Investigation of In-situ Measurement of Pollutant Gases over Penang Island

Penang Island is experiencing rapid development in house construction and industrial activity which caused air pollution problems getting worst. Furthermore, with recent forest burning in Indonesia, the situation was become serious. Due to the increasing in air pollution problems, we decided to carry out an investigation of air pollution over Penang Island. In this paper, we used Aeroqual Series 500 Monitor (for NO2 and O-3) and MultiRAE-IR Model PGM-54 (for CO2) to perform in-situ ground level measurement over Penang Island. All measurement has been carried out every 5km journey around the Penang Island. From the data obtained, the changes of NO2, O-3 and CO2 pollutant gasses concentration over time can be study and further investigate.
