson; Göran Strid; Linköpings universitet; []
    Nyckelord :acrylates adverse effects; air pollution; ultraviolet; indoor analysis; chromatography; gas; environmental exposure adverse effects; sick building syndrome etiology; dust; volatilization; Spectrophotometry; MEDICINE; MEDICIN;

    Sammanfattning : It is now generally acknowledged that particulate air pollution can cause respiratory symptoms and that indoor dust particles may be associated with mucous membrane irritation and odour annoyance. One reason for this may be that dust particles adsorb large quantities of gases and other volatile compounds. LÄS MER

  3. 2. Mycotoxins in indoor environments. Determination using mass spectrometry

    Författare :Erica Bloom; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas chromatography; Mass spectrometry; Mycotoxin; Indoor Air; Ergosterol.; Mold; High pressure liquid chromatography; Dust; Building materials;

    Sammanfattning : Dampness in indoor environments may cause various health problems. The specific causative agent(s) are unknown but may originate from degradation processes in damp materials, microbial growth, or a combination of these phenomena. The health impact of dampness in buildings is a politically, legally, and economically important question. LÄS MER

  4. 3. Brominated flame retardants and perfluoroalkyl acids in Swedish indoor microenvironments : Implications for human exposure

    Författare :Justina Björklund; Cynthia de Wit; Thomas Webster; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PBDEs; HBCD; PFOS; PFOA; indoor air; indoor dust; breast milk; human exposure; emission; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Humans are exposed to persistent organic pollutants (POPs) such as brominated flame retardants (BFRs, specifically polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)) and perfluoroalkyl acids (PFAAs, specifically perfluoroalkane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)). They are used in consumer products found in cars, offices, homes and day care centers. LÄS MER

  5. 4. Organophosphates and phthalates in air and dust from indoor environments : Method development and applied measurements

    Författare :Caroline Bergh; Conny Östman; Peter Haglund; Stockholms universitet; []
    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

  7. 5. The indoor environment in schools : Respiratory effects and air quality

    Författare :Greta Smedje; Uppsala universitet; []
    Nyckelord :Medical sciences; Allergy; asthma; cat allergen; cleaning; dust; formaldehyde; furniture; mould; schoolchildren; ventilation; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : The main objective of this work was to investigate relationships between the schoolenvironment and asthma and asthmatic symptoms in schoolchildren. Data on symptoms werecollected through postal questionnaires answered by 1,732 pupils in 39 randomly selectedschools, and were related to data on exposures obtained through hygienic measurements in theschools.
