The Federal College of Agriculture in Akure, Nigeria, was the site of this study, which aimed to monitor indoor air quality (PM2.5and PM10) and toxicity potential. The novelty of the study is: it is the first one in Africa to employ a cheap sensor called the Canāree A1 to measure the indoor air quality of a tertiary institution in Nigeria. The study offers baseline data for the next investigations and the formulation of policies regarding indoor air quality in Nigeria. Five distinct places were selected for the preliminary investigation, which lasted for 1 month. The protocols from the manufacturer were strictly followed. The findings revealed that while PM10levels were 2.3–13.1 times greater than 2021 World Health Organization (WHO) standards, PM2.5readings were 5.8–20.3 times higher. Additionally, it exceeded The National Environmental Standards and Regulations Enforcement Agency (NESREA) guidelines by 1.2–6.6 times for PM2.5and 0.7–3.9 times for PM10, respectively. Other findings include the following: Toxicity Potential (TP) ranges from 5.28 to 33.14 for PM2.5and 2.30–8.33 for PM10; Indoor air quality index (IAQIndex) ranges from 1.16 to 6.63 for PM2.5and 0.69–3.91 for PM10; and PM size distribution is from 0.31 to 0.34 for PM1.0/PM2.5, 0.34–0.84 for PM2.5, and 0.25–0.34 for PM10, respectively. The findings indicated that the study’s study sites were contaminated, since the TP levels were higher than 1. An attempt should be made to lessen anthropogenic and non-anthropogenic activities’ indoors. It is crucial that all parties involved in environmental issues comprehend the causes, effects, and mitigations of climate change. |
