Assessment of the Severity of Indoor Air Pollution Sources and Control Strategies in Printing Presses in Zaria Metropolis, Nigeria

Abstract

The mitigation of indoor air pollution sources in printing facilities is crucial for ensuring healthy indoor environments and protecting the health and well-being of employees. This study assessed the severity of indoor air pollution sources and the different pollutant control strategies in use in 22 printing presses in Zaria metropolis, Kaduna State. The study adopted a quantitative method. A checklist was used to characterize the selected printing facilities and examine the severity of indoor air pollutant sources on a 5-point Likert severity scale. The instrument was also used to check the availability of Indoor Air Quality (IAQ) monitoring devices and Indoor Air Pollution (IAP) control technology/strategy currently in use in the printing facilities. Findings revealed 1 pollutant source (dust) with mean value of 3.55 to be severe, 9 others to be mild, and 11 to be non-severe. All the assessed printing presses have available compliant inks and coatings, while 100% unavailability of IAQ monitoring devices/equipment or capture systems were observed. The study concluded that by implementing effective control measures and monitoring of indoor air quality, the risk of negative health effects associated with exposure to indoor air pollutants can be minimized in the printing facilities. The study also recommended that Facility managers and policymakers must prioritize the implementation of effective control measures in printing facilities to reduce exposure to indoor air pollutants and improve IAQ, which ultimately promotes the health and well-being of press employees.
