Article Information ABSTRACT Key Words: Air pollution, Exceedance factors, Pollutants standard, sensitive groups and Health hazards. For any information: ask.author@journalbinet.com A study on the evaluation of pollutant standard index and air quality index in Choba campus of the University of Port Harcourt, Nigeria based on particulate matter were assessed. Aeroqual-PM10/PM2.5 and CW-HAT200 particulate sampler instruments that measure particulate matter by a method of light scattering were used. Pollutant standard index and air quality index were computed using measure concentrations of PM10 and PM2.5 particulate matter. The study shows that a positive linear relationship exists between pollutant standard index and air quality index, the relationship is highly significant (p-values < 0.0001, R2 = 99.1 %). Statistical result indicates that PM2.5 constitutes 52.68% of the concentrations of PM10. PM2.5 fine particle was found to be the predominant particulate pollutant in the University Campus. Computed air quality index shows good air quality 17% of the days, moderate air quality 79% of the days and unhealthy air quality for sensitive groups 4% of the days. Sensitive groups on the campus may be experiencing coughing, shortness of breath sneezing, asthma attacks, coughing, reduced lung function and wheezing. The management of the university should communicate the air quality indices in this study to the students and public so that precautionary measures can be taken to reduce prolong exposure.

... p infig 2 and fig 3.The PM10 concentration for Lagos was not actually in the same range withTaiwo et al. (2015) who measured PM10 concentration to be within the range of 86 -8765 µg/m 3 . In 2021,Abulude et al. (2021) found the PM10 concentration for Ikeja, Lagos to be in the range of 30 -176 µg/m 3 , while Maryland was found to be 33 -173 µg/m 3 .Osimodi et al. (2019) recorded the concentration of PM2.5 in Port Harcourt to be 29. ...
