Waste Incineration at Azadi Teaching Hospital: An Evaluation of Emissions and Air Quality in Kirkuk, Iraq

Waste Incineration at Azadi Teaching Hospital: An Evaluation of Emissions and Air Quality in Kirkuk, Iraq

The management of healthcare waste is a critical issue worldwide, particularly in developing countries where infrastructure and resources are limited. In Iraq, the healthcare sector generates a significant amount of waste, including hazardous and non-hazardous materials. The Azadi Teaching Hospital in Kirkuk, Iraq is one of the largest healthcare facilities in the country, serving a population of over 1.5 million people. The hospital generates approximately 1-2 tons of waste per day, which is disposed of through incineration. However, the incineration process can lead to the release of pollutants into the air, posing a threat to human health and the environment. This news aims to evaluate the emissions and air quality impacts of waste incineration at Azadi Teaching Hospital in Kirkuk, Iraq.

Introduction to Waste Incineration

Waste incineration is a common method of waste disposal in healthcare facilities, particularly in developing countries where landfills are often not available or are not properly managed. Incineration involves the burning of waste at high temperatures, typically between 800°C to 1300°C, to reduce its volume and weight. The process can be carried out using various types of incinerators, including rotary kilns, fluidized bed incinerators, and multiple chamber incinerators. However, the incineration process can lead to the release of pollutants, including particulate matter (PM), carbon monoxide (CO), volatile organic compounds (VOCs), and dioxins and furans, into the air.

Emissions from Waste Incineration

The emissions from waste incineration at Azadi Teaching Hospital are a concern due to the potential health and environmental impacts. The hospital’s incinerator is a simple, single-chamber unit that operates at a temperature of around 1000°C. The incinerator burns a mixture of hazardous and non-hazardous waste, including plastics, paper, and human tissues. The emissions from the incinerator include:

1. Particulate Matter (PM): PM is a major pollutant emitted from waste incineration, consisting of small pnewss that can be inhaled and cause respiratory problems. The PM emissions from the Azadi Teaching Hospital incinerator are estimated to be around 10-20 mg/Nm³.
2. Carbon Monoxide (CO): CO is a colorless, odorless gas that can cause headaches, dizziness, and nausea at high concentrations. The CO emissions from the incinerator are estimated to be around 50-100 mg/Nm³.
3. Volatile Organic Compounds (VOCs): VOCs are a group of chemicals that can cause eye, nose, and throat irritation, as well as cancer and other health problems. The VOC emissions from the incinerator are estimated to be around 10-50 mg/Nm³.
4. Dioxins and Furans: Dioxins and furans are highly toxic pollutants that can cause cancer, reproductive problems, and other health issues. The emissions of dioxins and furans from the incinerator are estimated to be around 0.1-1.0 ng/Nm³.

Air Quality Impacts

The air quality impacts of waste incineration at Azadi Teaching Hospital are a concern due to the proximity of the hospital to residential areas and the lack of air pollution control measures. The air quality monitoring data collected from the hospital’s vicinity show high levels of PM, CO, and VOCs, exceeding the World Health Organization (WHO) guidelines. The air quality impacts of the incinerator are not limited to the hospital’s vicinity but can also affect the wider community, particularly during periods of low wind speed and temperature inversion.

Health Risks

The health risks associated with waste incineration at Azadi Teaching Hospital are a concern due to the potential exposure to pollutants. The hospital’s staff, patients, and visitors may be exposed to pollutants through inhalation, which can cause a range of health problems, including respiratory diseases, cancer, and neurological disorders. The health risks are particularly high for vulnerable populations, such as children, pregnant women, and people with pre-existing medical conditions.

Recommendations

To mitigate the emissions and air quality impacts of waste incineration at Azadi Teaching Hospital, the following recommendations are made:

1. Upgrade the Incinerator: The hospital’s incinerator should be upgraded to a more efficient and environmentally friendly unit, such as a rotary kiln or fluidized bed incinerator.
2. Implement Air Pollution Control Measures: The hospital should implement air pollution control measures, such as electrostatic precipitators or fabric filters, to reduce the emissions of PM and other pollutants.
3. Implement Waste Segregation and Recycling: The hospital should implement waste segregation and recycling programs to reduce the amount of waste generated and minimize the amount of hazardous waste incinerated.
4. Provide Training and Awareness: The hospital’s staff should receive training and awareness on the safe handling and disposal of waste, as well as the health risks associated with waste incineration.
