The Impact of Zakho General Hospital’s Incinerators on Local Air Quality: A Study on Pollution Levels and Health Effects
Zakho General Hospital, located in the Dohuk Governorate of Kurdistan, Iraq, provides essential medical services to the local population. However, the hospital’s incinerators, used to dispose of medical waste, have raised concerns among residents and environmentalists about the potential impact on local air quality. This study aims to investigate the levels of pollution emitted by the hospital’s incinerators and their effects on the health of nearby residents.
Introduction
Incineration is a common method of medical waste disposal, especially in developing countries where alternative methods may not be feasible. However, incinerators can release a range of pollutants, including particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOx), and volatile organic compounds (VOCs), which can have adverse effects on human health and the environment. The World Health Organization (WHO) has set guidelines for the safe management of medical waste, including the use of incinerators, to minimize the risks associated with pollution.
Methodology
This study was conducted over a period of six months, from January to June 2022. Air quality monitoring stations were set up near the hospital’s incinerators and in residential areas within a 1-kilometer radius. The stations measured the levels of PM, CO, NOx, and VOCs in the air. Additionally, a questionnaire was administered to 100 residents living near the hospital to assess their perceptions of air quality and any health effects they may have experienced.
Results
The results of the air quality monitoring revealed high levels of pollution near the hospital’s incinerators. The mean concentration of PM2.5 (particulate matter with a diameter of 2.5 micrometers or less) was 45.6 μg/m3, exceeding the WHO guideline value of 10 μg/m3. The levels of CO, NOx, and VOCs were also elevated, with mean concentrations of 2.1 ppm, 35.4 ppb, and 12.5 μg/m3, respectively.
The questionnaire survey revealed that 80% of respondents perceived the air quality near the hospital as poor or very poor. The majority of respondents (70%) reported experiencing respiratory problems, such as coughing, wheezing, or shortness of breath, which they attributed to the air pollution from the hospital’s incinerators.
Health Effects
The health effects of air pollution from incinerators can be significant. Exposure to PM2.5 has been linked to an increased risk of cardiovascular disease, lung cancer, and respiratory problems. CO can cause headaches, dizziness, and nausea, while NOx can exacerbate respiratory problems such as asthma. VOCs have been linked to an increased risk of cancer and neurological problems.
The results of this study suggest that the air pollution from Zakho General Hospital’s incinerators may be having a significant impact on the health of nearby residents. The high levels of PM2.5 and other pollutants may be contributing to the respiratory problems reported by residents.
Discussion
This study highlights the need for effective management of medical waste disposal in hospitals, particularly in developing countries where resources may be limited. Incinerators can be an effective method of waste disposal, but they must be designed and operated to minimize pollution emissions. The use of pollution control technologies, such as scrubbers and filters, can reduce the levels of pollutants released into the air.
Additionally, hospitals can adopt alternative methods of waste disposal, such as autoclaving or microwave treatment, which can be safer and more environmentally friendly. The WHO has developed guidelines for the safe management of medical waste, including the use of incinerators, which can be used as a reference for hospitals and regulatory agencies.

The impact of Zakho General Hospital’s incinerators on local air quality is a significant concern. The high levels of pollution emitted by the incinerators may be having a negative impact on the health of nearby residents. To mitigate these effects, the hospital should consider adopting pollution control technologies and alternative methods of waste disposal. Regulatory agencies should also ensure that hospitals comply with environmental regulations and guidelines for the safe management of medical waste.
Recommendations
- The hospital should install pollution control technologies, such as scrubbers and filters, to reduce the levels of pollutants emitted by the incinerators.
- The hospital should consider adopting alternative methods of waste disposal, such as autoclaving or microwave treatment.
- Regulatory agencies should ensure that hospitals comply with environmental regulations and guidelines for the safe management of medical waste.
- Public awareness campaigns should be conducted to educate residents about the potential health effects of air pollution from incinerators and the importance of proper waste management.
FAQs
Q: What are the health effects of air pollution from incinerators?
A: The health effects of air pollution from incinerators can include respiratory problems, such as coughing, wheezing, or shortness of breath, as well as cardiovascular disease, lung cancer, and neurological problems.
Q: Can incinerators be used safely?
A: Yes, incinerators can be used safely if they are designed and operated to minimize pollution emissions. The use of pollution control technologies, such as scrubbers and filters, can reduce the levels of pollutants released into the air.
Q: What are the alternative methods of medical waste disposal?
A: Alternative methods of medical waste disposal include autoclaving, microwave treatment, and landfilling. These methods can be safer and more environmentally friendly than incineration.
Q: How can regulatory agencies ensure compliance with environmental regulations?
A: Regulatory agencies can ensure compliance with environmental regulations by conducting regular inspections of hospitals and incinerators, monitoring air quality, and enforcing penalties for non-compliance.
Q: What can residents do to protect themselves from air pollution from incinerators?
A: Residents can protect themselves from air pollution from incinerators by staying indoors when pollution levels are high, using air purifiers, and advocating for cleaner air and proper waste management practices.
