Occupational exposures in low- and middle-income countries: A scoping review.

Exposure to high levels of harmful agents in the workplace can significantly impact workers' health, contributing to morbidity and mortality. Levels of these exposures are often measured in high-income countries in research studies and, in some places, to monitor levels in line with health and safety regulations. However, less is known about workplace exposure levels in low- and middle-income countries (LMICs). Our aim was to describe the quantitative exposure measurements of different occupational agents across industries within LMICs. We conducted a scoping review of peer-reviewed publications available on Web of Science and PubMed from inception to 1 September 2023. Our search focused on quantitative occupational exposure measurements across industries in LMICs. We identified a total of 8,676 publications. After screening, 58 studies from 25 countries were retained for final review. China, Iran, and Tanzania contributed the greatest number of studies. Manufacturing, mining, and agriculture were the most studied sectors, with factory workers and miners being the most common job titles. Exposure measurements included vapour, gases, dust, and fumes (VGDF), solvents, metals, pesticides and particulate matter. Occupational exposure levels for the same industry varied widely across geographical regions. This review provides a comprehensive overview of occupational exposures in LMICs and highlights the absence of data in certain geographical areas and industries. The study contributes valuable insights for directing future research, and the need to optimise the assessment of occupational exposures in LMICs with the aim ultimately of reducing disease.

On the Margins of the Mining Economy: Occupational Health and Safety in Artisanal Scale Gemstone Mining in the Mwatate-Voi Area, Taita Taveta County, Kenya

Artisanal gemstone mining in Kenya provides income and livelihoods to many locals in Taita Taveta County. However, little is known about the occupational safety and health issues encountered in this activity. This study investigated major occupational health and safety issues associated with artisanal gemstone mining using a variety of methods including key informant interviews, administration of questionnaires to mineworkers and direct observations at mining sites. Out of ninety-five (95) miners surveyed at ten (10) mining sites, sixty-eight (68) (71.6 %) had suffered injuries resulting in absence from work for days up to over a month. The major injury type was contusions (73.5 %). The main cause of injuries was tools/machinery handling (92.6 %). Only about twenty-seven (27) miners (28.4 %) used safety gear at work while twenty-nine (29) (30.5 %) had received any form of safety training. This study suggests that miners generally lack basic knowledge and education on the mitigation of occupational hazards associated with their work and basic tools/equipment for use in gemstone mining. Provision of education on and/or adequate enforcement of occupational health and safety regulations by relevant government agencies would improve the knowledge of miners on how to minimize occupational hazards

Quantitative Structure-Activity Relationship Models to Predict Cardiac Adverse Effects.

Drug-induced cardiotoxicity represents one of the most common causes of attrition of drug candidates in preclinical and clinical development. For this reason, the evaluation of cardiac toxicity is essential during drug development and regulatory review. In the present study, drug-induced postmarket adverse event combinations from the FDA Adverse Event Reporting System were extracted for 2002 drugs using 243 cardiac toxicity-related preferred terms (PTs). These PTs were combined into 12 groups based on their clinical relevance to serve as training sets. The optimal classification scheme was determined using a combination of data sources that included drug labeling information, published literature, clinical study data, and postmarket surveillance data. Two commercial QSAR platforms were used to construct 12 models, including general cardiac toxicity, cardiac ischemia, heart failure, cardiac valve disease, myocardial disease, pericardial disease, structural heart disease, cardiac arrhythmia, Torsades de Pointes, long QT syndrome, atrial fibrillation and ventricular arrhythmia, and cardiac arrest. The cross-validated performance for the new models reached a sensitivity of up to 80% and negative predictivity of up to 80%. These new models covering a wide range of cardiac endpoints will provide fast, reliable, and comprehensive predictions of potential cardiotoxic compounds in drug discovery and regulatory safety assessment.

