2. 1. Chemical exposures, biological monitoring and cancer risks in Swedish aluminium foundries and remelting plants

   Author : Håkan Westberg; Hans Welinder; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : In aluminium foundries and remelting plants, a wide range of chemical agents are formed and emitted, including some highly toxic organochlorine compounds. This thesis explores emissions and exposures, as well as worker risk of porphyria and cancer. READ MORE

4. 2. Quartz in Swedish iron foundries : exposure and cancer risk

   Author : Lena Andersson; Håkan Westberg; Gunilla Lindström; Per Gustavsson; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Case-control study; crystalline silica; exposure assessment; iron foundry; lung cancer; morbidity; occupational hygiene; respirable quartz; Enviromental Science; Miljövetenskap;

   Abstract : The aims of the studies underlying this thesis were to assess the exposure to quartz in Swedish iron foundries and to determine the cancer morbidity for Swedish foundry workers. A cohort of 3,045 foundry workers and a final measurement database of 2,333 number of samples was established. READ MORE

5. 3. Resin acids in commercial products and the work environment of Swedish wood pellets production : Analytical methodology, occurrence and exposure

   Author : Sara Axelsson; Ulrika Nilsson; Kåre Eriksson; Håkan Westberg; Martin Harper; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rosin; resin acids; HPLC ESI-MS; air sampling; urine samples; wood pellets; wood dust; Analytical Chemistry; analytisk kemi;

   Abstract : The aims of the work this thesis is based upon were to develop convenient analytical procedures for determining resin acids in biological and environmental matrices, and apply them to enhance understanding of the occurrence, exposure to and uptake by exposed individuals of resin acids. Particular focus has been on the workplace environment of the Swedish wood pellets industry. READ MORE

6. 4. Cobalt in the hard metal production industry : exposure via inhalation and skin and the inflammatory response in human keratinocytes

   Author : Maria Klasson; Eva Särndahl; Håkan Westberg; Magnus Lindberg; Alexander Persson; Kristina Jakobsson; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cobalt; cobalt chloride; skin; HaCaT; in vitro; cell viability; pro-inflammatory cytokines; NLRP3 inflammasome;

   Abstract : Cobalt is a strong sensitizer and can cause contact allergy upon both direct contact or from airborne exposure on the skin. In the skin, keratinocytes are the first cells to come in contact with the metal and will react and respond to the danger by triggering an alarm system resulting in an inflammatory response in the skin.

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

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