Determining The Concentration of Criteria Pollutants in Bonny Island from Industrial Activities

This research paper presented the investigation of the concentration of selected criteria pollutants from Industrial activities in Bonny Island. The research was carried out for a total of two months, each both at the rainy and dry seasons. Readings were taken at a distance of 100meters from the stack emitting gaseous pollutants from the NLNG plant. Air pollutant parameters measured were PM2.5, PM10, CO, NOX, O3 and SO2 in line with international standards. The determination of selected criteria pollutants [CO, NOX, O3, SO2, PM2.5 and PM10] content of Bonny Island environments during dry and wet seasons at selected sampling point for 2 months each in the studied environment showed concentrations ranging from 0.142 to 0.599, 0.005 to 0.013, 0.011 to 0.023, 0.002 to 0.004, 5.80 to 43.45 and 6.32 to 47.25ug/m3 for dry seasons of CO, NOX, O3, SO2, PM2.5, and PM10; and 0.458 to 0.821, 0.002 to 0.013, 0.011 to 0.027, 0.002 to 0.004, 5.0 to 38.29, and 4.84 to 19.76ug/m3 for wet season of CO, NOX, O3, SO2, PM2.5, and PM10 respectively. Results of the analysis conducted showed that CO, NOX, O3, SO2, PM2.5, and PM10 concentration were below World Health Organizations [WHO] allowable limits and are acceptable for human.