Assessment of Public Transportation Safety Measures in Yaoundé, Cameroon: Case of Collective Taxis

Yaoundé, the capital of Cameroon, is one of the cities in the country most affected by road traffic crashes. Despite the measures taken by authorities, the human factor remains a major cause of these crashes. This study aimed to evaluate the measures taken to reduce the risk-taking behaviors of collective taxi drivers in Yaoundé. A survey of 144 collective taxi drivers was conducted to gather information on their driving habits, adherence to, and perceived effects of safety regulations. The study revealed the following prevalence of risky driving behaviors among collective taxi drivers: 41.33% for impaired driving; 67% for speeding, 62% for disobeying traffic lights, 68.86% for distraction; and 67% for risky maneuvering on the road. Significant associations were found between risk perceptions and involvement in risky driving behaviors. Associations were also established between the frequency of police inspections and involvement in risky behaviors, between the participation in training programs on safety issues and using poorly maintained vehicles, and between the frequency of awareness campaigns and poor maneuvering on the road. To address these issues, it is essential to strengthen preventive measures on risk factors, raise awareness on a large scale and on a regular basis, and strictly enforce the existing regulations.

The imposition of penalties within the framework of the system of employee discipline during the period of socialism in Poland

ABSTRACT The purpose of this article is to identify different forms of punishment administered on employees in Polish organisations during the socialist period. The authors discuss methods of punishment, former employees’ sentiments about their organisations’ climate and reasons for disciplinary dismissals. The material for the empirical part was collected by means of interviews. Its selection was targeted and based on snowball sampling. The majority of the interviewees claimed that the organisational climate at the time had been positive. However, acts such as favouritism of employees belonging to the ruling party, widespread shortages of tools and materials, onerous working conditions and disregard of health and safety regulations were assessed negatively. During the period under study, formal penalties were rarely applied. Managers had employment quotas to fill, and employees were not afraid of losing their jobs as they could be employed elsewhere relatively easily. Financial penalties were imposed quite often. Disciplinary dismissals were rare and occurred only when managers saw no other means of discipline left at their disposal.

Traffic Accidents: A Historical and Socio-Legal Analysis of Road Safety Challenges

Abstract This article examines the socio-legal aspects of the formation of the concept of a traffic accident, exploring its evolution from the late 19th century to the present day. The rapid growth of motor vehicles and the increasing complexity of road systems have necessitated the development of legal frameworks and safety regulations to address the risks posed by traffic accidents. The study highlights key legal milestones, such as the official introduction of the term “traffic accident” at the 1949 Geneva Conference, and analyzes the role of societal attitudes toward road safety and personal responsibility. It also delves into the cultural factors influencing traffic behavior, emphasizing the need for a comprehensive safety culture that involves drivers, pedestrians, and state regulation. By assessing the socio-legal dynamics, the article provides insights into the challenges of ensuring road safety and reducing the social and economic consequences of traffic accidents.

Agri-food fraud in Africa vis-à-vis global health

This paper reports on the extent of agri-food fraud in Africa, its occurrence across the Africa-EU trade borders, and associated implications for global health. It revealed that agri-food fraud in Africa and across Africa-EU trade borders may be a concern. Meanwhile, a few suspected cases have been reported, there may be more unchecked/unnoticed agri-food fraud practices ongoing in Africa requiring food trade border checks and rapid decisions making processes to reduce exposures. Exposure to adulterants can have significant implications for global health, as consumers unknowingly pay for, and consume, products that may be adulterated with substances which constitute a risk factor to one or more unchecked hazards against consumers' health protection. As global trade in agri-food products expands, the supply chain vulnerability to fraudulent activities becomes increasingly evident. This may be worse partly due to the inadequate food safety laws in African countries or poor enforcement. There is a need for food safety regulations in Africa that aim to ensure the safety and authenticity of food products, protect public health, and maintain consumer confidence. Finally, there is a need for rapid detection tools to make quick decisions on the field and agri-food traceability systems.

