Aspects of control measures in occupational hygiene

    Research output: Thesisinternal PhD, WU


    <br/>This thesis focuses on two aspects which are of major importance in the broad field of control measures in occupational hygiene: the selection of control measures in a structured way and the impact of factors modifying the effectiveness of these control measures.<p>The main objectives of the thesis are to determine the feasibility of a model approach in the selection of control measures and to assess the impact of work practices on the exposure to and uptake of chemical agents.<p>Two models, i.e. the "dynamic model of exposure, susceptibility and effect" and the "multiple source model" describe the impact of control measures on workers' exposure. The feasibility of these models and the impact of the factors modifying the effectiveness of control measures was studied in the occupational hygiene practice by performing field studies at different types of workplaces: chromium plateries, lead smelter, battery factory and at construction sites.<p>In the lead and chromium industries environmental and biological monitoring was carried out together with observations and questionnaires to assess hygienic behaviour. In the construction industry quartz exposure was characterized by personal air sampling and workplace observations.<p>From the results of these studies it can be concluded that the application of the two models proved to be an important aid in the determination of sources of exposure. Consequently the selection of control measures in different branches of industry was facilitated.<p>The differences in individual hygienic behaviour and working methods proved to be an important modifier of the relation between external and internal exposure. These results indicate that work practices need to be considered in the implementation of control measures.
