Ambient air pollution is a global concern.It accounts for an estimated 4.2 million deaths yearly as result of its ability to cause stroke, lung cancer, heart disease and chronic respiratory diseases.It has also been that about 91 percent the world's population lives in places, mostly urban centres, where quality levels exceed World Health Organization (WHO) limits.Fortunately, efforts are regularly made most developed countries monitor reduce level ameliorate negative consequences.Unfortunately, case not same developing which Nigeria member, status rarely monitored religiously.This study geospatially assessed ambient footprints vis-à -vis land uses Calabar Metropolis, Nigeria.Data on emission CO, NO 2 , SO H S, SPM 2.5 were collected 6 months both dry wet seasons year 2020, using Crowcon Gasman, while point coordinates Garmin GPSMap 60CSx device.Geographic Information Systems (GIS) infrastructure was deployed generate maps metropolis.Descriptive parametric analytical techniques deployed, based objectives study.From findings, F-ratio significant season use all tested parameters (F-ratio F(1,3224)=574.516, at p<0.05, use, F(3,3224)=429.946, p<0.05).The interaction between (season * use) significant.It concluded there variation (CO, 2, ) Metropolis relation either types or year.It therefore recommended should be protection residential avoid encroachment by incompatible pollution.
