  1. 1. Isocyanates, Amines and Alkanolamines Sampling, Chromatography and Detection

    University dissertation from Stockholm : Department of Analytical Chemistry, Stockholm University

    Author : Jakob B. Riddar; Marianne Dalene; Gunnar Skarping; Daniel Karlsson; Håkan Westberg; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Air-sampling; Isocyanates; Aromatic amines; Aliphatic amines; Alkanolamines; Hydrophilic Interaction Liquid Chromatography; Dry Denuder-Filter sampler; Liquid Chromatography–tandem Mass Spectrometry; Polyurethane Foam Extraction; Analytical Chemistry; analytisk kemi;

    Abstract : Isocyanates, aromatic-, aliphatic- and alkanolamines are commonly used in the industry today. Millions of workers in Europe are exposed. The most frequent health symptoms are respiratory and dermal disorder. Due to the health risk most of the compounds in this thesis are regulated by authorities and have occupational exposure limits (OELs). READ MORE

  2. 2. Airborne Isocyanates, Aminoisocyanates and Amines

    University dissertation from Daniel Karlsson, Work Environment Chemistry, Lund University, Box 460, S-281 24, Hässleholm, Sweden

    Author : Daniel Karlsson; [2001]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Isocyanates - assessment of human exposure

    University dissertation from Division of Working Environment, Lunds Institute of Technology, S-221 00, Lund, Sweden

    Author : Håkan Tinnerberg; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Miljöteknik; kontroll av utsläpp; Analytical chemistry; Analytisk kemi; exposure; biomonitoring; occupational; isophorone diisocyanate; hexamethylene diisocyanate; methylenediphenyl diisocyanate; toluene diisocyanate; amines; aminoisocyanates; polyurethane; isocyanates; Liquid chromatography; Environmental technology; mass spectrometry;

    Abstract : Isocyanates are used mainly for manufacturing of polyurethane (PUR) foams, lacquers, elastomers and glues. The production of PUR exceeds 2 million tonnes per year and is increasing. Occupational exposure to isocyanates are associated with respiratory disorders. READ MORE

  4. 4. Isocyanates and Amines – Sampling and Analytical Procedures

    University dissertation from Stockholm : Institutionen för analytisk kemi

    Author : Åsa Marand; Gunnar Skarping; Marianne Dalene; Daniel Karlsson; Roy Rando; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isocyanates; Amines; Polyurethane; Air sampling; Industrial hygiene; Mass spectrometry; Liquid chromatography; Chemiluminescence; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi;

    Abstract : This thesis covers sampling and analytical procedures for isocyanates (R-NCO) and amines (R-NH2), two kinds of chemicals frequently used in association with the polymeric material polyurethane (PUR). Exposure to isocyanates may result in respiratory disorders and dermal sensitisation, and they are one of the main causes of occupational asthma. READ MORE

  5. 5. Biomarkers of aromatic isocyanates in exposed workers

    University dissertation from Divison of Occupational and Environmental Medicine and Psychiatric Epidemiology

    Author : Pernilla Lind; [1997]
    Keywords : 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;

    Abstract : 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. READ MORE
