Palme’s tubes where used to trap Nitrogen iv oxide (NO2) in ambient air of oil producing communities of Egbema, Imo State where the Spatial distribution and toxicity assessment of pollution in six Locations where harvested, for six months. The assessment indices were ascertained using analytical instrument such as UV/Visible spectrophotometer, where samples from dry seasons in these locations where obtained. Highest concentration and average mean spread of NO2, in these locations are: 111.50µg/m3 and 66.20µg/m3 at AQEWH, while 14.51µg/m3 and 29.18 µg/m3 spread was lowest at AQAFS and AQOWH locations respectively. Total concentration of NO2 spread was also recorded as highest at 397.20µg/m3 in AQEWH and 175.08µg/m3 is lowest in AQOWH, while its toxicity potential concentrations were 1.32µg/m3 and lowest at 0.58µg/m3 in AQOWH locations respectively. Using statistical principal component analysis (PCA), which is widely used technique in meteorology and climatology, it indicates that AQEWH location has the largest variation spread of NO2, while AQOWH and AQAFS has the lowest variation spread which represents, 83.8% and 93.7%, total variability respectively during dry season.. Since long – term or chronic exposure to these pollutants on humans and environment has serious health implications, such as cardiovascular, gastrointestinal effects, chronic asthma, carcinogenic effects and chronic obstructive pulmonary disease, with responsiveness respiratory symptoms, there is every need to regularly monitor and conduct environmental air quality assessment of locations with high human activities to ascertain the level of exposure of pollutants to knowing their toxicological permissible limit
