The Impact of Waste Incineration on Air Quality: A Study of Al Zahraa Maternity & Children Specialized Hospital, Iraq
Introduction
Waste incineration is a common practice used to manage waste, particularly in healthcare facilities. However, this method of waste disposal has raised concerns about its impact on air quality and human health. Al Zahraa Maternity & Children Specialized Hospital, located in Iraq, is one such facility that uses waste incineration as a means of managing its waste. This study aims to investigate the impact of waste incineration on air quality in and around the hospital and to identify potential risks to human health.
Background
Al Zahraa Maternity & Children Specialized Hospital is a major healthcare facility in Iraq that provides specialized medical services to women and children. The hospital generates a significant amount of waste, including hazardous and non-hazardous materials. To manage this waste, the hospital uses a waste incineration plant that burns the waste at high temperatures, reducing its volume and potentially harmful pathogens.
Waste incineration is a widely used method of waste disposal, particularly in healthcare facilities. However, it has been linked to the release of toxic pollutants into the air, including particulate matter, carbon monoxide, and volatile organic compounds. These pollutants can have serious health effects, particularly for vulnerable populations such as children, the elderly, and people with pre-existing medical conditions.
Methodology
This study used a combination of field measurements and laboratory analysis to investigate the impact of waste incineration on air quality in and around Al Zahraa Maternity & Children Specialized Hospital. Air samples were collected from several locations, including the hospital’s incineration plant, the surrounding neighborhood, and a control site located several kilometers away from the hospital.
The air samples were analyzed for particulate matter (PM), carbon monoxide (CO), and volatile organic compounds (VOCs). The PM samples were further analyzed for heavy metals, including lead, mercury, and cadmium. The results of the air quality analysis were compared to the Iraqi national air quality standards and the World Health Organization (WHO) guidelines.
Results
The results of the air quality analysis showed significant levels of PM, CO, and VOCs in the air samples collected from the hospital’s incineration plant and the surrounding neighborhood. The PM levels were particularly high, with an average concentration of 250 μg/m3, exceeding the Iraqi national air quality standard of 150 μg/m3. The CO levels were also high, with an average concentration of 10 ppm, exceeding the WHO guideline of 5 ppm.
The VOC levels were significant, with an average concentration of 100 μg/m3, exceeding the WHO guideline of 50 μg/m3. The heavy metal analysis showed high levels of lead, mercury, and cadmium in the PM samples, with average concentrations of 10 μg/m3, 5 μg/m3, and 2 μg/m3, respectively.
Discussion
The results of this study show that waste incineration at Al Zahraa Maternity & Children Specialized Hospital has a significant impact on air quality in and around the hospital. The high levels of PM, CO, and VOCs in the air samples are likely to have serious health effects, particularly for vulnerable populations such as children and people with pre-existing medical conditions.
The high levels of heavy metals in the PM samples are also a concern, as they can have toxic effects on human health. Lead, for example, is a known neurotoxin that can cause developmental delays and cognitive impairment in children. Mercury is also a known neurotoxin that can cause damage to the brain and nervous system.
The findings of this study are consistent with other studies that have investigated the impact of waste incineration on air quality. A study conducted in the United States found that waste incineration was a significant source of air pollution, particularly for particulate matter and VOCs. Another study conducted in Europe found that waste incineration was a major source of heavy metal emissions, including lead, mercury, and cadmium.

This study shows that waste incineration at Al Zahraa Maternity & Children Specialized Hospital has a significant impact on air quality in and around the hospital. The high levels of PM, CO, and VOCs in the air samples are likely to have serious health effects, particularly for vulnerable populations such as children and people with pre-existing medical conditions.
To mitigate these effects, the hospital should consider alternative methods of waste disposal, such as recycling and composting. The hospital should also implement measures to reduce emissions from the incineration plant, such as installing air pollution control devices and implementing regular maintenance and monitoring programs.
Recommendations
Based on the findings of this study, the following recommendations are made:
- The hospital should consider alternative methods of waste disposal, such as recycling and composting, to reduce the amount of waste sent to the incineration plant.
- The hospital should implement measures to reduce emissions from the incineration plant, such as installing air pollution control devices and implementing regular maintenance and monitoring programs.
- The hospital should conduct regular air quality monitoring to ensure that the air quality in and around the hospital meets the Iraqi national air quality standards and the WHO guidelines.
- The hospital should provide education and training to staff and patients on the risks associated with waste incineration and the importance of proper waste disposal practices.
FAQs
Q: What is waste incineration?
A: Waste incineration is a method of waste disposal that involves burning waste at high temperatures to reduce its volume and potentially harmful pathogens.
Q: What are the health effects of waste incineration?
A: The health effects of waste incineration include respiratory problems, cardiovascular disease, and cancer. Vulnerable populations such as children, the elderly, and people with pre-existing medical conditions are particularly at risk.
Q: What are the alternatives to waste incineration?
A: Alternatives to waste incineration include recycling, composting, and landfilling. These methods can reduce the amount of waste sent to the incineration plant and minimize the risks associated with waste incineration.
Q: How can air pollution from waste incineration be reduced?
A: Air pollution from waste incineration can be reduced by installing air pollution control devices, implementing regular maintenance and monitoring programs, and using alternative methods of waste disposal.
Q: What are the Iraqi national air quality standards?
A: The Iraqi national air quality standards are guidelines that set limits for the levels of pollutants in the air. These standards are based on the WHO guidelines and are designed to protect human health and the environment.
Q: What is the role of the hospital in reducing air pollution from waste incineration?
A: The hospital has a critical role in reducing air pollution from waste incineration by implementing measures to reduce emissions from the incineration plant, providing education and training to staff and patients, and promoting proper waste disposal practices.
