ANALYSIS OF SOME AIR POLLUTANTS IN YOLA NORTH LOCAL GOVERNMENT AREA, ADAMAWA STATE, NIGERIA
The environmental burden of air pollution has been known to be the largest environmental health risk to mankind today. Ambient daily concentration levels of carbon monoxide (CO), Nitrogen dioxide(NO2) and Sulphur dioxide (SO2) status of eleven wards in Yola North local government areas were studied in the morning, afternoon and in the evening for a period of six weeks in months of February to March in 2018 using Crowcon Tetra 3 mobile gas sensor with model number IECEX BAS 05.0059. The mean concentration values of 34.0ppm, 28.0ppm,22.4ppm, 32.0ppm and 26.0ppm of (CO) was recorded in Rumde, Demsawo, Yelwa, Luggere and Doubeli and (NO2) concentration levels of 0.056ppm, 0.071ppm,0.070ppm, and 0.073ppm was recorded for Rumde, Karewa, Luggere and Doubeli respectively. While the concentration levels of (SO2) at the eleven wards were all found to be above the standard of 0.03ppm set limits. The higher concentrations of CO, NO2 and SO2 observed in this study is alarmingly higher than the safe limits of 20ppm, 0.053ppm and 0.03ppm set by NESREA standard and the air pollutants were mostly found to be higher in the morning and evening hours. The observed high concentration levels CO, NO2 and SO2 means that air quality in Yola North is strongly impaired and capable of triggering public health especially now that the whole world is battling with Covid 19 which is also airborne. Wearing face masks and constant monitoring air quality is recommended.
