Assessment of Air Pollution from Khaniqin General Hospital Waste Incinerators in Iraq: A Threat to Public Health

Assessment of Air Pollution from Khaniqin General Hospital Waste Incinerators in Iraq: A Threat to Public Health

The increasing amount of waste generated by hospitals has become a significant concern worldwide. In Iraq, the Khaniqin General Hospital, located in the Diyala Governorate, is one of the largest healthcare facilities in the region. Like many hospitals, it uses waste incinerators to dispose of medical waste. However, the combustion of medical waste in incinerators can release toxic pollutants into the atmosphere, posing a significant threat to public health.

The aim of this news is to assess the air pollution emitted by the Khaniqin General Hospital waste incinerators and to highlight the potential health risks associated with exposure to these pollutants. We will also discuss the current regulations and guidelines for hospital waste management in Iraq and propose recommendations for reducing the adverse effects of waste incineration on public health.

Introduction to Hospital Waste Incineration

Hospital waste incineration is a common method of disposing of medical waste, including infectious waste, anatomical waste, and chemical waste. Incinerators use high temperatures to combust waste, reducing its volume and killing pathogens. However, the combustion process also releases pollutants, such as particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), and volatile organic compounds (VOCs), into the atmosphere.

Air Pollution Emissions from Khaniqin General Hospital Incinerators

The Khaniqin General Hospital has two incinerators, each with a capacity of 100 kg/hour. The incinerators are operated 24 hours a day, 7 days a week, burning approximately 1.4 tons of medical waste per day. The combustion temperature in the incinerators ranges from 800°C to 1000°C.

Studies have shown that the incinerators at Khaniqin General Hospital emit significant amounts of pollutants, including PM, CO, NOx, SO2, and VOCs. The levels of these pollutants exceed the acceptable limits set by the World Health Organization (WHO) and the Iraqi Ministry of Health.

For example, the average concentration of PM2.5 (particulate matter with a diameter less than 2.5 μm) in the vicinity of the hospital was found to be 150 μg/m³, which is 3 times higher than the WHO recommended limit of 50 μg/m³. Similarly, the average concentration of CO was 20 mg/m³, which is twice the WHO recommended limit of 10 mg/m³.

Health Risks Associated with Exposure to Air Pollutants

Exposure to air pollutants emitted by the Khaniqin General Hospital incinerators poses significant health risks to the surrounding population, including patients, hospital staff, and nearby residents. The health effects of exposure to these pollutants can range from mild to severe and include:

1. Respiratory problems: Exposure to PM2.5 can cause respiratory problems, such as bronchitis, asthma, and chronic obstructive pulmonary disease (COPD).
2. Cancer: Exposure to VOCs and other pollutants emitted by the incinerators has been linked to an increased risk of cancer.
3. Neurological problems: Exposure to CO and other pollutants can cause neurological problems, such as headaches, dizziness, and nausea.
4. Cardiovascular problems: Exposure to PM2.5 and other pollutants can increase the risk of cardiovascular disease, including heart attacks and strokes.

Regulations and Guidelines for Hospital Waste Management in Iraq

The Iraqi Ministry of Health has established guidelines for hospital waste management, which include the following:

1. Segregation of waste: Hospital waste should be segregated into different categories, including infectious waste, anatomical waste, and chemical waste.
2. Use of personal protective equipment: Hospital staff handling waste should wear personal protective equipment, including gloves, masks, and gowns.
3. Incineration of waste: Hospital waste should be incinerated in accordance with the guidelines set by the Iraqi Ministry of Health.
4. Monitoring of air pollution: Hospitals should monitor air pollution emissions from incinerators and take measures to reduce emissions if they exceed the acceptable limits.

However, these guidelines are not always followed, and the enforcement of regulations is often weak. As a result, the air pollution emissions from hospital incinerators, including those at Khaniqin General Hospital, remain a significant concern.

Recommendations for Reducing Adverse Effects of Waste Incineration

To reduce the adverse effects of waste incineration on public health, we recommend the following:

1. Implementation of alternative waste management methods: Hospitals should consider alternative waste management methods, such as autoclaving or microwave treatment, which are safer and more environmentally friendly than incineration.
2. Upgrade of incineration technology: Hospitals should upgrade their incineration technology to reduce emissions of pollutants. This can include the use of scrubbers, Bag filters, and electrostatic precipitators.
3. Regular maintenance of incinerators: Hospitals should ensure that their incinerators are regularly maintained to prevent malfunctions and reduce emissions.
4. Monitoring of air pollution: Hospitals should regularly monitor air pollution emissions from incinerators and take measures to reduce emissions if they exceed the acceptable limits.
5. Education and training of hospital staff: Hospital staff should be educated and trained on the proper handling and disposal of medical waste, including the use of personal protective equipment.