Leaky Vaccines: A Wicked Problem in Accelerated Vaccine Development

While no vaccine can provide 100 percent protection, a high standard of regulatory safety, efficacy and quality is essential for public trust and the uptake of vaccines as essential global public health tools. This article addresses a growing concern that suboptimal “leaky” vaccines threaten emergency response to pandemics as well as routine public health programs. Agile regulatory standards now advance earlier approval of vaccines and therapeutics that may have suboptimal effectiveness. The benefit-harm trade- offs that play an enormous role in regulatory assessment and all stages of vaccine development and delivery deserve better public scrutiny, transparency, and accountability. Drawing on the case of the first licensed malaria vaccine, RTS,S Mosquirix™, in light of the rapid approval of COVID-19 vaccines, we consider the socio-technical implications of leaky vaccines in global vaccine logics and suggest possibilities for building legitimacy to inform the next generation of regulatory technology policy.

Ocean wave prediction using Long Short-Term Memory (LSTM) and Extreme Gradient Boosting (XGBoost) in Tuban Regency for fisherman safety

The fishing industry has a large role in the Indonesian economy, with potential profits in 2020 of around US$ 1.338 billion. Tuban Regency is one of the regions in East Java that contributes to the fisheries sector. Fisheries relate to the work of fishermen. Accidents in shipping are still a major concern. One of the natural factors that influence shipping accidents is the height of the waves. Fisherman safety regulations have been established by the Ministry of Maritime Affairs and Fisheries and the Meteorology, Climatology and Geophysics Agency. Apart from regulations, the results of wave height predictions using the Long Short-Term Memory (LSTM) and Extreme Gradient Boosting (XGBoost) methods can help fishermen determine shipping departures, thereby reducing the risk of accidents. In this study, the Grid Search hyperparameter tuning process was used for both methods which were carried out on four location coordinates. Based on the analysis results, LSTM is superior in predicting wave height for the next 30 days because it can predict wave height at all three locations, with results at the first location (RMSE 0.045; MAE 0.029; MAPE 8.671%), second location (RMSE 0.051; MAE 0.035; MAPE 10.64%), and third location (RMSE 0.044; MAE 0.027; MAPE 7.773%), while XGBoost only has the best value at fourth location (RMSE 0.040; MAE 0.025; MAPE 7.286%).Hyperparameter tuning with gridsearch is used in LSTM and XGBoost to obtain optimal accuracyLSTM outperforms in three locations, while XGBoost outperforms in the fourth location.Advanced prediction techniques such as LSTM and XGBoost improve fishermen's safety by providing accurate wave height estimates, thereby reducing the possibility of shipping accidents.

Using benevolent leadership to improve safety behaviour in the construction industry: a moderated mediation model of safety knowledge and safety training and education

Objectives. Despite extensive regulatory reform, safety research and safety programmes over the past several decades, the construction sector remains notoriously dangerous in different regions across the world. Despite the fact that effective leadership is crucial for improving workplace safety behaviour (SB), there have been insufficient studies on how benevolent leadership (BL) affects such behaviour. Methods. Using a cross-sectional design, this research examines the influence of BL on employees’ SB. The mediating role of safety knowledge and the moderating role of safety training and education were also observed. Data obtained from 413 employees of construction firms in Turkey were used to verify the links. Results. BL has positive influences on employees’ SB and safety knowledge. Safety knowledge has a positive influence on SB and partially mediates the BL–SB link. At a low level of safety training and education, the BL–safety knowledge link is weaker for firms whose employees receive low safety training and education. At high levels of safety training and education, both the direct and indirect links between BL and SB are stronger for firms with high levels of safety training and education. Conclusion. The findings significantly extend safety literature through the lens of implicit followership theory.

