The determination of air pollutants in Abattoir, Ntak Inyang in Uyo L.G.A was carried out using standard analytical techniques. The pollutants monitored were NO2, SO2, H2S, CO, NH3, Cl2, TVOC, CH2O, PM2.5, PM10, Temp, Relative humidity (RH), Pressure and Wind Speed (WS). The results for the concentration of air pollutant and their Air Quality Index (AQI) reveals as follows NO2(1.36 ± 0.32(ppm), AQ1=1360). SO2(2.44 ± 1.98(ppm), AQ1=488). H2S (3.38 ± 1940(ppm), AQ1=19450). CO (1.79±1.61(ppm), AQ1=334). NH3(7.8±2.26(ppm), AQ1=156). Cl2(1.47± 1.29(ppm), AQ1= 147). HCN (11.56±7.93(mg/m3), AQ1=115,600). TVOC (164±0.46(mg/m3), AQ1=328). CH2O (0.23±0.12(mg/m3), AQ1=0.276). PM2.5(43.2±0.95(μg/m3), AQ1=172.8). PM10(74.8±1.15(μg/m3), AQ1=149.6). Temp (27.5±4.6oC). Relative humidity (RH) (74.6 ± 4.6%), Press (1006.7±0.84(kpa). W.S (1.56±0(m/s)). The result showed that NO2, SO2, H2S, CO, NH3, Cl2, HCN, TVOC, PM2.5and PM10were higher than that of FEPA standard limit. The correlation analysis revealed that NO2shows positive relationship with H2S, and W.S at 0.05 significant level and negatively with Cl2and Press at 0.01 significant level, and negatively with PM2.5and PM10 at 0.05 significant level. SO2correlated positively with CO at 0.01 significant level, TVOC and CH2O at 0.05 significant level. SO2-NH3at 0.05 significant level but negatively. H2S shows a relationship with Temp but positively at 0.01 significant leveland 0.05 significant level with HCN, H2S also correlated negatively with NH3and Press at 0.01 significant level. While CO shows a correlation with NH3at 0.05 significant level but negatively. NH3-RH positively at 0.01 significant, NH3-Press at 0.05 significant level. Also, NH3shows a negative relationship with TVOC, CH2O and Temp at 0.05 significant level. Cl2correlated strongly but positively with Press at 0.01significant level, Cl2-PM2.5and PM10at 0.05 significant level and a negative relationship with W.S at 0.05 significant level. HCN-WS negatively at a 0.05 significant level. TVOC correlated positively with CH2O and negatively with RH at 0.01 significant level, and a positive relationship with PM2.5and PM10at 0.05 significant level. CH2O correlated negatively with RH at 0.01 significant level and positively with PM2.5and PM10at 0.05 significant level. PM2.5 shows a positively relationship with PM10at 0.01 significant level. This result in an indication of the presence of possible air pollutants in the of the study area which may results in many health problems.
