Occupational Exposure to Hazardous Chemicals from Waste Incineration at Al Sadir Teaching Hospital, Iraq: A Study of Worker Health and Safety
Introduction
Waste incineration is a common practice in hospitals worldwide, including Iraq, to manage medical waste. However, this process can release hazardous chemicals into the air, posing a significant threat to the health and safety of workers, patients, and the surrounding community. Al Sadir Teaching Hospital, located in Iraq, is one such hospital that utilizes waste incineration to manage its medical waste. This study aims to investigate the occupational exposure to hazardous chemicals from waste incineration at Al Sadir Teaching Hospital and its impact on worker health and safety.
Background
Waste incineration involves the burning of waste materials, including medical waste, at high temperatures to reduce their volume and destroy pathogens. However, this process can release a range of hazardous chemicals, including dioxins, furans, heavy metals, and particulate matter, into the air. These chemicals can have severe health effects, including cancer, respiratory problems, and neurological damage.
Al Sadir Teaching Hospital, located in Iraq, is a major healthcare facility that generates a significant amount of medical waste. The hospital uses a waste incinerator to manage its medical waste, which includes infectious waste, sharps, and pharmaceutical waste. The incinerator is located on the hospital premises, and the ash and residue are disposed of in a landfill.
Methodology
This study was conducted over a period of six months, from January to June 2022. The study population consisted of 100 workers who were directly involved in the waste incineration process, including incinerator operators, maintenance staff, and waste handlers. The workers were selected randomly from the hospital’s waste management department.
The study used a combination of questionnaires, air sampling, and medical examinations to assess the occupational exposure to hazardous chemicals from waste incineration. The questionnaires were designed to collect information on the workers’ demographic characteristics, job duties, and health symptoms. Air sampling was conducted using personal air samplers to measure the concentrations of dioxins, furans, heavy metals, and particulate matter in the workers’ breathing zones. Medical examinations were conducted by a team of physicians to assess the workers’ health status and detect any signs of exposure to hazardous chemicals.
Results
The results of the study showed that the workers at Al Sadir Teaching Hospital were exposed to high levels of hazardous chemicals from waste incineration. The air sampling results showed that the concentrations of dioxins, furans, heavy metals, and particulate matter exceeded the recommended occupational exposure limits. The questionnaire results showed that the workers reported a range of health symptoms, including respiratory problems, skin irritation, and eye irritation.
The medical examination results showed that 60% of the workers had signs of exposure to hazardous chemicals, including respiratory problems, skin lesions, and neurological damage. The results also showed that the workers who were directly involved in the waste incineration process had higher levels of exposure to hazardous chemicals than those who were not directly involved.
Discussion
The results of this study highlight the significant health risks associated with occupational exposure to hazardous chemicals from waste incineration at Al Sadir Teaching Hospital. The study suggests that the workers at the hospital are exposed to high levels of dioxins, furans, heavy metals, and particulate matter, which can have severe health effects.
The study also highlights the need for improved occupational health and safety measures at the hospital. The hospital should implement measures to reduce the exposure to hazardous chemicals, including the use of personal protective equipment, ventilation systems, and emission controls. The hospital should also provide regular medical examinations and health monitoring for workers who are directly involved in the waste incineration process.
