Cellular responses induced by environmental stress factors in Arctic Seabird chicks : Responses of the antioxidant defense system and autophagic lysosomal processes related to contaminant exposure and food restriction
Hegseth, Marit Nøst (Doctoral thesis; Doktorgradsavhandling, 2011-11-29)This PhD study has investigated how two commonly occurring environmental stress factors in the Arctic (periods with little food and exposure to halogenated organic contaminants) have had an impact on two important cellular defense mechanisms in Arctic seabirds. The antioxidant defense system and autophagic lysosomal responses in liver cells of Arctic seabird chicks have been studied. Samples ... -
Do Various Respirator Models Fit the Workers in the Norwegian Smelting Industry?
Føreland, Solveig; Robertsen, Øystein; Hegseth, Marit Nøst (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-19)<p><i>Background - </i>Respirator fit testing is a method to assess if the respirator provides an adequate face seal for the worker. <p><i>Methods - </i>Workers from four Norwegian smelters were invited to participate in the study, and 701 respirator fit tests were performed on 127 workers. Fourteen respirator models were included: one FFABE1P3 and 11 FFP3 respirator models produced in one size and ... -
The effect of a knowledge-based intervention on the use of respirators in the Norwegian smelter industry
Robertsen, Øystein; Hegseth, Marit Nøst; Føreland, Solveig; Siebler, Frank; Eisemann, Martin; Vangberg, Hans Christian Bones (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-20)<i>Introduction</i>: The present study investigated the effect of interventions aiming to improve attitudes toward the use of respiratory protective equipment (RPE), knowledge of RPE and the use of RPE in the Norwegian smelter industry.<p><p> <i>Method</i>: The surveys received 567 respondents to baseline and 240 respondents 2 weeks after the intervention. Participants were invited to either a ... -
Predictors of respiratory protective equipment use in the Norwegian smelter industry: The role of the Theory of Planned Behavior, safety climate and work experience in understanding protective behavior
Robertsen, Øystein; Siebler, Frank; Eisemann, Martin; Hegseth, Marit Nøst; Føreland, Solveig; Vangberg, Hans Christian Bones (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-08)Previous research has revealed a higher prevalence of respiratory symptoms in Norwegian smelter workers compared to average population controls. Nevertheless, respiratory protective equipment (RPE) is not always used, even in situations with high exposure risk. A questionnaire was distributed to workers in the Norwegian smelting industry to investigate the relationship between psychological ... -
Self-reported traffic-related air pollution and respiratory symptoms among adults in an area with modest levels of traffic
Hegseth, Marit Nøst; Oftedal, Bente Margaret; Höper, Anje Christina; Aminoff, Anna Louise; Thomassen, Marte Renate; Svendsen, Martin Veel; Fell, Anne Kristin Møller (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-12)Health effects of traffic-related air pollution (TRAP) concentrations in densely populated areas are previously described. However, there is still a lack of knowledge of the health effects of moderate TRAP levels. The aim of the current study, a population-based survey including 16 099 adults (response rate 33%), was to assess the relationship between TRAP estimates and respiratory symptoms in an ...
