Hawler Teaching Hospital’s Waste Incinerators: A Review of Air Pollution and Health Risks in Erbil, Iraq

Introduction

Hawler Teaching Hospital, located in Erbil, Iraq, is one of the largest and most prominent healthcare facilities in the Kurdistan Region. The hospital provides essential medical services to the local population, including emergency care, surgical procedures, and ongoing treatment for various diseases. However, like many healthcare facilities worldwide, Hawler Teaching Hospital generates a significant amount of medical waste, which requires proper disposal to prevent environmental and health hazards. One of the methods used for medical waste disposal at the hospital is incineration, which involves burning waste at high temperatures to reduce its volume and sterilize it. However, incineration can also lead to air pollution and pose health risks to the surrounding community. This news reviews the air pollution and health risks associated with the waste incinerators at Hawler Teaching Hospital in Erbil, Iraq.

Background

Medical waste incineration has been a common practice in healthcare facilities for many years, as it provides a convenient and effective way to dispose of hazardous waste. However, the process of incineration releases toxic pollutants into the air, including particulate matter, carbon monoxide, volatile organic compounds, and dioxins. These pollutants can have severe health consequences, including respiratory problems, cardiovascular disease, and even cancer. In addition, the incineration process can also release heavy metals, such as lead and mercury, which can accumulate in the environment and pose long-term health risks.

Air Pollution from Hawler Teaching Hospital’s Waste Incinerators

Studies have shown that the waste incinerators at Hawler Teaching Hospital release significant amounts of air pollutants, including particulate matter, carbon monoxide, and volatile organic compounds. The hospital’s incinerators operate at temperatures ranging from 800°C to 1200°C, which is sufficient to break down organic matter but may not be enough to destroy all toxic pollutants. The incinerators are equipped with basic air pollution control devices, such as scrubbers and filters, but these may not be sufficient to remove all pollutants from the exhaust gases.

Measurements of air quality around the hospital have shown elevated levels of particulate matter, nitrogen dioxide, and sulfur dioxide, which are all associated with adverse health effects. For example, a study conducted in 2020 found that the concentration of particulate matter (PM2.5) near the hospital was significantly higher than the World Health Organization’s (WHO) guideline value of 10 μg/m³. The study also found that the levels of nitrogen dioxide and sulfur dioxide exceeded the WHO’s guideline values, indicating a potential health risk to the surrounding community.

Health Risks Associated with Air Pollution from Hawler Teaching Hospital’s Waste Incinerators

The air pollution from Hawler Teaching Hospital’s waste incinerators poses significant health risks to the surrounding community, including hospital staff, patients, and nearby residents. Exposure to particulate matter, nitrogen dioxide, and sulfur dioxide can cause respiratory problems, such as asthma and chronic obstructive pulmonary disease (COPD). Long-term exposure to these pollutants can also increase the risk of cardiovascular disease, stroke, and lung cancer.

In addition, the incineration of medical waste can release toxic pollutants, such as dioxins and heavy metals, which can accumulate in the environment and pose long-term health risks. Dioxins, for example, are known to be carcinogenic and can also cause reproductive and developmental problems. Heavy metals, such as lead and mercury, can accumulate in the body and cause neurological damage, kidney damage, and other health problems.

Mitigation Measures to Reduce Air Pollution and Health Risks

To reduce the air pollution and health risks associated with the waste incinerators at Hawler Teaching Hospital, several mitigation measures can be implemented. These include:

1. Upgrading air pollution control devices: The hospital can upgrade its air pollution control devices, such as scrubbers and filters, to more efficient models that can remove a wider range of pollutants from the exhaust gases.
2. Implementing alternative waste disposal methods: The hospital can explore alternative waste disposal methods, such as autoclaving or microwave treatment, which can reduce the amount of waste sent to incineration.
3. Improving waste segregation and management: The hospital can improve its waste segregation and management practices to reduce the amount of hazardous waste generated and ensure that only non-hazardous waste is sent to incineration.
4. Conducting regular air quality monitoring: The hospital can conduct regular air quality monitoring to track the levels of pollutants released by the incinerators and take corrective action when necessary.
5. Providing training and education: The hospital can provide training and education to its staff on the importance of proper waste disposal and the health risks associated with air pollution from incineration.
