Physiochemical Analysis of Municipal Solid Waste Leachate from Open Dumpsites in Benin City Metropolis

Physiochemical assessment of leachate in three open dumpsites in Oluku, Uselu and New Benin in Benin City was carried out in this study using  standard methods. The pH of leachate sample from Oluku dumpsite was ultra-acidic (3.4) with electrical conductivity of 1650 μS/cm. However pH of leachate samples (7.4 and 8.6) collected from Uselu Market dumpsite and New Benin dumpsite were in the alkaline range with electrical conductivity of 8600 and 9800 μS/cm. The aforementioned approach was employed at distances of 2m and 5m from the mid-sections of these dumpsites and pH of leachate at a distance of 5m from the three were observed to be in the neutral range. The physiochemical analysis indicated the hazards of open waste dumping, as  leachate in these dumping sites contains ammonia, calcium carbonate, nitrate, sulphate and other heavy metals which can percolate and contaminate surface water and ground water thereby, causing negative effects on public health safety and the environment.Keywords: Leachate, Open dumpsites, Organic wastes, Contaminants

Physical survey on the health hazards of welding activities on welding operators in Uyo, Nigeria

Background: Welding operators are subjected to several forms of hazards during welding activities. Aim: The study aimed to identify the common practices in welding operations, assess the potential health hazards associated with these practices, and propose recommendations for improving the well-being of welding operators. Methodology: The survey was conducted at different welding workshops in Uyo, Akwa Ibom State, Nigeria. A total of 100 welding operators were observed and interviewed to gather data on their working practices and the health effects they experienced. Results: The findings revealed that the most common welding practices included manual metal arc welding, gas metal arc welding, and gas tungsten arc welding. These practices involved exposure to various hazards such as fumes, gases, noise, and ultraviolet radiation. The survey also found that a significant number of welding operators reported experiencing health issues such as respiratory problems, skin irritation, eye injuries, and hearing loss. These health effects were attributed to the lack of proper ventilation, inadequate personal protective equipment, and poor ergonomic practices in the welding workshops. Conclusion: The findings of this study highlights the importance of addressing the health hazards associated with welding operations to ensure a safer and healthier work environment for improved work conditions and well-being of welding operators. In light of the findings, several recommendations including the implementation of proper ventilation systems, provision of adequate personal protective equipment, regular health screening for welding operators, and training programs on safe welding practices is proposed in order to improve the well-being of welding operator

Overview of the role of medical robotics in day-to-day healthcare services: A paradigm shift in clinical operations

Background: Medical robotics has become an integral part of day-to-day healthcare services, revolutionizing the way medical procedures are performed and improving patient outcome. Aim: This study explored the role of medical robotics in healthcare, focusing on its impact on various aspects of patient care. Methodology: The methodology used in this study involved a comprehensive review of existing literature on medical robotics and its applications in healthcare settings. Results: The findings reveals that medical robotics has significantly enhanced the precision, efficiency, and safety of medical procedures, leading to reduced invasiveness, and faster recovery times for patients. Additionally, medical robotics has enabled healthcare providers to perform complex surgeries with greater accuracy and minimal invasiveness, ultimately improving the quality of care for patients. The findings obtained from this study also showed that robotic surgery results in fewer complications and shorter hospital stays compared to traditional surgical methods. This results in a growing adoption of robotic-assisted surgery in various medical specialties, such as urology, gynaecology, and orthopaedics. In addition to surgical procedures, medical robotics is also being used in diagnostic and therapeutic applications. For example, robotic systems are being developed for minimally invasive procedures, such as biopsies and drug delivery. Furthermore, robotic devices are being used in rehabilitation and physical therapy to assist patients in regaining mobility and function. Conclusion: One of the main concerns is the cost of implementing and maintaining robotic systems, which can be prohibitive for some healthcare facilities. Also, there are concerns about the potential for errors and malfunctions in robotic systems, which could compromise patient safety. Overall, the integration of medical robotics in day-to-day healthcare services has proven to be a game-changer, offering new possibilities for the future of healthcare delivery