Civil Law in the Context of Inheritance: Drafting a Validand Functioning Will

This study aims to analyze the legal responsibility of business owners in the case of work accidents and the implications of existing regulations on worker protection. Using a normative juridical approach, this study identifies and analyzes the legal provisions that govern the responsibilities of business owners based on applicable legislation, including the Manpower Law and related government regulations. Data was collected through literature studies that included legal literature, official documents, and analysis of court decisions relevant to work accident cases. The results of the study show that business owners have a significant responsibility in maintaining occupational safety, where a good understanding of regulations and the implementation of safety policies greatly affects the compliance of business owners. The study also identified that there are obstacles for business owners, especially small-scale ones, in meeting their legal obligations related to occupational safety. Therefore, this study recommends increased socialization regarding occupational safety regulations, as well as support for business owners to better understand and fulfill their legal obligations. It is hoped that the results of this research can contribute to the development of labor laws that are more responsive and effective in protecting workers' rights, as well as creating a safer work environment

Internet of Things Long-Range-Wide-Area-Network-Based Wireless Sensors Network for Underground Mine Monitoring: Planning an Efficient, Safe, and Sustainable Labor Environment.

Underground mines are considered one of the riskiest facilities for human activities due to numerous accidents and geotechnical failures recorded worldwide over the last century, which have resulted in unsafe labor conditions, poor health outcomes, injuries, and fatalities. One significant cause of these accidents is the inadequate or nonexistent capacity for the real-time monitoring of safety conditions in underground mines. In this context, new emerging technologies linked to the Industry 4.0 paradigm, such as sensors, the Internet of Things (IoT), and LoRaWAN (Long Range Wide Area Network) wireless connectivity, are being implemented for planning the efficient, safe, and sustainable performance of underground mine labor environments. This paper studies the implementation of an ecosystem composed of IoT sensors and LoRa wireless connectivity in a data-acquisition system, which eliminates the need for expensive cabling and manual monitoring in mining operations. Laying cables in an underground mine necessitates cable support and protection against issues, such as machinery operations, vehicle movements, mine operator activities, and groundwater intrusion. As the underground mine expands, additional sensors typically require costly cable installations unless wireless connectivity is employed. The results of this review indicate that an IoT LoRaWAN-based wireless sensor network (WSN) provides real-time data under complex conditions, effectively transmitting data through physical barriers. This network presents an attractive low-cost solution with reliable, simple, scalable, secure, and competitive characteristics compared to cable installations and manually collected readings, which are more sporadic and prone to human error. Reliable data on the behavior of the underground mine enhances productivity by improving key performance indicators (KPIs), minimizing accident risks, and promoting sustainable environmental conditions for mine operators. Finally, the adoption of IoT sensors and LoRaWAN wireless connectivity technologies provides information of the underground mine in real-time, which supports better decisions by the mining industry managers, by ensuring compliance with safety regulations, improving the productive performance, and fostering a roadmap towards more environmentally friendly labor conditions.

The characteristics, challenges, and opportunities of China’s food safety inspection supervision in the distribution sector

Concerns about public food safety are comparatively common in the Chinese food distribution industry. A dearth of expertise and scarce resources lead to frequent instances of incapacity and inadequate oversight, which negatively affect stakeholders in the circulation industry. The main challenges to food supervision are the need for more alignment between the technical specifications, comprehensiveness, and continuity of the existing food safety supervision legislation and the real circumstances facing the regulatory agencies. Despite the circulation field’s critical position in food safety regulation, its complex and variable characteristics make it challenging to implement and manage. There exist notable concerns over inadequate food safety standards and supervisory frameworks, vagueness in enforcing rules, and insufficient workforce and technical know-how in food safety supervision. The opportunities for regulating the food business with the government’s focus and attention considerably outweigh the obstacles that lie ahead. The growth of the food business needs to be viewed in the larger framework of the country’s economic development. Professional involvement and collaboration with technical departments can help regulatory bodies tackle non-compliant actions in the market circulation process in a timely way, resulting in a more evidence-based and responsive regulatory approach. Establishing a healthy equilibrium and elucidating the relationship between oversight and the food business will be crucial in the future.

The Incidence and Severity of Pediatric Injuries Sustained by Electric Bikes and Powered Scooters: The Experience of an Urban, Tertiary Pediatric Emergency Department.

