1. 6. Isocyanates and Amines – Sampling and Analytical Procedures

   Författare :Åsa Marand; Gunnar Skarping; Marianne Dalene; Daniel Karlsson; Roy Rando; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Isocyanates; Amines; Polyurethane; Air sampling; Industrial hygiene; Mass spectrometry; Liquid chromatography; Chemiluminescence; Analytical chemistry; Analytisk kemi;

   Sammanfattning : 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. LÄS MER

3. 7. Isocyanates, Amines and Alkanolamines : Sampling, Chromatography and Detection

   Författare :Jakob B. Riddar; Marianne Dalene; Gunnar Skarping; Daniel Karlsson; Håkan Westberg; Stockholms universitet; []
   Nyckelord :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;

   Sammanfattning : 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). LÄS MER
