  • Impact of Oporto Metropolitan Area carbon dioxide emissions over the adjacent coastal zone
    Publication . Carvalho, Rogério; Barros, Nelson; Duarte, Pedro
    Concerns about global warming over the last years have stimulated a large number of studies regarding atmospheric and oceanic carbon dioxide (CO2) concentration and its consequences. In spite of the available data on global atmospheric CO2, there is only limited knowledge on CO2 variability at regional scales. Moreover, there is an important gap in our understanding of the contribution of high CO2 emission regions, such as metropolitan areas, to CO2 concentrations over nearby coastal areas–considered by several authors as an important CO2 sink. A possible working hypothesis is that, large littoral metropolitan areas may have a significant influence on CO2 atmospheric concentrations over those areas and exert an important influence on sea-air CO2 exchanges. Therefore, the main objective of this study is to estimate CO2 concentration at a regional scale, under the influence of Oporto Metropolitan Area (OMA) emissions as a first test of this hypothesis. To fulfil this objective, an emission database was built and used to force, together with meteorological synoptic data, a mesoscale atmospheric dispersion model. The model was used to simulate several weather scenarios and estimate CO2 concentrations along a ca. 90 km stretch of the Portuguese northern shore. The results obtained suggest that emissions from OMA have an important influence on CO2 atmospheric concentrations up to 6–12 km offshore, particularly in autumn and winter. However, this CO2 increase does not seem to have the potential to significantly affect sea-air CO2 exchanges, although this is just a preliminary conclusion that has to be tested by field work.
  • Self-reported work-related musculoskeletal disorders among health professionals at a hospital in Portugal
    Publication . Fernandes, Carla Sílvia Neves da Nova; Couto, Germano; Carvalho, Rogério; Ferreira, Patricia; Fernandes, Daniela
    Background: Work-related musculoskeletal disorders (WMSDs) are responsible for morbidity among many health professionals. Objective: To establish the prevalence of self-reported WMSDs among health professionals. Methods: Descriptive and exploratory study with health professionals at a hospital in northern Portugal. Data were collected in December 2017 by means of an electronic questionnaire applied to the total target population (n=435). We applied instruments for sociodemographic characterization, perception of knowledge on ergonomics and manual mobilization of loads, the Patient Handling Burden Scale (PHBS) and the Nordic Musculoskeletal Questionnaire (NMQ) for self-reporting musculoskeletal symptoms. Results: The sample comprised 105 professionals, mainly nurses and nursing assistants, who exhibited high frequency of symptoms in several body areas, mainly the spine. Conclusions: WMSDs involving health professionals should be considered a problem for health institutions which do not implement interventions beyond traditional training programs, especially multifactorial programs of systemic nature.
