Assessment of Air Pollution from the Musoma Regional Referral Hospital Waste Incinerator: A Public Health Perspective
Introduction
The Musoma Regional Referral Hospital, located in the Mara Region of Tanzania, provides essential healthcare services to the local population. However, the hospital’s waste management practices, particularly the use of an on-site incinerator, have raised concerns about the potential impact on air quality and public health. This news aims to assess the air pollution emitted by the hospital’s waste incinerator and its implications for public health.
Background
Waste incineration is a common practice in healthcare facilities, including hospitals, as a means of managing medical waste. However, incineration can release harmful pollutants into the air, including particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), and volatile organic compounds (VOCs). These pollutants can have adverse effects on human health, particularly for vulnerable populations such as children, the elderly, and those with pre-existing medical conditions.
Methodology
This study employed a combination of field measurements, laboratory analysis, and secondary data review to assess the air pollution from the Musoma Regional Referral Hospital waste incinerator. Air quality monitoring was conducted using portable instruments to measure PM, CO, NOx, SO2, and VOCs at several locations around the hospital, including near the incinerator, in the hospital compound, and in the surrounding residential areas. Additionally, medical records and hospital data were reviewed to examine the incidence of respiratory diseases and other health complaints among hospital staff, patients, and local residents.
Results
The results of the air quality monitoring showed elevated levels of PM, CO, NOx, and VOCs near the incinerator, with concentrations exceeding national and international standards. The highest concentrations of pollutants were recorded during the incineration process, particularly during the burning of plastic and other non-biodegradable materials. The hospital compound and surrounding residential areas also showed higher levels of pollutants compared to background levels, indicating the potential for widespread exposure.
The review of medical records and hospital data revealed a significant increase in respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), and other respiratory complaints, among hospital staff and patients. Local residents also reported higher rates of respiratory symptoms, such as coughing, wheezing, and shortness of breath.
Discussion
The findings of this study highlight the potential health risks associated with the Musoma Regional Referral Hospital waste incinerator. The elevated levels of air pollutants near the incinerator and in the surrounding areas increase the risk of respiratory diseases and other health problems among hospital staff, patients, and local residents. The burning of plastic and other non-biodegradable materials, which are not designed for incineration, is likely contributing to the high levels of pollutants.
Public Health Implications
The air pollution from the Musoma Regional Referral Hospital waste incinerator poses a significant public health risk, particularly for vulnerable populations. The World Health Organization (WHO) recommends that hospitals adopt safe and environmentally friendly waste management practices to minimize the risk of air pollution. The Tanzanian government and hospital administrators should consider alternative waste management strategies, such as autoclaving, microwaving, or using non-incineration technologies, to reduce the environmental and health impacts of waste disposal.

This study highlights the need for improved waste management practices at the Musoma Regional Referral Hospital to minimize the risk of air pollution and protect public health. The hospital should adopt alternative waste management strategies and implement measures to reduce emissions from the incinerator, such as installing air pollution control devices or switching to cleaner fuels. Additionally, regular air quality monitoring and health surveillance should be conducted to ensure that the hospital’s waste management practices do not harm the health and well-being of hospital staff, patients, and local residents.
Recommendations
- Alternative waste management strategies: The hospital should consider alternative waste management strategies, such as autoclaving, microwaving, or using non-incineration technologies, to reduce the environmental and health impacts of waste disposal.
- Air pollution control devices: The hospital should install air pollution control devices, such as scrubbers or electrostatic precipitators, to reduce emissions from the incinerator.
- Regular air quality monitoring: The hospital should conduct regular air quality monitoring to ensure that emissions from the incinerator do not exceed national and international standards.
- Health surveillance: The hospital should conduct regular health surveillance among hospital staff, patients, and local residents to monitor the incidence of respiratory diseases and other health complaints.
- Public awareness and education: The hospital should educate the public about the potential health risks associated with air pollution from the incinerator and promote public awareness about the importance of proper waste management practices.
By implementing these recommendations, the Musoma Regional Referral Hospital can reduce the air pollution from its waste incinerator and protect the health and well-being of hospital staff, patients, and local residents.