This study aimed to describe the incidence and severity of electrical bicycle (E-bike)- and power scooter (P-scooter)-related injuries and their secular trends among pediatric patients presenting to a pediatric emergency department (ED). This retrospective cohort study of patients aged <18 years who sustained E-bike and P-scooter injuries was performed between 2018 and 2023. We explored trends of severe trauma cases, ED visits, hospitalizations, and surgical interventions. Severity of trauma was rated by either an injury severity score (ISS) of >15 or the patient's need for acute care as defined by intensive care unit (ICU) admission, direct disposition to the operating room, acute interventions performed in the trauma room, and in-hospital death. Of the 1466 pediatric patients who presented to our pediatric ED following P-scooter and E-bike injuries, 216 (14.7%) were hospitalized, with a median age of 14.0 years (interquartile range, 10.5-16.0 years) and male predominance (69.0%). The number of ED visits increased 3.5-fold by study closure, with a parallel increase in hospitalizations, surgical interventions, and severe trauma cases. The relative percentages of severe trauma cases were not significantly different over time. Among hospitalized patients, 3 patients (1.4%) died and 9 (4.1%) required rehabilitation care. The incidence and severity of E-bike and P-scooter injuries and fatalities continue to increase within the pediatric population. Current personal and road safety regulations are providing inadequate in preventing these injuries, highlighting an urgent need for revision and stricter enforcement.

Sub-Ppb H2S Sensing with Screen-Printed Porous ZnO/SnO2 Nanocomposite.

Hydrogen sulfide (H2S) is a highly toxic and corrosive gas commonly found in industrial emissions and natural gas processing, posing serious risks to human health and environmental safety even at low concentrations. The early detection of H2S is therefore critical for preventing accidents and ensuring compliance with safety regulations. This study presents the development of porous ZnO/SnO2-nanocomposite gas sensors tailored for the ultrasensitive detection of H2S at sub-ppb levels. Utilizing a screen-printing method, we fabricated five different sensor compositions-ranging from pure SnO2 to pure ZnO-and characterized their structural and morphological properties through X-ray diffraction (XRD) and scanning electron microscopy (SEM). Among these, the SnO2/ZnO sensor with a composition-weight ratio of 3:4 demonstrated the highest response at 325 °C, achieving a low detection limit of 0.14 ppb. The sensor was evaluated for detecting H2S concentrations ranging from 5 ppb to 500 ppb under dry, humid air and N2 conditions. The relative concentration error was carefully calculated based on analytical sensitivity, confirming the sensor's precision in measuring gas concentrations. Our findings underscore the significant advantages of mixture nanocomposites in enhancing gas sensitivity, offering promising applications in environmental monitoring and industrial safety. This research paves the way for the advancement of highly effective gas sensors capable of operating under diverse conditions with high accuracy.

Resilience Adaptation Through Risk Analysis for Wastewater Treatment Plant Operators in the Context of the European Union Resilience Directive

To combat new threats to critical infrastructure, the European Union enacted new regulations for their member states. With the directive on measures for a high common level of cybersecurity (NIS2) and the directive on critical infrastructure resilience (EU RCE), EU member states must identify critical infrastructure (CIs) and enable measures to reduce the risk of default in stress situations. The topic of resilience in urban water systems has already been of interest in previous research. However, there are still open questions. As it is a multidisciplinary term, understanding resilience and its adaptation into management systems is not an easy task for practitioners. This study will provide an overview of resilience within the framework of municipal wastewater treatment plants (WWTP) and show the current situation of existing implementation of safety and security regulations, taking Germany as an example. One of the main requirements of the EU RCE is a risk assessment (RA) for CIs. Until now, risk analysis for WWTP in research was mostly carried out for individual WWTP. By applying guidelines from the drinking water sector, this paper shows a possible methodology for a risk analysis. This paper aims to support practitioners by forming a common understanding of resilience and risk as well as providing an example for a risk analysis.

Evaluating the Human Risks of Consumption of Foods of Bovine Origin with Ivermectin Residues in Ecuador.

