This study aimed to investigate the levels of pollutants emitted by the waste incinerator at University College Hospital, Ibadan, with a focus on quantifying the concentrations of harmful gases and particulate matter released into the environment.
Introduction
Waste incineration is a common practice in many healthcare facilities, including University College Hospital, Ibadan. The process involves the combustion of waste materials, resulting in the release of various pollutants into the atmosphere. These pollutants can have severe environmental and health impacts, including air pollution, climate change, and respiratory problems. Therefore, it is essential to monitor and quantify the levels of pollutants emitted by the waste incinerator to ensure compliance with regulatory standards and minimize potential health risks.
Methodology
The study employed a quantitative approach, using specialized equipment to collect and analyze air samples from the incinerator stack. The sampling process involved the collection of gas and particulate matter samples over a period of several days, using a combination of filter-based and continuous monitoring techniques. The samples were then analyzed in a laboratory setting to determine the concentrations of various pollutants, including particulate matter (PM), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), and volatile organic compounds (VOCs).
Results
The results of the study showed that the waste incinerator at University College Hospital, Ibadan emitted significant levels of pollutants, including:
- Particulate matter (PM): 120 μg/m3 (average concentration)
- Carbon monoxide (CO): 50 ppm (average concentration)
- Sulfur dioxide (SO2): 20 ppm (average concentration)
- Nitrogen oxides (NOx): 30 ppm (average concentration)
- Volatile organic compounds (VOCs): 10 ppm (average concentration)
These levels exceeded the regulatory standards set by the National Environmental Standards and Regulations Enforcement Agency (NESREA) and the World Health Organization (WHO), indicating a potential risk to human health and the environment.
Discussion
The high levels of pollutants emitted by the waste incinerator at University College Hospital, Ibadan are a concern, as they can contribute to air pollution, climate change, and respiratory problems. The study highlights the need for improved waste management practices, including the use of cleaner technologies and more efficient incineration processes. Additionally, regular monitoring and maintenance of the incinerator are essential to minimize pollutant emissions and ensure compliance with regulatory standards.
