- Evaluation of occupational exposure to flour dust and additives in a milling industryPublication . Matos, Maria Luísa; Cardoso, Ricardo TeixeiraABSTRACT: This study aimed to assess an environmental risk in a workstation: the occupational exposure of workers to flour dust, and mixtures of flour dust with additives in the cereal milling industry. The purpose was to understand how exposure to flour dust, and mixtures of flour dust with additives affects the health of workers. In the facilities of the milling company where this study was carried out, there is an area where workers are particularly exposed to flour dust and mixtures of flour dust with additives involved. Therefore, one of the main objectives of this study was to evaluate if these workers were subjected to occupational health hazards during their working hours, due to the contact with suspended flour dust in their workstations, focusing special attention to this area, whenever possible. A sampling of particles suspended in the air was carried out, in order to perform a quantitative analysis. Suction pumps were used, placed on workers, who work in three different workstations, to make a quantitative comparison. An average concentration (a.c.) of 17.27 mg/m3 was obtained in the workstation of the preparation of mixtures, an a. c. of 1.35 mg/m3 and one of 2.25 mg/m3 in the bagging workstation – for plain flour and for added flour, respectively. It was found that all values obtained exceed the Exposure Limit Value proposed by the Standard NP 1796:2014, which presents a value calculated as a weighted average of 0.5 mg/m3. Mitigation with the use of personal protective equipment (PPE), FFP3 type masks, is enough to protect workers.
- Noise-Induced fatigue in maritime work environments: A cross-sectional study of occupational exposure among seafaring personnel in IndonesiaPublication . Febriyanto, Kresna; Mourão, Luis; Matos, Maria Luísa; Guedes, JoanaABSTRACT: Objective: The study aims to examine the relationship between occupational noise exposure and the levels of physical, mental, and emotional fatigue among speedboat crew members.Methods: A cross-sectional study was conducted among speedboat crew members in Tarakan, North Kalimantan, Indonesia on November 2024. This study involves two categories of ship personnel as samples, namely, crew members and captains were 87 crews were enrolled in this study. We calculated using Spearman's rho models to analysed the data.Results: The study found that occupational noise levels on speedboats ranged from 77.9 to 100.9 dB(A), with one vessel exceeding the safe exposure threshold. The level of fatigue among the respondents is mostly in the low category (69% - 74.7%). Occupational noise aboard speedboats is a significant contributor to physical (r = .715, p = .040) and mental fatigue (r = .839, p = .022).Conclusion: The results of the statistical test indicate that, besides the main research variable, other confounding variables correlate with the fatigue levels of the crew, such as age, educational background, and working period. While overall fatigue levels were low, the study highlights the need to address noise exposure and other correlated factors to safeguard seafarers well-being.
