  1. 1. Airborne Isocyanates, Aminoisocyanates and Amines

    Författare :Daniel Karlsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental health; Miljökemi; Environmental chemistry; amines; aminoisocyanates; isocyanates; polyurethane; exposure; occupational; thermal degradation; chemiluminescence; mass spectrometry; Liquid chromatography; gas chromatography; Miljömedicin; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : Isocyanates are used in the production of polyurethane (PUR). Exposure to isocyanates is associated with respiratory disorders and may occur during production or processing of PUR. During thermal degradation of PUR, amines and aminoisocyanates are formed in addition to isocyanates. LÄS MER

  3. 2. Biological and air monitoring of exposure to isocyanates

    Författare :Carl Johan Sennbro; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; industrial medicine; Occupational health; asthma; protein adducts; polyurethane; biomarkers; occupational exposure; DBA; ICA; NDI; MDI; TDI; Diisocyanates; Isocyanates; Biomonitoring; Air monitoring; arbetsmiljömedicin; Yrkesmedicin;

    Sammanfattning : Exposure to isocyanates may induce disorders in the airways of workers. Therefore, application, development and validation of methods for exposure assessment is of great importance. LÄS MER

  4. 3. Chemical and Clinical Studies of Isocyanate Contact Allergy with focus on diphenylmethane diisocyanate

    Författare :Malin Engfeldt; Yrkes- och miljödermatologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; venereologi; Dermatologi; venereology; Dermatology; occupational; allergic contact dermatitis; polyurethane;

    Sammanfattning : Isocyanates are highly reactive compounds used in the production of polyurethane. Exposure to isocyanates is mainly associated with respiratory disorders, but may also result in allergic contact dermatitis. Reports describing contact allergy to isocyanates are few in number and it has been considered a rare phenomenon. LÄS MER

  5. 4. Biomarkers of aromatic isocyanates in exposed workers

    Författare :Pernilla Lind; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adducts; biomarkers; exposure; occupational; methylenediphenyl diisocyanate; toluene diisocyanate; amines; isocyanates; polyurethane; Gas chromatography; mass spectrometry; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : The aromatic isocyanates, toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), are used in the production of polyurethane (PUR) foams, paints, elastomers and glues. The use of isocyanates is increasing, and exposure to isocyanates is the most common cause of occupational asthma. LÄS MER

  7. 5. Polyurethane - occupational exposure, biomarkers and symptoms

    Författare :Margareta Littorin; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spray; polyurethane; nose; metabolites; lung function ; lower airways; inflammation; heat; glue; genetic polymorphism; di isocyanate; Antibodies; biomarkers; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin; symptoms;

    Sammanfattning : Isocyanates may cause occupational asthma, rhinitis, and hypersensitivity pneumonitis. However, the mechanisms behind initiation of the disorders and the relations between exposure and effect are insufficiently elucidated. Means to biomonitor exposure and risk would be valuable. LÄS MER
