This study examines environmental and health risk implications of air quality in the vicinity of the Port Harcourt airport road dumpsite. The study objectives are to determine air quality in the vicinity of the Port Harcourt airport road dumpsite of the municipal solid waste, examine the health risk implications of air quality in the study location, ascertain the environmental implications of the air quality in the vicinity of the dumpsite, and identify if there are variations in air quality in the different sections in the study location. Air quality was determined using standard operating procedures where samples were collected at the dump, 250 m and 500 m away from the dumpsite. The samples were collected in the morning, afternoon and evening hours of the same day. The samples collected from these locations were taken in-situ amongst which are (Co2, CH4, O2, Co, H2S, PM-2.5, PM-10, Ni, Cr, Temperature and RH). Survey questionnaire was administered, in order to complement the field results. Three hypotheses were also tested using ANOVA and the Chi-square analytical tool. The findings of the study show that Nickel and Chromium amongst other parameters were above the WHO standard limits. Therefore, the quality of air within the vicinity of the dumpsite is considered polluted. Consequently, URTI and skin rashes are the common ailments that are prevalent in the area of study. Thus, the municipal solid waste dumpsite constitutes both environmental and health implications to the human population within the vicinity of the Port Harcourt airport road dumpsite. In this regard, this study recommends that the citing of waste dump should be done in line with standard regulations and prohibits the development of residential settlements within 3 km radius from any dumpsite.
