A monitoring assessment was carried out to measure the concentration of air pollutants in ambient air in the university campus, which is located adjacent to the industrial area. The air pollutants were monitored for CO (Carbon monoxide), SO2 (Sulfur dioxide) and NO (Nitrous oxide) at the three sampling points, with distance reference based from the industrial area. Air pollutant gases were sampled from the I-Brid Toxic Gases Analyzer with the sampling hour referred to the Recommended Malaysian Air Quality Guidelines (RMAQG) during October 2013 to Jun 2014. Meteorological data was collected from the E-Sampler device for 24 hours. It was found that the CO concentrations were fall within the RMAQG at all stations monitored. The SO2 concentration was high at Station 3 (Material lab), with 0.66 ppm which was exceeded the RMAQG of 0.13 ppm. All three stations recorded high concentration of NO, which the peak concentration occurred at the afternoon sampling. The nearest Station 3 (Material lab) has recorded the highest level of NO, SO2 and CO compared to the other stations. The monitoring data has contributed some highlights to the authority and awareness about possible long risk effect of the air pollutants at the case study.
