Evaluation of Air Pollution Emissions from Medical Waste Incinerators at Baladrus General Hospital, Iraq
Introduction
Medical waste incineration is a common practice in hospitals for the disposal of hazardous waste, including infectious and non-infectious waste. However, this process can lead to the release of toxic pollutants into the atmosphere, posing significant environmental and health risks. In Iraq, the lack of effective waste management systems and inadequate regulations has led to uncontrolled emissions from medical waste incinerators, compromising air quality and human health. This news evaluates the air pollution emissions from medical waste incinerators at Baladrus General Hospital in Iraq, highlighting the need for improved waste management practices and regulatory frameworks.
Background
Medical waste incineration is a widely used method for disposing of hazardous waste in healthcare facilities. Incineration involves the combustion of waste at high temperatures, reducing the volume of waste and killing pathogens. However, this process can lead to the formation of pollutants, including particulate matter (PM), carbon monoxide (CO), volatile organic compounds (VOCs), dioxins, and furans. These pollutants can cause respiratory problems, cancer, and other health issues, and can also contribute to climate change.
In Iraq, the healthcare sector generates a significant amount of medical waste, estimated to be around 150-200 kg per day per hospital. The lack of effective waste management systems and inadequate regulations has led to uncontrolled emissions from medical waste incinerators, compromising air quality and human health. The Baladrus General Hospital, located! in Baghdad, is one of the largest hospitals in Iraq, generating a significant amount of medical waste.
Methodology
This study aimed to evaluate the air pollution emissions from medical waste incinerators at Baladrus General Hospital in Iraq. The study involved a combination of field measurements and laboratory analysis. Field measurements were conducted using a portable air quality monitoring system to measure PM, CO, VOCs, and other pollutants. The monitoring system was placed near the incinerator stack to measure the emissions directly.
Laboratory analysis involved collecting and analyzing ash and particulate matter samples from the incinerator. The ash samples were analyzed for heavy metals, including lead, mercury, and cadmium, using atomic absorption spectroscopy. Particulate matter samples were analyzed for VOCs and other organic compounds using gas chromatography-mass spectrometry.
Results
The results of the study showed that the medical waste incinerator at Baladrus General Hospital emitted significant amounts of pollutants, including PM, CO, VOCs, and heavy metals. The concentrations of these pollutants exceeded the World Health Organization (WHO) guidelines for air quality, posing significant health risks to patients, staff, and surrounding communities.
The PM concentrations measured near the incinerator stack were as high as 500 μg/m3, exceeding the WHO guideline of 20 μg/m3. The CO concentrations were also high, ranging from 10-50 ppm, exceeding the WHO guideline of 0-10 ppm. VOCs, including benzene, toluene, and xylene, were detected in the air samples, with concentrations ranging from 1-5 μg/m3.
The ash samples analyzed for heavy metals showed high concentrations of lead, mercury, and cadmium, exceeding the WHO guidelines. The particulate matter samples analyzed for VOCs and other organic compounds showed the presence of dioxins and furans, known carcinogens.
Discussion
The results of this study highlight the need for improved waste management practices and regulatory frameworks in Iraq. The emissions from medical waste incinerators at Baladrus General Hospital pose significant environmental and health risks, compromising air quality and human health. The lack of effective regulations and enforcement has led to uncontrolled emissions, and it is essential to establish and implement strict guidelines for medical waste management.
The use of alternative waste management technologies, such as autoclaving and microwave treatment, should be considered to reduce the reliance on incineration. These technologies can significantly reduce the volume of waste and minimize the formation of pollutants.
