Waste Incineration and Health Risks: A Study of Occupational Exposure to Pollutants at Al Fayhaa General Teaching Hospital, Iraq

Waste incineration is a common practice used to manage medical waste, particularly in healthcare facilities. However, the process of burning waste releases toxic pollutants into the air, posing significant health risks to individuals living and working nearby. This news examines the occupational exposure to pollutants among healthcare workers at Al Fayhaa General Teaching Hospital in Iraq, highlighting the potential health risks associated with waste incineration.

Introduction

The management of medical waste is a critical issue in healthcare facilities worldwide. Waste incineration is a widely used method for disposing of medical waste, particularly in developing countries where waste management infrastructure is limited. However, the incineration process releases a range of toxic pollutants, including particulate matter (PM), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and heavy metals, into the air. These pollutants can have adverse effects on human health, particularly among individuals who are occupationally exposed to them.

Background

Al Fayhaa General Teaching Hospital is a major healthcare facility located in Basra, Iraq. The hospital generates a significant amount of medical waste, including infectious and non-infectious waste, which is incinerated on-site. The incineration process is carried out in a brick-lined furnace, with minimal emission control measures in place. Healthcare workers at the hospital, including doctors, nurses, and maintenance staff, are potentially exposed to pollutants emitted during the incineration process.

Methodology

A cross-sectional study was conducted to assess the occupational exposure to pollutants among healthcare workers at Al Fayhaa General Teaching Hospital. The study included 100 healthcare workers who were divided into two groups: those who worked in areas where waste incineration took place (exposed group) and those who worked in areas where waste incineration did not take place (non-exposed group). Air samples were collected from both groups using personal air samplers, and analyzed for PM, VOCs, PAHs, and heavy metals. Questionnaires were also administered to collect information on demographics, work history, and health symptoms.

Results

The results of the study showed that healthcare workers in the exposed group had significantly higher levels of exposure to pollutants compared to those in the non-exposed group. The mean concentration of PM2.5 (particulate matter with a diameter of 2.5 micrometers or less) in the exposed group was 150 μg/m3, compared to 50 μg/m3 in the non-exposed group. The mean concentration of VOCs, including benzene, toluene, and xylene, was also significantly higher in the exposed group. PAHs and heavy metals, including lead and cadmium, were also detected in the air samples collected from the exposed group.

Health Risks

The exposure to pollutants among healthcare workers at Al Fayhaa General Teaching Hospital poses significant health risks. PM2.5 has been linked to respiratory problems, including asthma and chronic obstructive pulmonary disease (COPD). VOCs, including benzene, are known carcinogens, and exposure to them has been linked to an increased risk of cancer. PAHs and heavy metals, including lead and cadmium, have been linked to a range of health problems, including neurological damage, kidney disease, and birth defects.

Discussion

The results of this study highlight the need for effective waste management practices in healthcare facilities, particularly in developing countries where waste management infrastructure is limited. The use of incineration as a method for managing medical waste is not a sustainable solution, particularly in areas where emission control measures are not in place. Alternative methods, including autoclaving and microwave disinfection, should be considered. Additionally, healthcare workers who are occupationally exposed to pollutants should be provided with personal protective equipment, including respirators and gloves, to minimize their exposure.

Waste incineration is a significant source of pollution in healthcare facilities, particularly in developing countries. The occupational exposure to pollutants among healthcare workers at Al Fayhaa General Teaching Hospital poses significant health risks, including respiratory problems, cancer, and neurological damage. Effective waste management practices, including alternative methods for managing medical waste, should be implemented to minimize the risks associated with waste incineration. Healthcare workers who are occupationally exposed to pollutants should be provided with personal protective equipment and regular health monitoring to minimize their exposure.

Recommendations

1. Alternative methods for managing medical waste, including autoclaving and microwave disinfection, should be considered.
2. Emission control measures, including scrubbers and filters, should be installed to minimize the release of pollutants into the air.
3. Healthcare workers who are occupationally exposed to pollutants should be provided with personal protective equipment, including respirators and gloves.
4. Regular health monitoring should be conducted among healthcare workers who are occupationally exposed to pollutants.
5. Education and training programs should be implemented to raise awareness among healthcare workers about the risks associated with waste incineration and the importance of proper waste management practices.
