The study evaluated air quality around host communities of oil companies in Ogba/Egbema/Ndoni Local Government Area in Rivers state. Detailed literature reviews and appropriate multi-gas observing instruments were utilized to obtain air quality information. Results of SO 2 in Omoku, Obrikum, Ebocha land Control (5km) from Oil Company indicated 214.1µg/m 3 , 0µg/m 3 , 71.4µg/m 3 and 28.5µg/m 3. NO 2 was 106µg/m 3 , 0.0µg/m 3 , 51,3µg/m 3 and 0.0µg/m 3 respectively. CH 4 was 98,120µg/m 3 , 35,680µg/m 3 and 44600µg/m 3 and 28.7µg/m 3 respectively. PM 2.5 was 54µg/m 3 , 50.5µg/m 3 , 64µg/m 3 and 50µg/m 3 respectively. CO was 93.8µg/m 3 , 62.8µg/m 3 , 78.1µg/m 3 and 0.0µg/m 3 respectively while PM 10 was 36µg/m 3 , 32µg/m 3 , 35.5µg/m 3 and 24µg/m 3 respectively. Results indicated that host communities were exposed to reasonable concentrations of air pollutants, especially hydrocarbon, carbon monoxide, nitrogen dioxide, and PM 2.5 which fall within moderate to severe air pollution level. The statistical analysis of results using ANOVA showed that the difference among the pollutants characteristics at p<0.05 are statistically significant. Federal and state governments should pay particular attention to air pollution problems in the study area by establishing air quality monitoring stations through relevant agencies.
