Can selection explain the protective effects of farming on asthma?
Wijnand, Eduard; Schlunssen, Vivi; Sigsgaard, Torben; Omland, Øyvind; Pearce, Neil; Douwes, Jeroen (Peer reviewed; Journal article, 2015)Introduction and objective: Reduced asthma and allergy risks in farmers have been ascribed to microbial exposures. However, selection may also play a role and this was assessed in two Scandinavian farming populations. ... -
Characterization and pro‐inflammatory potential of indoor mold particles
Holme, Jørn Andreas; Øya, Elisabeth Tveiten; Afanou, Komlavi Anani; Øvrevik, Johan; Wijnand, Eduard (Peer reviewed; Journal article, 2020)A number of epidemiological studies find an association between indoor air dampness and respiratory health effects. This is often suggested to be linked to enhanced mold growth. However, the role of mold are obviously ... -
Chemical Composition of Thoracic Dust at Workplaces During Cement Production
Weinbruch, Stephan; Scerri, Mark; Wijnand, Eduard; Thomassen, Yngvar; Nordby, Karl-Christian; Berlinger, Balazs; Dahl, Kari; Friisk, Grete; Romanova, Natalya; Notø, Hilde Pettersen (Peer reviewed; Journal article, 2023)Objectives Cement belongs to the most used building materials. Clinker is the major constituent of cement, and it is believed that the strong increase of pH after hydration of clinker minerals is responsible for the observed ... -
Cross-shift study of exposure–response relationships between bioaerosol exposure and respiratory effects in the Norwegian grain and animal feed production industry
Straumfors, Anne; Heldal, Kari Emilie; Wijnand, Eduard; Wouters, Inge M.; Ellingsen, Dag; Skogstad, Marit (Peer reviewed; Journal article, 2016)Objective: We have studied cross-shift respiratory responses of several individual bioaerosol components of the dust in the grain and feed industry in Norway. Methods: Cross-shift changes in lung function and nasal congestion, ... -
Exposure to wood dust, microbial components, and terpenes in the Norwegian sawmill industry
Straumfors, Anne; Olsen, Raymond; Daae, Hanne Line; Afanou, Komlavi Anani; McLean, D.; Corbin, M.; Mannetje, A.; Ulvestad, Bente; Bakke, Berit; Johnsen, Helle Laier; Douwes, J.; Wijnand, Eduard (Peer reviewed; Journal article, 2018)Sawmill workers are exposed to wood dust (a well-known carcinogen), microorganisms, endotoxins, resin acids (diterpenes), and vapours containing terpenes, which may cause skin irritation, allergy, and respiratory symptoms ... -
Fungal fragments and fungal aerosol composition in sawmills
Afanou, Komlavi Anani; Wijnand, Eduard; Johnsen, Helle Laier; Straumfors, Anne (Peer reviewed; Journal article, 2018)Assessment of exposure to fungi has commonly been limited to fungal spore measurements that have shown associations between fungi and development or exacerbation of different airway diseases. Because large numbers of ... -
Indirect immunodetection of fungal fragments by field emission scanning electron microscopy
Afanou, Komlavi Anani; Straumfors, Anne; Skogstad, Asbjørn; Nayak, Ajay P.; Skaar, Ida; Hjeljord, Linda; Tronsmo, Arne; Wijnand, Eduard; Green, Brett James (Peer reviewed; Journal article, 2015)Submicronic fungal fragments have been observed in in vitro aerosolization experiments. The occurrence of these particles has therefore been suggested to contribute to respiratory health problems observed in mold-contaminated ... -
Job tasks as determinants of thoracic aerosol exposure in the cement production industry
Notø, Hilde Pettersen; Nordby, Karl-Christian; Skare, Øivind; Wijnand, Eduard (Peer reviewed; Journal article, 2018)Background: The aims of this study were to identify important determinants and investigate the variance components of thoracic aerosol exposure for the workers in the production departments of European cement plants. ... -
Predictors for increased and reduced rat and mouse allergen exposure in laboratory animal facilities
Straumfors, Anne; Wijnand, Eduard; Andresen, Knut; Sjaastad, Ann Kristin (Peer reviewed; Journal article, 2018)Introduction: Exposure to rat and mouse allergens during work in laboratory animal facilities represents a risk for being sensitized and developing allergic diseases, and it is important to keep the exposure level as low ... -
Profile and morphology of fungal aerosols characterized by field emission scanning electron microscopy (FESEM)
Afanou, Komlavi Anani; Straumfors, Anne; Skogstad, Asbjørn; Skaar, Ida; Hjeljord, Linda; Skare, Øivind; Green, Brett James; Tronsmo, Arne; Wijnand, Eduard (Peer reviewed; Journal article, 2015)Fungal aerosols consist of spores and fragments with diverse array of morphologies; however, the size, shape, and origin of the constituents require further characterization. In this study, we characterize the profile of ... -
Profiling of 3-hydroxy fatty acids as environmental markers of endotoxin using liquid chromatography coupled to tandem mass spectrometry
Uhlig, Silvio; Negård, Mariell; Heldal, Kari Emilie; Straumfors, Anne; Madsø, Lene; Bakke, Berit; Wijnand, Eduard (Peer reviewed; Journal article, 2016)3-Hydroxy acids are constituents of the lipid A part of lipopolysaccharides and may potentially be used as chemical markers of endotoxin. While commercial enzymatic assays, such as the widely used Limulus amebocyte lysate ... -
