  1. 1. Contact allergy to formaldehyde. Diagnosis and clinical relevance

    University dissertation from Occupational and Environmental Dermatology Unit

    Author : Inese Dubnika Hauksson; Lunds universitet.; Lund University.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allergic contact dermatitis; preservatives; formaldehyde; formaldehyde releasers; patch testing; repeated open application test; baseline series;

    Abstract : Preservatives are biologically active substances mainly used in water-based products to prevent the growth of microorganisms. Most people are exposed to them on a daily basis. Formaldehyde is one of the oldest and most commonly used preservatives. However, it is a well-known contact sensitiser in dermatitis patients. READ MORE

  2. 2. Optical remote sensing of industrial gas emission fluxes

    University dissertation from Occupational and Environmental Dermatology Unit

    Author : John Johansson; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical remote sensing; DOAS; gas emission; absorption spectroscopy; VOC; flux measurement; solar occultation; FTIR; formaldehyde;

    Abstract : Mobile optical remote sensing techniques offer promising possibilities to quantify and geographically attribute local industrial gaseous emissions to the atmosphere. Studies have repeatedly shown that such emissions are often poorly understood, underestimated, and thereby not properly accounted for in emission inventories and regional atmospheric chemistry models, especially for emissions of VOCs.

  3. 3. Exposure to some carcinogenic compounds in air, with special reference to wood smoke

    University dissertation from Occupational and Environmental Dermatology Unit

    Author : Pernilla Gustafson; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; formaldehyde; acetaldehyde; 1; 3-butadiene; benzene; polycyclic aromatic hydrocarbons; particulate matter; domestic wood burning; exposure assessment; personal exposure; experimental study;

    Abstract : The general population is exposed to air pollutants in both indoor and outdoor air from many different sources, including traffic, biomass burning, industries, cigarette smoking, and certain building materials. Air pollutants can cause a variety of health effects such as cancer and respiratory and cardiovascular diseases. READ MORE

  4. 4. Development and Application of Rotational Coherent Anti-Stokes Raman Spectroscopy and Laser-induced Fluorescence for Combustion Diagnostics

    University dissertation from Division of Combustion Physics, Department of Physics, Lund University

    Author : Christian Brackmann; Lunds universitet.; Lund University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser-induced Fluorescence; Formaldehyde; Biofuel; Laser technology; Laserteknik; Energy research; Energiforskning; Coherent Anti-Stokes Raman Spectroscopy; Combustion; Laser diagnostics; Fysicumarkivet A:2004:Brackmann;

    Abstract : The thesis concerns the development and application of two laser-based methods for combustion diagnostics: dual broadband rotational coherent anti-Stokes Raman spectroscopy (CARS) and laser-induced fluorescence (LIF). In efforts to increase the usefulness of the CARS technique, the applicability of a method involving a combination of the rotational CARS technique and the closely related vibrational CARS technique was investigated.

    Abstract : Popular Abstract in Swedish En spännande utmaning för forskare inom både akademin och industrin är att utveckla industriella processer som mer effektivt använder både befintliga som alternativa råvaror för produktion av viktiga kemiska intermediat. Sådana intermediat används i sin tur som råvara för att framställa funktionella och idag ovärderliga material såsom plaster, fibrer, gummin, färger, ytbehandlingsmedel m. READ MORE
