With increasing concerns about the impact of outdoor air quality on public health, demand rises for cost-effective, scalable air monitoring solutions. Low-cost sensors offer promise for monitoring outdoor air quality, with potential for widespread deployment. This article presents a comprehensive evaluation methodology for these sensors, focusing on real-world outdoor performance and end-user perspectives. Relevant methodologies for evaluating wireless air monitor with low-cost sensors were sourced from databases. The study outlines rigorous field-testing methodology, addressing sensor accuracy and stability tested in diverse environmental conditions under various climatic and geographical scenarios. This study explores end-user perspectives ensuring data relevance. This research contributes to discourse on low-cost sensor use, emphasizing a comprehensive evaluation framework encompassing technical performance, usability testing, and user perspectives. Insights gained can guide reliable, user-centric air monitoring solutions, enhancing our ability to mitigate health risks from outdoor air pollution. [ABSTRACT FROM AUTHOR]

Introduction: Malaysian traffic police are always working on the public roads to alleviate traffic congestion and therefore exposed them to the polluted air every day. In particular, polluted air containing PM2.5 is dangerous to their respiratory health as they can penetrate deep into the lungs, leading to bronchitis, lung cancer and many more. Hence, this research examined the relationship of personal exposure level to PM2.5 with respiratory symptoms among traffic policemen in Kuala Lumpur and Johor Bahru. Methods: 134 participants among traffic policemen were agreed to participate in this study. They were requested to complete a questionnaire regarding the sociodemographic background and respiratory health information. The questionnaire was adopted from International Union Against Tuberculosis Lung Diseases (1986). Personal exposure level of PM2.5 was measured using an air pump with 5.0µm pore size PVC filter. Results: The mean exposure level of PM2.5 among traffic policemen was 28.69 µg/m3. It was found that some of them possess respiratory symptoms (Coughing 33.6%, Phlegm 25.4%, Wheezing 14.9% and Shortness of breath 32.1%). There was significant association detected at p-value < 0.05 in coughing. Despite, there was no significant association in other symptoms such as phlegm, wheezing and shortness of breath. Conclusions: Traffic police were exposed to a relatively high level of PM2.5 (12.4 µg/m3 to 55.3 µg/m3) and showed symptoms of respiratory effects. Therefore, recognition of the risks connected with occupational lung disease and exposure monitoring must be a high priority. This baseline data can serve as a reference to the top management of traffic police officers in order to develop an occupational safety and health guideline for police officers as required by Occupational Safety and Health Act (OSHA, Act 514 1994).

Introduction: Musculoskeletal Disorders (MSDs) are a common occupational health problem among police officers. This systematic review aimed to estimate the association between psychosocial factors and MSDs in this population. Design: A systematic search was conducted using the Scopus database to identify studies that assessed the psychosocial risk factors for MSDs in police officers. Results: Fourteen studies were included in the review. The findings suggest that exposure to job satisfaction, working type, job demands, shift work, working hours, job control, equipment, organisational structure, job support, work cooperation, workplace inequalities, parenthood, social support, and psychological factors were linked to the presence of pain in the back, neck, shoulder, arm, and legs among police officers. Conclusions: This review highlights the importance of addressing psychosocial risk factors to improve the quality of life of police officers. Specific interventions to reduce these risk factors might include changes in organizational structure, job design, and work schedules, as well as targeted programs to promote stress management, coping skills, and work-life balance. Addressing these factors can help to prevent or reduce the presence of MSDs in this population, promoting healthier and more productive workplaces. Future studies are recommended to investigate this association further by considering the utilization of longitudinal study designs. [ABSTRACT FROM AUTHOR]

Introduction: Traffic policemen are exposed to polluted air for a long time in high concentrations since they are working outside for most of the time which is bad for their health. Hence, this study was to determine the prevalence of respiratory symptoms and pulmonary function among traffic police in Kuala Lumpur and Johor Bahru. Methods: A pulmonary function test using spirometer was used to measure the pulmonary function of subjects. A questionnaire on respiratory symptoms translated version from IUALTD was used. The questionnaire includes background data, occupational and health history. Results: The traffic policemen were determined as having lower lung function parameters; low FVC% predicted (89.6%) and low FEV1% predicted (94%) due to their nature of work and the environment. Coughing was present at the highest (33.6%) among them, whereas wheezing was found the least (15.7%) of the workers. Conclusions: Findings from this study, indicated that there is a development of respiratory diseases and deterioration of lung function among traffic policemen. These baseline data can serve as a reference to the top management of traffic police officers in order to develop an occupational safety and health guideline for police officers as they are not covered by Occupational Safety and Health Act (OSHA, Act 514 1994).