Ivermectin is a widely used antiparasitic in livestock, but its use can result in residues in bovine products and excretions. The objective of the present study was to determine the presence of ivermectin residues in cattle meat, liver, milk, faeces, and urine and assess consumer risk from chronic exposure through contaminated bovine products using a deterministic approach. To determine the presence of ivermectin residues, 124 samples were analysed by liquid chromatography. Residues were found in 68% of faeces samples and small percentages (3%) in liver, milk, and urine, with no residues detected in meat. The mean ivermectin residue in the liver (16.46 µg/kg) remained below the maximum residue limit (MRL); however, in milk (12.46 µg/kg), the residues exceeded the permitted MRL. The results obtained from chronic dietary exposure show that the consumption of ivermectin residues was low, and the risk was assessed as being rare to very rare. Additionally, this study reveals concerning levels of ivermectin residues in milk that may far exceed established safety limits. This situation emphasises the urgent need for stricter regulations and monitoring in milk production, particularly from small farms, to protect vulnerable populations. However, from a one health perspective, the presence of residues in faeces poses potential environmental hazards, warranting further research. Moreover, the detection of residues in milk, despite the ban on ivermectin use in dairy cattle, underscores the importance of compliance with food safety regulations and the need for continued vigilance in this area.

Assessment of knowledge, attitude and practice regarding hygiene among meat handlers in Vijayapura city, North Karnataka

Background: Food-borne diseases are a significant health concern globally, particularly in meat-related cases, due to unhygienic handling and inadequate sanitation. Challenges such as inadequate food safety regulations, weak regulatory frameworks and insufficient awareness among food handlers contribute in exacerbating the issue. The aim of this study was to evaluate knowledge, attitudes, and practices of hygiene among slaughterhouse workers in Vijayapura, north Karnataka. Objective was to evaluate the sociodemographic characteristics of meat handlers and their correlation with knowledge, attitudes, and practices related to meat hygiene in in Vijayapura, north Karnataka. Methods: This descriptive, cross-sectional study was conducted in Vijayapura city from July to September 2023, involving meat handlers from various shops. 79 participants were selected from 200 shops using a lottery method, anticipating a 71% knowledge level of meat hygiene.

Results: Among the 79 participants, 86.1% were male and 13.9% female, with 64.5% having over five years of experience. Most (96.2%) had good knowledge of meat hygiene, while 3.8% had poor knowledge. Significant associations were found between gender (p=0.00), religion (p=0.00), educational status (p=0.013), and meat hygiene practices. Conclusions: The study reveals satisfactory knowledge, attitudes, and practices regarding meat hygiene among meat handlers in Vijayapura. It is highly advisable to emphasize public health education, develop policies, and implement consistent training programs for meat handlers focused on safe meat handling practices, as well as maintaining high standards of personal and general hygiene.

Time and environmental conditions for heat stress recovery based on human physiological responses: Developing a predictive model

Breaks can protect workers exposed to high temperatures from heat stress and other health risks. However, the most suitable recovery conditions and how the body physiologically responds to them remain uncertain. The aim of this study was to provide scientific evidence of the human physiological response to step changes in environmental parameters of recovery stage through climate chamber experiments and to develop a predictive model. Volunteer subjects experienced 60 min of walking exercise in air temperatures of 32 and 36 °C, RH 60%, and an air velocity of 0.2 m/s to form two heat stress levels, and then moved into a resting space under designated environmental conditions, such as a standard effective temperature (SET) range of 15.6–26.0 °C. The results showed that the recovery time for physiological parameters decreased with decreasing SET, accompanied by a simultaneous increase in thermal discomfort rate. Correlation analysis suggested that recovery time was related to the physiological stress index at the beginning of the recovery phase (PSI0; r = 0.86) and the SET (r = 0.75) of the recovery environment. A predictive model of heat stress recovery time was developed based on PSI0 and SET, with a determination coefficient of 0.9. According to the model, a SET of 18.8–24.9 °C was suitable for people with high heat stress requiring full recovery in 15–30 min. The research findings contribute to the regulation of health and safety in high-temperature working environments and the operation of restroom environmental conditions.
